King Richard III: DNA and genealogical study confirms identity of remains found in Leicester and uncovers new truths about his appearance and Plantagenet lineage

International research led by the University of Leicester published in Nature Communications reveals:

  • Analysis of all the available evidence confirms identity of King Richard III to the point of 99.999% (at its most conservative).
  • Analysis of the mitochondrial DNA shows a match between Richard III and modern female-line relatives, Michael Ibsen and Wendy Duldig.
  • The male line of descent is broken at one or more points in the line between Richard III and living male-line relatives descended from Henry Somerset, 5th Duke of Beaufort.
  • King Richard was almost certainly blue-eyed and probably had blond hair at least during his childhood.
  • The portrait which appears to most closely match the genetically-determined hair and eye colour is the Arched-Frame Portrait in the Society of Antiquaries.

An international research team led by Dr Turi King from the University of Leicester Department of Genetics provides overwhelming evidence that the skeleton discovered under a car park in Leicester indeed represents the remains of King Richard III, thereby closing what is probably the oldest forensic case solved to date.

The team of researchers, including Professor of English Local History, Kevin Schürer, who is also Pro-Vice-Chancellor for Research at the University of Leicester, who led the genealogical research for the project, has published their findings online today (Tuesday 2 December) in the prestigious peer-reviewed journal Nature Communications.

The researchers collected DNA from living relatives of Richard III and analysed several genetic markers, including the complete mitochondrial genomes, inherited through the maternal line, and Y-chromosomal markers, inherited through the paternal line, from both the skeletal remains and the living relatives.

While the Y-chromosomal markers differ, the mitochondrial genome shows a genetic match between the skeleton and the maternal line relatives. The former result is not unsurprising as the chances for a false-paternity event is fairly high after so many generations. This paper is also the first to carry out a statistical analysis of all the evidence together to prove beyond reasonable doubt that Skeleton 1 from the Greyfriars site in Leicester is indeed the remains of King Richard III.

The researchers also used genetic markers to determine hair and eye colour of RIII and found that with probably blond hair and almost certainly blue eyes RIII looked most similar to his depiction in one of the earliest portraits of him that survived, that in the Society of Antiquaries in London.

The research team now plans to sequence the complete genome of RIII to learn more about the last English king to die in battle.

The University of Leicester was the principal funder of the research. Dr King’s post is part-funded by The Wellcome Trust and the Leverhulme Trust.

Dr King said:

“Our paper covers all the genetic and genealogical analysis involved in the identification of the remains of Skeleton 1 from the Greyfriars site in Leicester and is the first to draw together all the strands of evidence to come to a conclusion about the identity of those remains. Even with our highly conservative analysis, the evidence is overwhelming that these are indeed the remains of King Richard III, thereby closing an over 500 year old missing person’s case.”

Professor Schürer added:

“The combination of evidence confirms the remains as those of Richard III. Especially important is the triangulation of the maternal line descendants. The break in the Y-chromosome line is not overly surprising given the incidence of non-paternity, but does pose interesting speculative questions over succession as a result.”

Simon Chaplin, Director of Culture & Society at the Wellcome Trust, added: “It is exciting to have access to genetic data from any known historical individual, let alone a king of England lost for more than 500 years, so we are thrilled to be able to support this fascinating project through our Research Resources grant scheme. Adding this information to a wealth of existing material about Richard III further highlights the ways in which studying human remains can inform our understanding of the past, and we look forward to learning more about Richard for many years to come.”

Research team discover the world’s largest ancient stone block in Baalbek

0

In the summer of 2014, the Oriental Department of the German Archaeological Institute led excavations in the quarry of Baalbek Heliopolis (Lebanon) and discovered the world’s largest ancient quarried stone block.

The monolithic block is a staggering 19.60 m long, 6 m wide and at least 5.5 m high with an estimated weight of 1650 tons. Stones like this were quarried for the podium of a temple dedicated to Jupiter in the Roman sanctuary of Baalbek.

The team is currently investigating why the stone was never completed and left in the quarry – and by what means could the stone block be transported.

Studying the machining marks on a similar 1000 ton monolith, named “Hajjar al-Hibla” (Stone of the Pregnant Woman) their data revealed that Hajjar al-Hibla was left in the quarry due to the poor stone quality on the block’s edge that could leave it prone to damage during transport.

The larger monolith, located in the stone layer under the Hajjar al- Hibla has a narrow side already worked to a smooth face and would have been transported as a single block.

Archaeologists also investigated the waste dumps of the mining activities, in order to locate datable and stratifiable sherds of pottery and small finds.

The giant monolith will be further investigated to gain exact dimensions during the next phase of archaeological investigations.

The research was undertaken  with the supervision of Prof. Dr. Abdul Massih Jeanine , Lebanese University and the Baalbek Project of the Orient Department of the German Archaeological Institute, in cooperation with the Lebanese Council of Antiquities.

Scientists find 240 million-year-old parasite that infected mammals’ ancestor

0

An egg much smaller than a common grain of sand and found in a tiny piece of fossilized dung has helped scientists identify a pinworm that lived 240 million years ago.

It is believed to be the most ancient pinworm yet found in the fossil record.

The discovery confirms that herbivorous cynodonts — the ancestors of mammals — were infected with the parasitic nematodes. It also makes it even more likely that herbivorous dinosaurs carried pinworms.

Scott Gardner, a parasitologist and director of the Harold W. Manter Laboratory of Parasitology at the University of Nebraska-Lincoln, was among an international group of scientists who published the study in the journal Parasites & Vectors.

“This discovery represents a first for our team and I think it opens the door to finding additional parasites in other species of fossil organisms,” he said.

The team found the pinworm egg in a coprolite — fossilized feces — collected in 2007 at an excavation site in Rio Grande do Sul state in southern Brazil.

The coprolite was collected at a site with abundant fossilized remains of cynodonts. Previously, an Ascarid-like egg — resembling a species of nematode commonly found in modern-day mammals — was found in the coprolite.

The pinworm egg, representing an undescribed or “new species,” was named Paleoxyuris cockburni, in honor of Aidan Cockburn, founder of the Paleopathology Association.

The structure of the pinworm egg placed it in a biological group of parasites that occur in animals that ingest large amounts of plant material. Its presence helped scientists deduce which cynodont species, of several found at the collection site, most likely deposited the coprolite.

Since the field of paleoparasitology, or the study of ancient parasites, emerged in the early 20th century, scientists have identified parasites of both plants and animals that date back as far as 500 million years ago.

The study of parasites in ancient animals can help determine the age of fossilized organisms and help establish dates of origin and diversification for association between host species and parasites. Coprolites are a key part of the study, enabling a better understanding of the ecological relationships between hosts and parasites.

Other members of the team were Jean-Pierre Hugot of the National Museum of Natural History in Paris; Victor Borba, Juliana Dutra, Luiz Fernando Ferreira and Adauto Araujo of Oswaldo Cruz Foundation in Rio de Janeiro; Prisiclla Araujo and Daniela Leles of Fluminense Federal University in Rio de Janeiro; and Atila August Stock Da-Rosa of the Federal University of Santa Maria in Rio Grande do Sul.

Excavating WWI practice trenches in Cumbria

Excavations and surveys of the First World War practice trenches on Walney Island on the western coast of Cumbria have been carried out by a team of archaeologists from the University of Bristol.

As part of a Heritage Lottery Fund community project, established by internationally-renowned, artist-led company Art Gene Associates, Bristol archaeologist Dr George Nash and former Bristol MA graduate and professional archaeologist Thomas Wellicome trained volunteers to excavate two trenches over the western part of a practice trench system that is believed to date from the early months of World War I.

The practice trench system is located close to the Cumbrian coastline within the northern part of Walney Island, near the naval shipyards of Barrow-in-Furness. Within the vicinity of the practice trenches are further military installations that include a World War I rifle butts and range, World War II moving target range and RAF Walney, which was established as a gunnery school and airfield in late 1941. Currently, the trenching system stands within a National Nature Reserve, managed by Natural England.

Dr Nash said: “In many ways the military history of Walney Island is still very much an enigma. Researchers are faced with limited documentary evidence, Ordnance Survey map embargoes between 1916 and 1985, and little in the way of surviving above-ground archaeology.”

Following a desk-based assessment and a walkover survey to assist in targeting the trenching, two trenches (each measuring three by two metres) over the far western section of the practice trench system were excavated. The World War I practice trenching was also surveyed. The archaeologists believe this project is the first of its kind to be undertaken on World War I practice trenching in the UK.

The field survey has now completely mapped out the crenulated earthwork, along with previously unrecorded trench sections and features which stand to the south. Much of the newly-discovered trenching was uncovered during the walkover survey by volunteers.

The archaeologists also conducted an earthwork survey of the World War I trenching and World War II gun range which will be used by Art Gene in the development of a planned augmented-reality mobile phone app to help visitors better understand this poignant military landscape.

The excavation revealed the outline of the trench edges and base but any timber or metal shoring that propped up the trench system had long-since gone. An array of artefacts that were, not surprisingly, associated with military activity, were discovered including numerous .303 bullet-head and the occasional shell case. Analysis has shown that these items date to 1915/16 and were made in America. Also found was a British coin that dated to around 1840: had this coin accidentally fallen out of the pocket of a soldier?

By chance on the last day of the excavation, local resident Andrew Bolton showed the team several photographs of his grandfather, 43894 Private Hugh Thomas of the Royal Welsh Fusiliers, in uniform. Mr Thomas was one of many soldiers to use the practice trenches on North Walney between July 1916 and January 1917 prior to being sent to the Western Front to fight at Passchendaele and the 3rd Battle of Ypres that year.

Dr Nash said: “This is probably the closest we can get to the horrors of early modern warfare. Based on the limited finds and artefacts shown to the team, the practice trenches on North Walney were a busy place with conscripts and professional soldiers learning how to use shallow trenching, especially prior to 1916 when battle field tactics began to change forever with trench warfare becoming a three-year stalemate along the Western Front.”

It is hoped that the outcome of this project will further interest the people of Walney and neighbouring Barrow-in-Furness to further explore their own back yards. Judging by the positive comments made by bystanders over the duration of the excavation, it is clear that there is more to learn about this fascinating and unexplored corner of Cumbria.

The Art Gene team are indebted to Cumbria’s Archaeology Service for providing invaluable Historic Environment Record and English Heritage project information about this corner of the North-west.

American Mastodons Made Warm Arctic, Subarctic Temporary Home 125,000 Years Ago

0

New findings published this week in the Proceedings of the National Academy of Sciences byan international team of researchers, including Museum Curator Ross MacPhee, are revising estimates of the age of American mastodon fossils—and helping to resolve a quandary about how these extinct relatives of elephants once lived in the Arctic and Subarctic.

Over the course of the late Pleistocene, between about 10,000 and 125,000 years ago, the American mastodon became widespread and occupied many parts of continental North America as well as peripheral locations like the tropics of Honduras and the Arctic coast of Alaska.

Existing age estimates of American mastodon fossils had indicated that these animals lived in the Arctic and Subarctic when the area was covered by ice caps—a timeline that was at odds with what scientists know about the massive animals’ preferred habitat: forests and wetlands abundant with leafy food.

The new research, which adjusts fossil age estimates based on new radiocarbon dates, suggests that the Arctic and Subarctic were only temporary homes to mastodons when the climate there was warm.

“Mastodon teeth were effective at stripping and crushing twigs, leaves, and stems from shrubs and trees. So it would seem unlikely that they were able to survive in the ice-covered regions of Alaska and Yukon during the last full-glacial period, as previous fossil dating has suggested,” said Grant Zazula, a paleontologist in the Yukon Paleontology Program and lead author on the new work.

The new findings also indicate that mastodons suffered local extinction in the north several tens of millennia before either human colonization—the earliest estimate of which is between 13,000 and 14,000 years ago—or the onset of climate changes at the end of the ice age about 10,000 years ago, when they were among 70 species of mammals to disappear in North America.

“Scientists have been trying to piece together information on these extinctions for decades,” said Dr. MacPhee, a curator in the Department of Mammalogy. “Was is the result of over-hunting by early people in North America? Was it the rapid global warming at the end of the ice age? Did all of these big mammals go out in one dramatic die-off, or were they paced over time and due to a complex set of factors?”

The research team used two different types of precise radiocarbon dating on a collection of 36 fossil teeth and bones of American mastodons from Alaska and Yukon, the region known as eastern Beringia.

The dating methods, performed at Oxford University and the University of California, Irvine, are designed to only target material from bone collagen, not accompanying “slop,” including preparation varnish and glues that were used many years ago to strengthen the specimens.

All of the fossils were found to be older than previously thought, with most surpassing 50,000 years, the effective limit of radiocarbon dating. Taking mastodon habitat preferences and other ecological and geological information into account, the results indicate that mastodons probably only lived in the Arctic and Subarctic for a limited time around 125,000 years ago, when forests and wetlands were established and the temperatures were as warm as they are today.

“The residency of mastodons in the north did not last long,” Zazula said. “The return to cold, dry glacial conditions along with the advance of continental glaciers around 75,000 years ago effectively wiped out their habitats. Mastodons disappeared from Beringia, and their populations became displaced to areas much farther to the south, where they ultimately suffered complete extinction about 10,000 years ago.”

Researchers know that giant ground sloths, American camels, and giant beavers made the migration as well, but they are still investigating what other groups of animals might have followed this course.

The new report also suggests that humans could not have been involved in the local extinction of mastodons in the north 75,000 years ago as they had not yet crossed the Bering Isthmus from Asia.

“We’re not saying that humans were uninvolved in the megafauna’s last stand 10,000 years ago,” MacPhee said. “But by that time, whatever the mastodon population was down to, their range had shrunken mostly to the Great Lakes region. That’s a very different scenario from saying the human depredations caused universal loss of mastodons across their entire range within the space of a few hundred years, which is the conventional view.”

Mass extinction led to many new species of bony fish

0

Today, ray-finned fish, which belong to the bony fish, are by far the most biodiverse fish group in both salt- and freshwater.

Their spectacular variety of forms ranges from eels, tuna, flounders and angler fish all the way to seahorses. With around 1,100 species, the second most biodiverse group is the cartilaginous fish, which are almost exclusively marine and include sharks, rays and chimaeras. Exactly why bony fish managed to prevail in different habitats is the subject of debate: Do they have a better body plan, which is suited to more ecological niches than that of the cartilaginous fish? Or are other factors involved in their successful distribution? Paleontologists from the University of Zurich now reveal that climate catastrophes in the past played a crucial role in the dominance of ray-finned fish today.

Cartilaginous fish greatly depleted by extinction events

The scientists studied the changes in biodiversity among cartilaginous and bony fish during the Permian and Triassic periods around 300 to 200 million years ago – an interval marked by several serious extinction events. They evaluated the global scientific literature on bony and cartilaginous fish from the last 200 years and collected data on diversity and body size, the latter providing an indication of the fish’s position in the food chains in the seas and freshwater.

Based on the data evaluated, the researchers demonstrate that cartilaginous fish, the most biodiverse fish group at the time, especially suffered heavily during an extinction event in the Middle Permian epoch while the Permian ray-finned fish escaped relatively unscathed. After an even bigger mass extinction close to the Permian-Triassic boundary, which wiped out 96 percent of all sea organisms, these bony fish diversified heavily. Of the ray-finned fish, the so-called Neopterygii (“new fins”) became particular biodiverse during the Triassic and, with over 30,000 species, today constitute the largest vertebrate group. Triassic Neopterygii primarily developed small species while the majority of the more basal ray-fins produced large predatory fish. Moreover, many bony fish developed morphological specializations in the Triassic, such as in the jaw apparatus, dentition or fins. This enabled new ways of locomotion, including gliding over the surface of the water, much like flying fish do today. Moreover, there is also evidence for viviparity in Triassic bony fish, for the first time ever.

Extinction events correlate with climate changes

Unlike bony fish, cartilaginous fish, which had already been heavily decimated by the end of the Permian, did not really recover. Many groups that were still biodiverse in the Permian disappeared completely or became extremely rare during the extinction events of the Permian and the Triassic. “Our results indicate that repeated extinction events played a key role in the development of today’s fish fauna,” explains Carlo Romano, a postdoc at the University of Zurich’s Paleontological Institute and Museum. Most of these severe crises are linked to massive volcanic activity, global climate changes and sea level lowstands.

Ancient Greek Antikythera Mechanism reveals surprising advances in early science

0

Two researchers have published a paper advancing our understanding of the Antikythera Mechanism, an ancient Greek mechanism that modeled the known universe of 2,000 years ago.

The heavily encrusted, clocklike mechanism—dubbed the “world’s first computer”—was retrieved from an ancient shipwreck on the bottom of the sea off Greece in 1901.

After several years of studying the mechanism and Babylonian records of eclipses, the collaborators have pinpointed the date when the mechanism was timed to begin—205 B.C.  This suggests the mechanism is 50–100 years older than most researchers in the field have thought.

The new work (published in the Archive for History of Exact Science) fills a gap in ancient scientific history by indicating that the Greeks were able to predict eclipses and engineer a highly complex machine—sometimes called the world’s first computer—at an earlier stage than believed. It also supports the idea that the eclipse prediction scheme was not based on Greek trigonometry (which was nonexistent in 205 B.C.)—but on Babylonian arithmetical methods, borrowed by the Greeks.

Far more conjecturally, this timing also makes an old story told by Cicero more plausible—that a similar mechanism was created by Archimedes and carried back to Rome by the Roman general Marcellus, after the sack of Syracuse and the death of Archimedes in 212 B.C. If the Antikythera mechanism did indeed use an eclipse predictor that worked best for a cycle starting in 205 BC, the likely origin of this machine is tantalizingly close to the lifetime of Archimedes.

Evans and Carman arrived at the 205 B.C. date using a method of elimination that they devised. Beginning with the hundreds of ways that the Antikythera’s eclipse patterns could fit Babylonian records (as reconstructed by John Steele, Brown University) the team used their system to eliminate dates successively, until they had a single possibility.

The calculations take into account lunar and solar anomalies (which result in faster or slower velocity), missing solar eclipses, lunar and solar eclipse­s cycles, and other astronomical phenomena. The work was particularly difficult because only about a third of the Antikythera’s eclipse predictor is preserved.

The new online paper will appear in the journal’s January 2015 hard copy edition.

The palaeolithic diet and the unprovable links to our past

0

We still hear and read a lot about how a diet based on what our Stone Age ancestors ate may be a cure-all for modern ills. But can we really run the clock backwards and find the optimal way to eat? It’s a largely impossible dream based on a set of fallacies about our ancestors.

There are a lot of guides and books on the palaeolithic diet, the origins of which have already been questioned.

It’s all based on an idea that’s been around for decades in anthropology and nutritional science; namely that we might ascribe many of the problems faced by modern society to the shift by our hunter-gatherer ancestors to farming roughly 10,000 years ago.

Many advocates of the palaeolithic diet even claim it’s the only diet compatible with human genetics and contains all the nutrients our bodies apparently evolved to thrive on.

While it has a real appeal, when we dig a little deeper into the science behind it we find the prescription for a palaeolithic diet is little more than a fad and might be dangerous to our health.

Mismatched to the modern world

The basic argument goes something like this: over millions of years natural selection designed humans to live as hunter-gatherers, so we are genetically “mismatched” for the modern urbanised lifestyle, which is very different to how our pre-agricultural ancestors lived.

The idea that our genome isn’t suited to our modern way of life began with a highly influential article by Eaton and Konner published in the New England Journal of Medicine in 1985.

Advocates of the palaeolithic diet, traceable back to Eaton and Konner’s work, have uncritically assumed a gene-culture mismatch has led to an epidemic in “diseases of civilisation”.

Humans are, it’s argued, genetically hunter-gatherers and evolution has been unable to keep pace with the rapid cultural change experienced over the last 10,000 years.

These assumptions are difficult to test or even outright wrong.

What did our Stone Age ancestors eat?

Proponents of the palaeolithic diet mostly claim that science has a good understanding of what our hunter-gatherer ancestors ate.

Let me disavow you of this myth straight away – we don’t – and the further back in time we go the less we know.

What we think we know is based on a mixture of ethnographic studies of recent (historical) foraging groups, reconstructions based on the archaeological and fossil records and more recently, genetic investigations.

We need to be careful because in many cases these historical foragers lived in “marginal” environments that were not of interest to farmers. Some represent people who were farmers but returned to a hunter-gatherer economy while others had a “mixed” economy based on wild-caught foods supplemented by bought (even manufactured) foods.

The archaeological and fossil records are strongly biased towards things that will preserve or fossilise and in places where they will remain buried and undisturbed for thousands of years.

What this all means is we know little about the plant foods and only a little bit more about some of the animals eaten by our Stone Age ancestors.

Many variations in Stone Age lifestyle

Life was tough in the Stone Age, with high infant and maternal mortality and short lifespans. Seasonal shortages in food would have meant that starvation was common and may have been an annual event.

People were very much at the mercy of the natural environment. During the Ice Age, massive climate changes would have resulted in regular dislocations of people and the extinction of whole tribes periodically.

Strict cultural rules would have made very clear the role played by individuals in society, and each group was different according to traditions and their natural environment.

This included gender-specific roles and even rules about what foods you could and couldn’t eat, regardless of their nutritional content or availability.

For advocates of the palaeolithic lifestyle, life at this time is portrayed as a kind of biological paradise, with people living as evolution had designed them to: as genetically predetermined hunter-gatherers fit for their environment.

But when ethnographic records and archaeological sites are studied we find a great deal of variation in the diet and behaviour, including activity levels, of recent foragers.

Our ancestors – and even more recent hunter-gatherers in Australia – exploited foods as they became available each week and every season. They ate a vast range of foods throughout the year.

They were seasonably mobile to take advantage of this: recent foraging groups moved camps on average 16 times a year, but within a wide range of two to 60 times a year.

There seems to have been one universal, though: all people ate animal foods. How much depended on where on the planet you lived: rainforests provided few mammal resources, while the arctic region provided very little else.

Studies show on average about 40% of their diet comprised hunted foods, excluding foods gathered or fished. If we add fishing, it rises to 60%.

Even among arctic people such the as Inuit whose diet was entirely animal foods at certain times, geneticists have failed to find any mutations enhancing people’s capacity to survive on such an extreme diet.

Research from anthropology, nutritional science, genetics and even psychology now also shows that our food preferences are partly determined in utero and are mostly established during childhood from cultural preferences within our environment.

The picture is rapidly emerging that genetics play a pretty minor role in determining the specifics of our diet. Our physical and cultural environment mostly determines what we eat.

Evolution didn’t end at the Stone Age

One of the central themes in any palaeolithic diet is to draw on the arguments that our bodies have not evolved much over the past 10,000 years to adapt to agriculture-based foods sources. This is nonsense.

There is now abundant evidence for widespread genetic change that occurred during the Neolithic or with the beginnings of agriculture.

Large-scale genomic studies have found that more than 70% of protein coding gene variants and around 90% of disease causing variants in living people whose ancestors were agriculturalists arose in the past 5,000 years or so.

Textbook examples include genes associated with lactose tolerance, starch digestion, alcohol metabolism, detoxification of plant food compounds and the metabolism of protein and carbohydrates: all mutations associated with a change in diet.

The regular handling of domesticated animals, and crowded living conditions that eventually exposed people to disease-bearing insects and rodents, led to an assault on our immune system.

It has even been suggested that the light hair, eye and skin colour seen in Europeans may have resulted from a diet poor in vitamin D among early farmers, and the need to produce more of it through increased UV light exposure and absorption.

So again, extensive evidence has emerged that humans have evolved significantly since the Stone Age and continue to do so, despite some uninformed commentators still questioning whether evolution in humans has stalled.

A difficult choice

In the end, the choices we make about what to eat should be based on good science, not some fantasy about a lost Stone Age paradise.

In other words, like other areas of preventative medicine, our diet and lifestyle choices should be based on scientific evidence not the latest, and perhaps even harmful, commercial fad.

If there is one clear message from ethnographic studies of recent hunter-gatherers it’s that variation – in lifestyle and diet – was the norm.

There is no single lifestyle or diet that fits all people today or in the past, let alone the genome of our whole species.

Macabre skeletal finds shed new light on the Sandby borg massacre

1

During the excavation of Sandby borg ringfort on the island of Öland, Sweden, a number of macabre finds were made. Skeletal remains from a small child were found in one of the houses in the ringforts central block.

This is the first child to be identified among the victims of the massacre at Sandby borg. It is both frightening and sensational in the sense that prior to this find the results showed that there had only been adults in the ringfort when this horrific event took place, says Helena Victor , project manager at the Dept. of Museum Archaeology at Kalmar County Museum, Sweden.

It sheds a whole new light on the massacre, she continues. The excavation was carried out in September by the Department of Museum Archaeology at Kalmar County Museum, in cooperation with students from Linnaeus University.

Osteological analyses have now been made of the bones that were uncovered and experts confirm that they belong to two individuals, one of which is a child of an estimated age of 2 to 5 years.

In the same house the skeleton of a middle – aged, 50 to 60 year old man was found lying on its stomach in the central of the building.

What we can see by looking at the position in which the skeleton was found is that he was probably struck down and fell prone into the burning fireplace, says Clara Alfsdotter, osteologist at the museum of Bohuslän who conducted the analysis.

Tragically he’s been left there, lying in the burning fireplace, which is a terrible fate.

The Sandby borg research was started in 2010.

Despite the fact that less than 3 % of the ringfort have been excavated, the remains of over ten individuals have been uncovered and all of them show indications to having died in a violent massacre that took place around 1500 years ago.

The researchers are now pleading for the public to donate so that the work can continue.

We need funding to be able to continue, Helena Victor explains.

So we’re launching a crowdfunding campaign, where one of the rewards for funding will be to join us in the trench at the next Sandby borg excavation.

It is the first time in Sweden that an archaeological crowdfunding campaign has been started.

The Sandby borg crowdfunding campaign will run between November 27 and December 31, 2013

The emergence of modern sea ice in the Arctic Ocean, 2.6 million years ago

In an international collaborative project, Knies has studied the historic emergence of the ice in the Arctic Ocean. The results are published in Nature Communications.

“We have not seen an ice free period in the Arctic Ocean for 2,6 million years. However, we may see it in our lifetime.” says marine geologist Jochen Knies.

The extent of sea ice cover in Arctic was much less than it is today between four and five million years ago. The maximum winter extent did not reaching its current location until around 2.6 million years ago. This new knowledge can now be used to improve future climate models.

“We have not seen an ice free period in the Arctic Ocean for 2,6 million years. However, we may see it in our lifetime. The new IPCC report shows that the expanse of the Arctic ice cover has been quickly shrinking since the 70-ies, with 2012 being the year of the sea ice minimum”, Jochen Knies.

He is marine geologist at the Geological Survey of Norway (NGU) and Centre for Arctic Gas Hydrate, Climate and Environment, UiT The Arctic Univeristy of Norway.

In an international collaborative project, Jochen Knies has studied the trend in the sea ice extent in the Arctic Ocean from 5.3 to 2.6 million years ago. That was the last time the Earth experienced a long period with a climate that, on average, was warm before cold ice ages began to alternate with mild interglacials.

Fossils reveal past sea ice extent

“When we studied molecules from certain plant fossils preserved in sediments at the bottom of the ocean, we found that large expanses of the Arctic Ocean were free of sea ice until four million years ago,” Knies tells us.

“Later, the sea ice gradually expanded from the very high Arctic before reaching, for the first time, what we now see as the boundary of the winter ice around 2.6 million years ago ,” says Jochen Knies, who is also attached to CAGE, the Centre for Arctic Gas Hydrate, Environment and Climate at the University of Tromsø, the Arctic University of Norway.

Arctic Ocean likely to be completely free of sea ice

The research is of great interest on the international stage because present-day global warming is strongly tied to a shrinking ice cover in the Arctic Ocean. By the end of the present century, the Arctic Ocean seems likely to be completely free of sea ice, especially in summer.

This may have major significance for the entire planet ‘s climate system. Polar oceans , their temperature and salinity, are important drivers for world ocean circulation that distributes heat in the oceans. It also affects the heat distribution in the atmosphere. Trying to anticipate future changes in this finely tuned system, is a priority for climate researchers. For that they use climate modeling , which relies on good data.

“Our results can be used as a tool in climate modelling to show us what kind of climate we can expect at the turn of the next century. There is no doubt that this will be one of many tools the UN Climate Panel will make use of, too. The extent of the ice in the Arctic has always been very uncertain but, through this work, we show how the sea ice in the Arctic Ocean developed before all the land-based ice masses in the Northern Hemisphere were established,” Jochen Knies explains.

Seabed samples from Spitsbergen

A deep well into the ocean floor northwest of Spitsbergen was the basis for this research. It was drilled as part of the International Ocean Drilling Programme, (IODP), to determine the age of the ocean-floor sediments in the area. Then, by analysing the sediments for chemical fossils made by certain microscopic plants that live in sea ice and the surrounding oceans, Knies and his co-workers were able to fingerprint the environmental conditions as they changed through time.

“One thing these layers of sediment enable us to do is to “read” when the sea ice reached that precise point,” Jochen Knies tells us.

The scientists believe that the growth of sea ice until 2.6 million years ago was partly due to the considerable exhumation of the land masses in the circum-Arctic that occurred during this period. “Significant changes in altitudes above sea level in several parts of the Arctic, including Svalbard and Greenland, with build-up of ice on land, stimulated the distribution of the sea ice,” Jochen Knies says.

“In addition, the opening of the Bering Strait between America and Russia and the closure of the Panama Cannel in central America at the same time resulted in a huge supply of fresh water to the Arctic, which also led to the formation of more sea ice in the Arctic Ocean,” Jochen Knies adds.

All the large ice sheets in the Northern Hemisphere existed around 2.6 million years ago.

Prehistoric conflict hastened human brain’s capacity for collaboration, study says

2

Warfare not only hastened human technological progress and vast social and political changes, but may have greatly contributed to the evolutionary emergence of humans’ high intelligence and ability to work together toward common goals, according to a new study from the National Institute for Mathematical and Biological Synthesis (NIMBioS).

How humans evolved high intelligence, required for complex collaborative activities, despite the various costs of having a big brain has long puzzled evolutionary biologists. While the human brain represents only about two percent of the body’s weight, it uses about 20 percent of the energy consumed. Other costs of having a large brain include a need for extended parental care due to a long growth period, difficulties giving birth to larger-headed babies, and some mental illnesses associated with brain complexity. So how did the human brain evolve to become so large and complex?

Another long-running question is how did humans evolve strong innate preferences for cooperative behavior, as cooperative behavior is vulnerable to exploitation by cheaters and “free-riders.” A free-rider doesn’t contribute or cooperate and thereby undermines the effectiveness of the group’s collaborative effort, something scientists call “the collective action problem.” Thus, collaborative behavior is expected to be rare, and indeed, in animals it is typically limited to close relatives. Humans, however, are a unique species where collaboration is widespread and not limited to relatives.

In the new study published in the Journal of Royal Society Interface, lead author Sergey Gavrilets, a professor of ecology and evolutionary biology and mathematics at the University of Tennessee, Knoxville, and NIMBioS associate director for scientific activities, developed a mathematical model that offers answers to both evolutionary puzzles.

The model shows that intelligence and cooperative behavior can co-evolve to solve the problem of collective action in groups and to overcome the costs of having a large brain.

The research points to the types of collective actions that are most effective at hastening collaboration. According to the model, collaborative ability evolves easiest if there is direct conflict or warfare between groups, what Gavrilets calls “us vs. them” activities. In contrast, collective activities, such as defending against predators or hunting for food, which Gavrilets calls “us vs. nature” activities, are much less likely to result in a significant increase in collaborative abilities.

The study also predicts that if high collaborative ability cannot evolve, perhaps for example because the costs of having a big brain are too high, the species will harbor a small proportion of individuals with a genetic predisposition to perform individually-costly but group-beneficial acts.

In addition, the model challenges influential theories on when large-game hunting and within-group coalitions first appeared in humans. Some scientists say that within-group coalitions and collaborative hunting came first and then subsequently created conditions for the evolution of collaboration in between-group conflicts. Yet, Gavrilets’ model shows the opposite: that collaboration in between-group fighting preceded both within-group coalitions and collaborative hunting.

“Our ability to effectively collaborate with others is largely responsible for what our species came to be. The big question is how this ability first evolved when there are large metabolic and physiological costs related to human brain size and when collaboration can be easily undermined by free riders. The model offers an answer which emphasizes the role of between-group conflicts in shaping unique human features,” Gavrilets said.

OU Professor and team discover first evidence of milk consumption in ancient dental plaque

0

Led by a University of Oklahoma professor, an international team has uncovered the very first evidence of milk consumption in the ancient dental calculus – a mineralised dental plaque – of humans in Europe and western Asia. The team discovered direct evidence of milk consumption preserved in human dental plaque from the Bronze Age to the present day.

“The study has far-reaching implications for understanding the relationship between human diet and evolution,” said Christina Warinner, professor in the OU Department of Anthropology. “Dairy products are a very recent, post-Neolithic dietary innovation, and most of the world’s population is unable to digest lactose, often developing the symptoms of lactose intolerance.” Warinner headed a group of researchers from the universities of York and Copenhagen, and the University College of London.

Comprehending how, where and when humans consumed milk products is a crucial link between human consumption and their livestock. The novel research provides direct protein evidence that the milk of all three major dairy livestock – cattle, sheep and goats – has been consumed by human populations for at least 5,000 years. This validates previous evidence for milk fats identified on pottery and cooking utensils in early farming communities.

“The discovery of milk proteins in human dental calculus will allow scientists to unite these lines of evidence and compare the genetic traits and cultural behaviours of specific individuals who lived thousands of years ago,” says Warinner.

Post-medieval Polish buried as potential ‘vampires’ were most probably local

0

Potential vampires in the 17th-18th century buried with rocks and sickles to ward off evil.

Potential ‘vampires’ buried in northwest Poland with sickles and rocks across their bodies were most probably local and not immigrants to the area, according to a study published yesterday in the open-access journal PLOS ONE by Lesley Gregoricka from University of South Alabam and colleagues.

In northwest Poland, apotropaic funerary rites – a traditional practice intended to prevent evil – occurred throughout the 17th-18th c. AD. Those of the dead considered at risk for becoming vampires for various reasons were given specific treatment, and investigating these burial practices may provide valuable information into community cultural and social practices, as well as the social identities of people living in the area at the time.

Excavations at a cemetery in northwestern Poland have unveiled six unusual graves, with sickles across the bodies or large rocks under the chins of select individuals, amidst hundreds of normal burials. In order to obtain a better understanding as to whether the bodies selected for aprotropaic burial rites were local or non-local immigrants, the authors of this study tested permanent molars from 60 individuals, including six “special” or deviant burials, using radiogenic strontium isotope ratios from archaeological dental enamel. They then compared the results to strontium isotopes of local animals.

The authors discovered that those in deviant burials appear to be a predominantly local population, with all individuals buried as potential vampires exhibiting local strontium isotope ratios.

These data indicate that those targeted for apotropaic practices were not likely migrants to the area, but rather, local individuals whose social identity or manner of death likely marked them with suspicion in some other way.

The authors imply one alternative explanation behind these apotropaic burials may be the cholera epidemics that were dominant in Eastern Europe during the 17th century, as the first person to die from an infectious disease outbreak was presumed more likely to return from the dead as a vampire.

“People of the post-medieval period did not understand how disease was spread, and rather than a scientific explanation for these epidemics, cholera and the deaths that resulted from it were explained by the supernatural – in this case, vampires,” said Dr. Gregoricka.

Ancient rock art discovery across Asia

0

Latest research on the oldest surviving rock art of Southeast Asia shows that the region’s first people, hunter-gatherers who arrived over 50,000 years ago, brought with them a rich art practice.

Published this week in the archaeological journal Antiquity, the research shows that these earliest people skilfully produced paintings of animals in rock shelters from southwest China to Indonesia. Besides these countries, early sites were also recorded in Thailand, Cambodia and Malaysia.

Griffith University Chair in Rock Art Professor Paul Taçon led the research which involved field work with collaborative international teams in rugged locations of several countries.

The oldest paintings were identified by analysing overlapping superimpostions of art in various styles as well as numerical dating. It was found that the oldest art mainly consists of naturalistic images of wild animals and, in some locations, hand stencils.

caveart2

The research shows that 35,000 – 40,000 year old dates for some rock art in Sulawesi, Indonesia announced in October by Griffith University Senior Research Fellow Maxime Aubert is not an anomaly. Instead, the practice was widespread across the region.

Professor Taçon said that, “As with the early art of Europe, the oldest Southeast Asian images often incorporated or were placed in relation to natural features of rock surfaces.

“This shows a purposeful engagement with the new places early peoples arrived in for both symbolic and practical reasons.

“Essentially, they humanised landscapes wherever they went, transforming them from wild places to cultural landscapes. This was the beginning of a process that continues to this day.”

But unlike in Europe, the oldest surviving rock art of Southeast Asia is more often found in rock shelters rather than deep caves, suggesting experiences in deep caves cannot have been their inspiration as has long been argued for Europe.

“This significantly shifts debates about the origins of art-making and supports ideas that this fundamental human behaviour began with our most ancient ancestors in Africa rather than Europe.

“The research supports the idea suggested by the early Indonesian rock art dates that modern humans brought the practice of making semi-permanent images in rocky landscapes to Europe and Asia from Africa,’’ Professor Taçon said.

These results have implications not only for our understanding of Southeast Asian and European rock art but also Australian, because in Kakadu-Arnhem Land and other parts of northern Australia the oldest surviving rock art also consists of naturalistic animals and stencils.

Thus the practice of making these sorts of designs may have been brought to Australia at the time of initial colonisation, but it may alternatively have been independently invented or resulted from as yet unknown forms of culture contact.

All three possibilities are equally intriguing. New investigations in both northern Australia and Southeast Asia are currently being planned.

Bronze Age dirk dagger used as doorstop saved with grant from the NHMF

1

A rare Middle Bronze Age weapon, one of only six known from Europe, has been saved for the nation with a grant of almost £39,000 from the National Heritage Memorial Fund (NHMF).

The award, made to Norwich Castle Museum and Art Gallery, has allowed the Rudham Dirk, a ceremonial dagger, to come into public ownership to be placed on display for visitors to enjoy.

The Dirk was discovered twelve years ago, when it was ploughed up in a field in East Rudham, north Norfolk. Its significance unknown at that time, it was subsequently used as a doorstop until it was identified in 2013.

It is incredibly rare and only six examples of this type of dirk are known in Europe: two from France, two from Holland and now two from Britain. Intriguingly, the British parallel was also found in Norfolk, at Oxborough in 1988, and is now in the British Museum.

What makes the Rudham Dirk particularly distinctive is its monumental size. At approximately 68cms long it is about three times the size of a normal Bronze Age dirk and so large and heavy it is completely impractical as a weapon.

With a blunt blade that was never sharpened and no rivet holes for a handle, the Dirk was deliberately designed as a ceremonial weapon. This is almost certainly the reason why it was found bent in half, deliberately folded as part of the object’s ritual ‘destruction’ before its burial, a practice well known from Bronze Age metalwork.

Dr Tim Pestell, Senior Curator of Archaeology at Norwich Castle said: “We are delighted to have secured such an important and rare find as this, which provides us with insights into the beliefs and contacts of people at the dawn of metalworking. Through its display we hope to bring residents and visitors to Norfolk closer to the remarkable archaeology of our region and stories of our ancient past.”

Carole Souter, Chief Executive of NHMF, said: “This is great news! The Rudham Dirk is a fascinating piece of our heritage that offers real insight into how our Bronze Age ancestors lived. Our trustees felt it vital that it be secured for the nation and remain in Norfolk where local people can enjoy it and explore its connection to the area.”

After some years as a doorstop, the dirk was reviewed by Norfolk’s Identification and Recording Service, which runs the county’s Portable Antiquities Scheme where it was dated and identified as an artefact of incredible importance. Negotiations were subsequently opened between the landowner and Norwich Castle Museum and Art Gallery and a final sale price of £40,970 agreed. Grants from the National Heritage Memorial Fund and the Norfolk and Norwich Archaeological Society have enabled the dirk to be secured for the nation.

Scientific methods shed new light on evolution of kinship patterns

0

New biological methods used to trace the evolutionary history of kinship patterns shed new light on how societies developed as farming spread across the globe during the Neolithic, according to new research by a UCL-led international team.

Kinship is the web of social relationships that underlie human society, with lines of descent determining how wealth, land and position are inherited across the generations.

The paper, published today in PNAS, demonstrates the use of “virtual archaeology”  or phylogenetic techniques that enable the study of evolutionary relationships among groups using language trees in reconstructing the ancestral state of kinship in Bantu cultures in Africa.

The research shows how inheritance and residence rules co-evolved as farming spread throughout sub-Saharan Africa, with the findings questioning current theories suggesting that residence rules were the primary driver of all other human social structures, dictating lines of descent and where people chose to live and settle.

The use of phylogenetics, a method adapted from evolutionary biology, opens up many possibilities in the social sciences as an alternative way of reconstructing the evolutionary history of cultural and social traits.

Lead author Dr Kit Opie (UCL Anthropology) said: “Kinship a big issue in anthropology, but current methods used to piece together historical social hierarchies, for example by looking at linguistic reconstructions or archaeological evidence, can be problematic.

“The use of phylogenetics, a method adapted from evolutionary biology, opens up many possibilities in the social sciences as an alternative way of reconstructing the evolutionary history of cultural and social traits. The Bayesian analysis involved is similar to the algorithms used by Google’s search engines and this is the first time the technique has been applied to Bantu cultural change.

“The implications in bringing these kind of biological approaches into the social sciences are very significant. It feels like we’re at the start of a new era for the social sciences.”

*Bantu peoples or cultures is used as a general label for the 300–600 populations in Africa who speak Bantu languages and inhabit a geographical area stretching east and southward from Central Africa across the African Great Lakes region down to Southern Africa.

Evidence of domestic cereals in Sudan as early as 7,000 years ago

0

Humans in Africa already exploited domestic cereals 7,000 years ago and thus several centuries earlier than previously known.

A research team from Barcelona, Treviso, London and Kiel was successful in verifying ancient barley and wheat residues in grave goods and on teeth from two Neolithic cemeteries in Central Sudan and Nubia.

Dr. Welmoed Out of the Graduate School “Human Development in Landscapes” in Kiel was involved in the investigation. “With our results we can verify that people along the Nile did not only exploit gathered wild plants and animals but even crops of barley and wheat.”

These were first cultivated in the Middle East about 10,500 years ago and spread out from there to Central and South Asia as well as to Europe and North Africa – the latter faster than expected. “The diversity of the diet was much greater than previously assumed,” states Out and adds: “Moreover, the fact that grains were placed in the graves of the deceased implies that they had a special, symbolic meaning.”

The research team, coordinated by Welmoed Out and the environmental archaeologist Marco Madella from Barcelona, implemented, among other things, a special high-quality light microscope as well as radiocarbon analyses for age determination. Hereby, they were supported by the fact that mineral plant particles, so-called phytoliths, survive very long, even when other plant remains are no longer discernible. In addition, the millennia-old teeth, in particular adherent calculus, provide evidence on the diet of these prehistoric humans due to the starch granules and phytoliths contained therein.

The Graduate School Human Development in Landscapes (GSHDL) was established in 2007 within the framework of the federal and state supported Excellence Initiative. In this context, scholars in the humanities and the natural sciences are involved in research projects on the complex relationship between society, culture and the environment. Prehistoric societies are particularly investigated as exemplary examples.

Vultures evolved an extreme gut to cope with disgusting dietary habits

0

How is it that vultures can live on a diet of carrion that would at least lead to severe food-poisoning, and more likely kill most other animals?

This is the key question behind a recent collaboration between a team of international researchers from Denmark’s Centre for GeoGenetics and Biological Institute at the University of Copenhagen, Aarhus University, the Technical University of Denmark, Copenhagen Zoo and the Smithsonian Institution in the USA. An “acidic” answer to this question is now published in the scientific journal Nature Communications.

When vultures eat lunch they happily strip the rotting carcasses they find back to the bone. And if, however, the animal’s hide is too tough to easily pierce with their beak, they don’t hesitate to enter it using other routes, among them the back entrance – so to speak: via the anus. Although their diet of meat that is both rotting and liberally contaminated with feces would likely kill most other animals, they are apparently immune to the cocktail of deadly microbes within their dinner such as Clostridia, Fuso- and Anthrax-bacteria.

– To investigate vultures’ ability to survive eating this putrid cocktail, we generated DNA profiles from the community of bacteria living on the face and gut of 50 vultures from the USA. Our findings enable us to reconstruct both the similarities, and differences, between the bacteria found in turkey vultures and black vultures, distributed widely in the Western Hemisphere. Apparently something radical happens to the bacteria ingested during passage through their digestive system, says Lars Hestbjerg Hansen, a professor at Aarhus University who together with PhD-student Michael Roggenbuck lead the study while he was at the University of Copenhagen.

From head to gut

On average, the facial skin of vultures contained DNA from 528 different types of micro-organisms, whereas DNA from only 76 types of micro-organisms were found in the gut. Michael Roggenbuck explains:

– Our results show there has been strong adaptation in vultures when it comes to dealing with the toxic bacteria they digest. On one hand vultures have developed an extremely tough digestive system, which simply acts to destroy the majority of the dangerous bacteria they ingest. On the other hand, vultures also appear to have developed a tolerance towards some of the deadly bacteria – species that would kill other animals actively seem to flourish in the vulture lower intestine.

These observations raise the question as to whether the Clostridia and Fusobacteria in the gut simply out-compete the other bacteria but don’t confer any benefit to the vulture, or in contrast, if their presence actually confers dietary advantages for the vultures. The team’s results suggest that it’s probably a bit of both – while other microorganisms are likely out-competed by the surviving bacteria, the vultures also receive a steady stream of important nutrients when the bacteria break down the carrion. Of broader significance, Gary Graves of the Smithsonian Institution’s National Museum of Natural History observed:

– The avian microbiome is terra incognita but it is not unreasonable to suppose that the relationship between birds and their microbes has been as important in avian evolution as the development of powered flight and song.

Woolly Mammoth autopsy results revealed

0

In May 2013, a team of international scientists unearthed the remains of a mammoth in the furthest reaches of northern Siberia.

This discovery of a mammoth with the best preserved flesh yet (three legs, most of the body, some of the head and even the trunk survived in extraordinary condition) has quickened the pace of one of the most ambitious and controversial projects in science – the cloning of the woolly mammoth. This one is unlike any mammoth found before; when it was dug out of the permafrost, a dark red liquid oozed from the frozen body. Speculation is rife – could the liquid be mammoth blood? And, controversially, does the freshness of the mammoth’s flesh mean that a clone is now achievable?

The autopsy of the animal (nicknamed ‘Buttercup’ by the team) and analysis of its tusks reveal the life story of this mammoth in forensic detail. Part of the autopsy team was Dr Tori Herridge from London’s Natural History Museum; a palaeobiologist, she possesses an in-depth knowledge of mammoth anatomy.

  • Carbon dating of the mammoth’s flesh revealed that she walked the earth 40,000 years ago.
  • Discovering the presence of haemoglobin confirmed that the dark red liquid is definitely blood.
  • The mammoth was female and analysis of her tusks indicates approximately eight successful calving events and one calf lost. Females grew their tusks once they got into their calf-bearing years, at rates that were very much dependent on where they were in a calving cycle. Tusks grew more slowly when a female mammoth was pregnant and lactating.
  • From her teeth, Dr Herridge was also able to estimate that the mammoth was in its fifties when it died. Mammoths and elephants have similar teeth and through their lives the molars are replaced six times. When the last set wears out, they starve and die. Dr Herridge’s examination of the teeth revealed dental abnormalities, indicating that she wasn’t able to chew her food correctly, which may explain gobstopper-sized stones found in the gut.
  • Despite their reputation for being enormous, this mammoth was not much larger than an Asian elephant.
  • She met her end by becoming trapped in a peat bog and being eaten alive by predators from the rear end.

These new findings will be revealed for the first time in a Channel 4 documentary to be screened on Sunday 23 November (Woolly Mammoth – The Autopsy, 8pm). Alongside this compelling insight into the life of a Siberian mammoth 40,000 years ago, the programme enjoys exclusive access to the leading mammoth de-extinction programmes happening right now in the United States and South Korea.

Dr Tori Herridge, palaeobiologist at the Natural History Museum, says: “As a palaeontologist, you normally have to imagine the extinct animals you work on. So actually coming face-to-face with a mammoth in the flesh, and being up to my elbows in slippery, wet, and –frankly- rather smelly mammoth liver, counts as one of the most incredible experiences of my life. It’s up there with my wedding day. The information gleaned from Buttercup’s autopsy about her life and death, and the future discoveries that will come from analyses of her muscles and internal organs, will add to our understanding of these magnificent Ice Age beasts.”

Flower links civil war, natural history and ‘The Blood Of Heroes’

0

On August 14, 1864, in a Union Army camp in Georgia, a captain from Wisconsin plucked a plant, pressed it onto a sheet of paper, wrote a letter describing the plant as “certainly the most interesting specimen I ever saw,” and sent it with the plant to a scientist he called “Friend” in Wisconsin.

“It was growing outside my tent and notwithstanding the noise of 500 pieces of artillery flourished,” wrote John Cornelius McMullen, “and seemed to repose as sweetly at night as if its native heath was not disturbed by the tread of hostile armies.”

The captain-collector was clearly literate, even poetic.

The scientist, Increase Lapham (1811-1875), is today considered the founder of natural history in Wisconsin. A geologist, botanist and historian, he is the subject of a new biography, “Studying Wisconsin: The Life of Increase Lapham,” published by the Wisconsin Historical Society.

And but for that book, a plant specimen that Wisconsin State Herbarium director Ken Cameron calls “perhaps our most astonishing of all” might never have surfaced from the 1.2 million dried plants in the collection on the University of Wisconsin-Madison campus.

Because Lapham’s personal plant collection actually founded the herbarium more than 160 years ago, authors Paul G. Hayes and Martha Bergland held a reading of the biography at the herbarium, located in the Department of Botany, in October. In preparation, the herbarium put on display some of Lapham’s original specimens, including the 150-year-old sheet holding Cassia obtusifolia (“Wild Sensitive Plant”). “We started to read the letter attached to it,” says Cameron. “The sender described the flower as ‘stained with the blood of heroes,’ and that really caught our eyes!”

Who was this lyrical captain? John Cornelius McMullen was apparently born in Delaware or New Jersey and graduated from Lawrence University in Appleton, Wisconsin. He entered the First Wisconsin Regiment on Sept. 16, 1861 from Sheboygan Falls, fought with them and was wounded, through Kentucky, Tennessee and northern Georgia under General Sherman.

The plant and the letter were both a surprise, says co-author Bergland, a retired English teacher from Glendale, Wisconsin. “I did not know about it until we showed up to do the reading. It’s wonderful that it was discovered, but I think Lapham would have had a very ambivalent response to such a letter. He was a Quaker, a pacifist – did not want anything to do with war. But he was very supportive … of veterans, especially wounded veterans.”

In his letter, McMullen laid out the circumstances of the First Wisconsin Regiment. “We are now in plain view of the great commercial city of Georgia. My company are in the front line of works only a half mile from town and while I write shot and shells are constantly passing over us. It may be some days before Atlanta falls but in the end it must yield for the best army in the world are thundering at its gate.”

Despite his surroundings – or perhaps because of them – McMullen concluded on a sentimental note: “This flower was moistened by the blood of heroes, for Wisconsin men have died where it was plucked.”

McMullen worked for the federal government in Tennessee after the war, and may have moved to Oakland, California, where a man of the same name and general age was described as running a bank.

An herbarium is a venerable repository of pressed and dried plant specimens that serves as a reference library for plants. Although they are now being used scientifically in ways they never imagined a century ago, Cameron, also a professor of botany at UW-Madison, says this mystery, worthy of Antiques Roadshow, demonstrates another side of these collections.

“This specimen shows that our collection also has value for understanding history and bridging the sciences with the humanities. This comes down from a time when all well-educated people had a different view of nature and collecting plants was a common activity. There are treasures in the collection that we don’t know we are sitting on.”

Excavations of the Pafos Agora Project 2014

0

The Department of Antiquities, Ministry of Communications and Works, announces the completion of the fourth season of excavations within the framework of the Pafos Agora Project, which aims to explore and study the Agora of the ancient city of Nea Pafos, the capital of Cyprus in the Hellenistic and Roman periods.

The 2014 field work took place between August 8 and October 10th. The team, which was led by Professor Ewdoksia Papuci-Władyka, comprised nearly 60 persons (20 staff, 15 student trainers, 23 volunteers).

The campaign’s aim was not only to excavate and provisionally study the uncovered material, but also to conduct preservation work performed by members of the Institute’s staff and to implement new, non-invasive research techniques (already partly tested during the 2013 season).

The non-invasive research was conducted by specialists from the AGH University of Science and Technology in Krakow (Laser scanning of trenches) and the J. Kochanowski University in Kielce (Georadar prospection). Thus, the project has an interdisciplinary character.

The field work took place in all three trenches although in Trench II it was limited to the exploration of the well in Room 13, which had already began in the previous season during which it had been interpreted as a cistern. However, the excavation in 2014 clearly showed that this feature is definitely a well. The well was excavated to a depth of 7 metres, and at the depth of 5.95m, the ground water table was reached, affecting the exploration significantly: the team is deeply indebted to the local fire brigade for their assistance in this matter.

The well was filled-in with rich movable material and earth. Firstly, pottery of different categories: fine wares, plain wares, cooking ware and transport amphorae (some of which bear stamps). The team also found terracotta figurines, coins and metal objects. Amongst the metal objects were three very interesting sling bullets, two of which were decorated with a relief depicting scorpions and the third with a representation of thunderbolt.

Based on the pottery and the amphorae stamps, it can be stated that the material of the well constitutes a homogeneous, closed late Hellenistic deposit, dated from the late 2nd to the mid-1st centuries BC. From an architectural point of view, the construction of the well is very closely connected with the first phase of the stylobate of the east portico of the Agora, and so the initial date of this portico should probably be moved back to an even earlier date i.e. to Hellenistic times. However, it should be noted that this hypothesis will need to be confirmed with the study of the material, particularly the coins numbering almost 60, have been studied.

Large-scale works were undertaken in Trench I, situated in the central part of the Agora square. The excavations cleared and enlarged squares traced and partly excavated by K. Nicolaou in the 1970’s. These squares were combined with the current excavation squares, excavated within Trench I in 2011. Nicolaou had stated that it was likely that an altar had been uncovered. The Polish team proposes that this was not an altar but part of a large, very well constructed building, probably a temple with an East-West orientation.

Furthermore, the team suggests that the type of wall construction (the so-called compartment type), which is very characteristic of the Ptolemaic period, and the excavated moveable finds (mainly pottery) point to a Hellenistic date. It seems that the building/temple was in use for a long period and was rebuilt several times. In close vicinity to this building – to the south – a large pit was discovered filled-in with pottery and numerous terracotta figurine fragments of which the latest can be dated to the late 2nd and early 1st centuries BC. The building was perhaps rebuilt at this time and the material that was of no use was thrown into the pit.

In Trench III, structures that were discovered in 2013 were further investigated. In addition, the trench was extended to the south aiming to uncover a possible continuation of walls found in 2013. As a result, part of a large building, erected on cut bedrock, was uncovered composed of at least two rooms.

This building was built before the erection of the south portico of the agora. A preliminary analysis of the pottery indicates that that the building was possibly erected during the late Classical/Early Hellenistic period, i.e. in the early days of the city, and that it was also used after the erection of the south portico, during the first phase of the agora. The final period of the building’s use seems to have been the 2nd and 1st c. BC. However, the exact function of the building remains unclear. In Trench III 12 new structures were explored, among which are five walls, two floors and one channel.

As of 2013, part of the project’s aims is the development of a new system of documentation titled, “The Archaeological and Archaeometric Information System for the Pafos Agora Project” (AIS for PAP). This system will link standard archaeological documentation with Digital Elevation Model (DEM), correlated with the documentation database and coupled with orthophotomap running under the Geographical Information System (GIS).

Oxford team shed light on Philae obelisk

1

History was made this month as the robotic Philae lander completed the first controlled touchdown on a comet. The European Space Agency-led project was set up to obtain images of a comet’s surface and help scientists to understand what a comet is made of.

The lander and the Rosetta probe which transported it were named after two of the objects which were crucial in deciphering Egyptian hieroglyphs: the Rosetta stone and the Philae obelisk. Back on earth, a team from the Centre for the Study of Ancient Documents in Oxford’s Classics Faculty are using a powerful digital imaging system, Reflectance Transformation Imaging (RTI), to study the inscriptions on the obelisk more closely than ever before.

‘The Centre is home to an exciting new study of Ptolemaic inscriptions (a Hellenistic kingdom based in Egypt  in the fourth to first centuries BC) and the Philae obelisk and Rosetta stone are the jewels of the crown of that corpus,’ said Dr Jane Masséglia of the Centre for the Study of Ancient Documents (CSAD). Both include inscriptions in Egyptian hieroglyphs and ancient Greek, but while the Rosetta stone’s inscriptions are direct translations of one another,  the inscriptions on the obelisk are different.

‘Both ancient Greek and Egyptian scripts on the obelisk mention the names  ‘Ptolemy’ and ‘Cleopatra’ which helped nineteenth-century scholars  to use their knowledge of ancient Greek to translate some of the Egyptian hieroglyphs.’

The obelisk is one of two found at Philae in Upper Egypt in 1815. It was acquired by William John Bankes, who brought it to his estate at Kingston Lacy in Dorset, now owned by the National Trust.

‘After 200 years being battered by the English weather in Dorset, and because of the naturally speckled pink and black granite, it’s difficult for the human eye to read all of the inscriptions,’ said Dr Masséglia.

‘RTI has let us take images of the obelisk in such a way that can remove the colour. It produces a computer reconstruction of the surface of the object, based on reflections of light, so we have been able to produce clearer images of the inscriptions than ever before.’

The Oxford team is currently analysing the images taken from the obelisk but they have already made some findings about the inscriptions. ‘We have an early nineteenth-century drawing of the obelisk, made just before it was announced that hieroglyphs had been deciphered,’ said Dr Masséglia. ‘Now that we have the high-quality RTI images, we can say that whoever produced that drawing really knew what they were doing. It’s a very good record for such an early date and may even be the very document that was sent by Bankes to Champollion, the man credited with the eventual decipherment of hieroglyphs.

‘Our next project is to complete the reading of the ancient Greek inscription on the base, which has never been entirely legible, not even when Bankes first saw it in Philae. We can see that it records a petition from the priests of Philae to Ptolemy VIII and his two wives, asking to be exempted from tax. But large sections of the text are badly worn, and RTI is the technology to help us complete the picture. It’s very exciting.’

CSAD hosts several research projects that are using RTI to investigate important areas of classical scholarship. Projects include studying Roman letters from Vindolanda near Hadrian’s Wall, ancient curse tablets from Roman Gloucestershire, and a new study of the Latin inscriptions in the Ashmolean Museum.

‘The technology is so exciting because we can apply it to so many different ancient artefacts which cannot be fully understood by the human eye,’ said Dr Masséglia. ‘Our RTI expert, Ben Altshuler, has also been working with colleagues in the Beazley archive to study microscopic marks on ancient gems and even Greek vases.

‘It’s so good, it can even show which line was painted over which, and see the marks of preparatory drawings underneath the glaze. You can imagine what a difference this could make to someone’s experience of archaeology. Whether at the museum or sitting at home, they could use the RTI software to examine an object in minute detail, and see more than they ever could with the naked eye.’
