UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in the Earth’s climate in the past 400 million years.
If Pleistocene megafauna — mastodons, mammoths, giant sloths and others — had not become extinct, humans might not be eating pumpkin pie and squash for the holidays, according to an international team of anthropologists. “It’s been suggested before and I think it’s a very reasonable hypothesis, that wild species of
At the end of the Pleistocene mammoths of Northern Eurasia used to experience chronic mineral hunger.
The extinction of large herbivores such as mammoths could explain massive prehistoric changes in vegetation and landscape structure.
Radiocarbon analysis of the decline and extinction of large mammals in the Americas lends support to the idea that hunting by humans led to the animals’ demise — and backs the generally accepted understanding of when humans arrived in, and how they colonized, the Western Hemisphere.
UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago — 300 million years earlier than previous research suggested.
New research from the University of Georgia department of psychology gives researchers a unique glimpse at how humans develop an ability to use tools in childhood while nonhuman primates–such as capuchin monkeys and chimpanzees–remain only occasional tool users.
The Royal Research Ship Discovery has completed her first year of research. Over a series of nine research expeditions, scientists studied the seasonal events taking place in UK shelf waters throughout the year.
Scientists have long theorized that the long neck of modern-day giraffes evolved to enable them to find more vegetation or to develop a specialized method of fighting.
A team of scientists led by Dr Pierre-Marc Delaux (John Innes Centre / University of Wisconsin, Madison) has solved a long-running mystery about the first stages of plant life on earth.
Discoveries about how the human brain contributes to our success – both as a species and as individuals – are among the first fruit of projects funded under the National Institutes of Health BRAIN Initiative program as well as the Human Connectome Project.
About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it, providing what researchers believe may be the oldest evidence on Earth of a dreaded and historic killer – an ancient strain of the bubonic plague.
Researchers from the University of Bristol describe how they used radiocarbon measured in deep-sea fossil corals to shed light on carbon dioxide (CO2) levels during the Earth’s last deglaciation.
For the first time, an international team of researchers has sequenced the complete genomes of eleven Przewalski’s horses, including all of the founding lineages and five historical, museum specimens dating back more than a century.
A first draft of the “tree of life” for the roughly 2.3 million named species of animals, plants, fungi and microbes has been released, and two University of Michigan biologists played a key role in its creation.
The African clawed frog is tongue-less, has long, curvy toes and eyes that are perched on top of its head, but that’s not all that’s odd about it.
Why do certain body shape and size relationships remain consistent over long periods? One such example is found in flies, where small wings are normally rounder than large wings.
In the last 30,000 years there was, at times, more mixing in the Southern Ocean than previously thought.
Snowpack in California’s Sierra Nevada in 2015 was at the lowest level in the past 500 years, according to a new report led by University of Arizona researchers.
The globe’s forests have shrunk by three per cent since 1990 – an area equivalent to the size of South Africa – despite significant improvements in conservation over the past decade.
In ongoing research to record the interaction of environment and evolution, a team led by University of California, Riverside biologist David Reznick has found new information illustrating the evolution of a population of guppies.
An international research team led by University of Otago scientists has documented prehistoric “sanctuary” regions where New Zealand seabirds survived early human hunting.
