Ice Age paleontologist Prof. Dr. Ralf-Dietrich Kahlke of the Senckenberg Research Station for Quaternary Paleontology in Weimar recorded the maximum geographic distribution of the woolly mammoth during the last Ice Age and published the most accurate global map in this regard.
The second ice age during the Cryogenian period was not followed by the sudden and chaotic melting-back of the ice as previously thought, but ended with regular advances and retreats of the ice, according to research published by scientists from the University of Birmingham in the journal Nature Geoscience.
Humans are just one of many predators in this world, but a new study highlights how their intense tendency to target and kill adult prey, as well as other carnivores, sets them distinctly apart from other predators. As humans kill other species in their reproductive prime, there can be profound
Indiana University paleobotanist David Dilcher and colleagues in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on Earth.
Early humans were the dominant cause of the extinction of a variety of species of giant beasts, new research has revealed.
Hawai’i has been called the “extinction capital of the world.” But, with the exception of the islands’ birds, there has until now been no accurate assessment of the true level of this catastrophic loss.
Documents dating back to the 16th Century provide a unique insight into one of Darwin’s landmark studies – according to new research from the University of East Anglia.
An intriguing study involving walking stick insects led by the University of Sheffield in England and the University of Colorado Boulder shows how natural selection, the engine of evolution, can also impede the formation of new species.
When life on Earth began nearly 4 billion years ago, long before humans, dinosaurs or even the earliest single-celled forms of life roamed, it may have started as a hiccup rather than a roar: small, simple molecular building blocks known as “monomers” coming together into longer “polymer” chains and falling apart in the warm pools of primordial ooze over and over again.
As grasses grew more common in Africa, most major mammal groups tried grazing on them at times during the past 4 million years, but some of the animals went extinct or switched back to browsing on trees and shrubs, according to a study led by the University of Utah.
From an early age, human infants are able to produce vocalisations in a wide range of emotional states and situations – an ability felt to be one of the factors required for the development of language. Researchers have found that wild bonobos (our closest living relatives) are able to vocalize in a similar manner. Their findings challenge how we think about the evolution of communication and potentially move the dividing line between humans and other apes.
Researchers led by the University of Cambridge have found the earliest example of reproduction in a complex organism. Their new study has found that some organisms known as rangeomorphs, which lived 565 million years ago, reproduced by taking a joint approach: they first sent out an ‘advance party’ to settle in a new area, followed by rapid colonisation of the new neighbourhood. The results, reported today in the journal Nature, could aid in revealing the origins of our modern marine environment.
The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years.
Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps).
The light-sensing molecules that tell plants whether to germinate, when to flower and which direction to grow were inherited millions of years ago from ancient algae, finds a new study from Duke University.
New research reveals that some of the earliest civilizations in the Middle East and the Fertile Crescent may have been affected by abrupt climate change. These findings show that while socio-economic factors were traditionally considered to shape ancient human societies in this region, the influence of abrupt climate change should
Rapid phases of warming climate played a greater role in the extinction of megafauna in the Late Pleistocene than did human activity, a new study shows.
New research has revealed abrupt warming, that closely resembles the rapid man-made warming occurring today, has repeatedly played a key role in mass extinction events of large animals, the megafauna, in Earth’s past.
Compared to its celestial neighbours Venus and Mars, Earth is a pretty habitable place. So how did we get so lucky? A new study sheds light on the improbable evolutionary path that enabled Earth to sustain life.
For centuries it has been thought that culture is what distinguishes humans from other animals, but over the past decade this idea has been repeatedly called into question.
When Charles Darwin published his theory of evolution by natural selection in 1859, the world hadn’t even heard of plate tectonics. The notion that continents drifted on molten rock currents deep in the Earth’s mantle was unimaginable.
The arrival of intense cold similar to the one raged during the “Little Ice Age”, which froze the world during the XVII century and in the beginning of the XVIII century, is expected in the years 2030–2040.
