Pédagogie anglais English Club Open Culture - Free Cultural & Educational Media Online European Neanderthals were on the verge of extinction even before the arrival of modern humans New findings from an international team of researchers show that most Neanderthals in Europe died off around 50,000 years ago. The previously held view of a Europe populated by a stable Neanderthal population for hundreds of thousands of years up until modern humans arrived must therefore be revised. This new perspective on the Neanderthals comes from a study of ancient DNA published February 25 in Molecular Biology and Evolution. The results indicate that most Neanderthals in Europe died off as early as 50,000 years ago. The study is the result of an international project led by Swedish and Spanish researchers in Uppsala, Stockholm and Madrid. “The fact that Neanderthals in Europe were nearly extinct, but then recovered, and that all this took place long before they came into contact with modern humans came as a complete surprise to us.
Neanderthals died out earlier than previously thought, new evidence suggests Direct dating of a fossil of a Neanderthal infant suggests that Neanderthals probably died out earlier than previously thought. Researchers have dated a Neanderthal fossil discovered in a significant cave site in Russia in the northern Caucasus, and found it to be 10,000 years older than previous research had suggested. This new evidence throws into doubt the theory that Neanderthals and modern humans interacted for thousands of years. The research, directed by the University of Oxford and University College Cork in collaboration with the Laboratory of Prehistory at St Petersburg, Russia, and funded by Science Foundation Ireland was recently published in PNAS Online Early Edition. This finding challenges previous claims that late Neanderthals survived until 30,000 years ago in the northern Caucasus, meaning that late Neanderthals and modern humans were not likely to experience any significant period of co-existence.
Bunnies implicated in the demise of Neanderthals - 27 February 2013 BLAME it on the bunnies. The debate over what Neanderthals ate, and how it may have led to their demise, has turned to rabbits. Which, it is now claimed, they did not feast on. Signs that our extinct cousins hunted dolphins and seals were presented in 2008 as evidence of their sophistication. But, experts claimed in 2009, they weren't clever enough to catch fish or birds – which could have given our ancestors an edge. Then came the discovery of fish scales and feathers on Neanderthal tools. Now, John Fa of the Durrell Wildlife Conservation Trust in Trinity, Jersey, says the remains in caves around Europe became dominated by rabbits rather than large game around the time Neanderthals went extinct (Journal of Human Evolution, doi.org/kkn). It's not clear why they would have had more trouble changing prey, says Fa.
Neanderthals were ancient mariners - life - 29 February 2012 IT LOOKS like Neanderthals may have beaten modern humans to the seas. Growing evidence suggests our extinct cousins criss-crossed the Mediterranean in boats from 100,000 years ago - though not everyone is convinced they weren't just good swimmers. Neanderthals lived around the Mediterranean from 300,000 years ago. Their distinctive "Mousterian" stone tools are found on the Greek mainland and, intriguingly, have also been found on the Greek islands of Lefkada, Kefalonia and Zakynthos. That could be explained in two ways: either the islands weren't islands at the time, or our distant cousins crossed the water somehow. Now, George Ferentinos of the University of Patras in Greece says we can rule out the former. Ferentinos compiled data that showed sea levels were 120 metres lower 100,000 years ago, because water was locked up in Earth's larger ice caps. Ferentinos thinks Neanderthals had a seafaring culture for tens of thousands of years. New Scientist Not just a website! More from the web
First Love Child of Human, Neanderthal Found The skeletal remains of an individual living in northern Italy 40,000-30,000 years ago are believed to be that of a human/Neanderthal hybrid, according to a paper in PLoS ONE. If further analysis proves the theory correct, the remains belonged to the first known such hybrid, providing direct evidence that humans and Neanderthals interbred. Prior genetic research determined the DNA of people with European and Asian ancestry is 1 to 4 percent Neanderthal. The present study focuses on the individual’s jaw, which was unearthed at a rock-shelter called Riparo di Mezzena in the Monti Lessini region of Italy. PHOTOS: Faces of Our Ancestors “From the morphology of the lower jaw, the face of the Mezzena individual would have looked somehow intermediate between classic Neanderthals, who had a rather receding lower jaw (no chin), and the modern humans, who present a projecting lower jaw with a strongly developed chin,” co-author Silvana Condemi, an anthropologist, told Discovery News.
Who Didn't Have Sex with Neanderthals? Very few populations of modern humans do NOT carry genetic traces of Neanderthals, say researchers. The only modern humans whose ancestors did not interbreed with Neanderthals are apparently sub-Saharan Africans, researchers say. New findings suggest modern North Africans carry genetic traces from Neanderthals, modern humanity's closest known extinct relatives. Although modern humans are the only surviving members of the human lineage, others once roamed the Earth, including the Neanderthals. Genetic analysis of these extinct lineages' fossils has revealed they once interbred with our ancestors, with recent estimates suggesting that Neanderthal DNA made up 1 percent to 4 percent of modern Eurasian genomes. Although this sex apparently only rarely produced offspring, this mixing was enough to endow some people with the robust immune systems they enjoy today.

Gene breakthrough shows Neanderthals in new light - opinion - 18 July 2013 WHEN Neanderthal bones were discovered in the 19th century, their robust build and heavy brows led palaeontologists to characterise them as brutish, and their name is still pejorative today. Since then, we have found ample circumstantial evidence to suggest this stereotype is far from fair. Tools, jewellery and even cosmetics discovered among Neanderthal bones suggest that they were uncannily like us – a view strengthened when their genome was sequenced, showing a remarkable genetic overlap. Now the Neanderthal epigenome – the system of on/off switches that modify gene activity – has been deciphered (see "First look into workings of the Neanderthal brain"), allowing us to directly assess the mental life of our extinct cousins for the first time. This work is just beginning. This article appeared in print under the headline "Extinct cousins out of rehab" New Scientist Not just a website!

No known hominin is common ancestor of Neanderthals and modern humans, study suggests -- ScienceDaily The search for a common ancestor linking modern humans with the Neanderthals who lived in Europe thousands of years ago has been a compelling subject for research. But a new study suggests the quest isn't nearly complete. The researchers, using quantitative methods focused on the shape of dental fossils, find that none of the usual suspects fits the expected profile of an ancestor of Neanderthals and modern humans. They also present evidence that the lines that led to Neanderthals and modern humans diverged nearly 1 million years ago, much earlier than studies based on molecular evidence have suggested. The study, which will be published online this week by the Proceedings of the National Academy of Sciences, was carried out by an international team of scholars from The George Washington University, Konrad Lorenz Institute for Evolution and Cognition Research in Austria, Indiana University and Atapuerca Research Team in Spain. P. What comes next?
Much Earlier Split for Neanderthals, Humans? In the ranks of prehistoric humans, Neanderthals were our closest relatives. We were so close, in fact, that our species interbred with theirs. Tracing back our lineages, there must have been a last common ancestor of Homo sapiens and Neanderthals sometime in prehistory. But who was this mystery human? Picking out direct ancestors in the fossil record is tricky. In the last five years, anthropologists have used DNA to reconstruct the evolutionary history of humans. The dates range from more than 800,000 years ago to less than 300,000, with many estimates in the neighborhood of 400,000 years ago. But this may not be so. What's new? In a study published on Monday in the Proceedings of the National Academy of Sciences, George Washington University anthropologist Aida Gómez-Robles and colleagues turned to teeth to test what had been gleaned from genetics. With that hypothetical shape in mind, Gómez-Robles and coauthors compared what was expected against fossils found so far. What does it mean?
