Evidence varies when Neanderthals died out

Evidence varies when Neanderthals died out
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. Instead, the researchers believe any co-existence between Neanderthals and modern humans is likely to have been much more restricted, perhaps a few hundred years. It could even mean that in some areas Neanderthals had become extinct before anatomically modern humans moved out of Africa. 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.

Neanderthals speech similar to humans - per DNA evidence Neanderthals might have spoken just like humans do now, new genetic findings suggest. Neanderthals are humanity's closest extinct relatives. Since their discovery more than 150 years ago, researchers have found out they could make tools just like our ancestors could, but whether Neanderthals also had advanced language, rather than mere grunts and groans, has remained hotly debated. To learn more, scientists investigated DNA from Neanderthal bones collected from a cave in northern Spain, concentrating on a gene, FOXP2, which is to date the only one known to play a role in speech and language. People with an abnormal copy of this gene have speech and language problems.

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. Oldest Cave Paintings May Be Creations of Neandertals, Not Modern Humans Hand stencils in El Castillo cave are older than previously thought. Image: courtesy of Pedro Saura In a cave in northwestern Spain called El Castillo, ancient artists decorated a stretch of limestone wall with dozens of depictions of human hands. They seem to have made the images by pressing a hand to the wall and then blowing red pigment on it, creating a sort of stencil.

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. Neanderthals not as portrayed in fiction-per science Archaeologists at the University of York are challenging the traditional view that Neanderthal childhood was difficult, short and dangerous. A research team from PALAEO (Centre for Human Palaeoecology and Evolutionary Origins) and the Department of Archaeology at York offer a new and distinctive perspective which suggests that Neanderthal children experienced strong emotional attachments with their immediate social group, used play to develop skills and played a significant role in their society. The research team, which also included Gail Hitchens, Andy Needham and Holly Rutherford, say there is evidence that Neanderthals cared for their sick and injured children for months and often years. Dr Spikins, who has a new book on why altruism was central to human evolutionary origins, How Compassion Made Us Human, (Pen and Sword) published later this year, said: "The traditional view sees Neanderthal childhood as unusually harsh, difficult and dangerous.

Did Volcanoes Wipe Out Neanderthals? Neanderthals may have gone out with a bang. At least three volcanic eruptions 40,000 years ago devastated Neanderthals' homelands. Geographic good luck may have allowed Homo sapiens to move into Neandertals' former haunts. Rethinking Neanderthals Bruno Maureille unlocks the gate in a chain-link fence, and we walk into the fossil bed past a pile of limestone rubble, the detritus of an earlier dig. We’re 280 miles southwest of Paris, in rolling farm country dotted with long-haired cattle and etched by meandering streams. Maureille, an anthropologist at the University of Bordeaux, oversees the excavation of this storied site called Les Pradelles, where for three decades researchers have been uncovering, fleck by fleck, the remains of humanity’s most notorious relatives, the Neanderthals.

How Should The Business Website Look Like? Website is an area where you can hoard ideas and information personally, but when that particular site is planned to host it must be designed in professional approach. One best website must hold clear contents, well defined products and services and how supportive you are to customers. Before naming and hosting your website, make sure that the website tells about you and your service in effective way. May be every individual in this world will have different ideas on their sites and some may not. New evidence on Neanderthal mixing New research on a 45,000-year-old Siberian thighbone has narrowed the window of time when humans and Neanderthals interbred to between 50,000 and 60,000 years ago, and has shown that modern humans reached northern Eurasia substantially earlier than some scientists thought. Qiaomei Fu, a postdoctoral fellow at Harvard Medical School (HMS) and first author of a paper describing the research, said the sample had a long history before making its way into her hands. The bone was found eroding out of a Siberian riverbank, but no one knows precisely where. The bone changed hands several times before finding its way to the Max Planck Institute for Evolutionary Anthropology in Germany, where Fu was working with professors Janet Kelso and Svante Pääbo.

‘Army Of Half-Cloned Mice' Created In China From Artificial Sperm Researchers at the Shanghai Institute for Biological Sciences have successfully created artificial mouse sperm that are easily replicable and, when implanted in an egg, more reliably grow into healthy mice. The resulting 125 pups, 39 of which weren't born healthy, could make up a small army of mice to be used for research into genetic diseases. In 2012, the same researchers created artificial sperm for the first time, which they were able to implant in a natural egg. It only sort-of worked—just two percent of the embryos developed into healthy mice. Researchers make artificial sperm by knocking out the nucleus of an egg and replacing it with one set of DNA from the father of the offspring-to-be.
