Neanderthals different in north, south
El Sidron, Spain (UPI) Dec 21, 2006 Remains of 43,000-year-old Neanderthals found in southern Europe had broader faces than their northern counterparts, Spanish and British researchers say. Researchers analyzed the mandibles of Neanderthals discovered in Spain near El Sidron, revealing the variations. The southern European Neanderthals had broader faces with "increased lower facial heights," said Markus Bastir, with the functional morphology and evolution research unit of Hull York Medical School in Britain. "This revealed an astonishing North-South morphological gradient and gives us an idea of typically Southern European Neanderthal facial shape," Bastir said. The findings were published in the Proceedings of the National Academy of Sciences. Community Email This Article Comment On This Article Related Links All About Human Beings and How We Got To Be Here
Protein That Kills Cells May Help Memory
Champaign, Ill. (UPI) Dec 20, 2006 U.S. scientists say they've determined a protein known to kill cells also plays an important role in memory formation. University of Illinois-Champaign researchers say their work exploring how zebra finches learn songs might have implications for treatment of neurodegenerative conditions such as dementia and Alzheimer's disease. |
