[QUOTE]Originally posted by Clyde Winters: [QB] [QUOTE]Originally posted by DD'eDeN: [qb] Tony Capra of Vanderbilt University in Nashville hypothesized last week at the annual meeting of The American Society of Human Genetics that genes we have considered to variant of Neanderthals and inherited to modern humans outside of Africa are not particularly Neanderthal genes, but rather, represent ancestral humans. [DD: African genes, or perhaps pan-tropical-rainforest-belt-genes] In other words, we can thank Neanderthals for giving back thousands of ancient African gene variants that were lost to Eurasians as their ancestors swept out of Africa in small bands, perhaps 60,000 to 80,000 years ago. He and his team came about this finding by identifying African variants as they scoured the genomes of more than 20,000 people in the 1000 Genomes Project and Vanderbilt's BioVU data bank of electronic health records. Curiously they found vast stretches of chromosomes inherited from Neanderthals also carried ancient alleles, or mutations, found in all the Africans such as the Yoruba, Esan, and Mende peoples. In fact, there's about 47,261 of these SNPs across the genomes of Europeans and 56,497 SNPs in Asians. In Eurasians people, these alleles are only found next to Neanderthal genes, suggesting all this DNA was acquired at the same time, when the ancestors of today's Eurasians mated with Neanderthals roughly 50,000 years ago. h/t Kambiz Kamrani @ Anthropology.net [/qb][/QUOTE]These researchers have misinterpreted the data. If Neanderthals acquired the genes 50kya they were carried there by Africans, not Eurasians as assumed by the authors of this study. The most interesting thing about their findings is that the Mande expanded all the way up to China, and the Yoruba lived in Anatolian for an extended period of time before they migrated back into Africa.
