Sunlight adaptation region of Neanderthal genome found in up to 65 percent of modern East Asian population

With the Neanderthal genome now published, for the first time, scientists have a rich new resource of comparative evolution. For example, recently, scientists have shown that humans and Neanderthals once interbreed, with the accumulation of elements of Neanderthal DNA found in up to 5 percent in modern humans. Scientist have found evidence of accumulation of a Neanderthal DNA region found on chromosome 3 that contains 18 genes, with several related to UV-light adaptation, including the Hyal2 gene. Their results reveal this region was positively selected and enriched in East Asians, ranging from up to 49 percent in Japanese to 66 …read more
