Resumen de Neanderthal sex, the aftermath
By studying Neanderthal genes in people alive today, researchers are beginning to appreciate how that interbreeding influenced their species. In one new study of 1,000 human genomes, Sriram Sankararaman and David Reich of Harvard Medical School and colleagues found that Neanderthal DNA is most common in regions of the genome with the greatest genetic variability, making them a prime target for natural selection. Joshua Akey and Ben Vernot of the University of Washington in Seattle have analyzed the Neanderthal DNA in a further 665 humans. Both their study and the Harvard one found a hotspot of Neanderthal ancestry in genes relating to keratin, a fibrous protein found in hair, skin and nails.
