New tools identify key evolutionary advantages from ancient hominid interbreeding

(Molecular Biology and Evolution (Oxford University Press)) Neanderthals. Denisovans. Homo sapiens. Around 50,000 years ago, these hominids not only interbred, but in some cases, modern humans may have also received a special evolutionary advantage from doing so. In a new study published in the advanced online edition of Molecular Biology and Evolution, computational biologists Fernando Racimo, Davide Marnetto and Emilia Huerta-Sánchez have developed statistical tools and simulations to successfully identify the signatures of these interbred genomic regions.
