A review of the work of paleogenetics led by Svante Paabo from the German Institute for Evolutionary Anthropology of the Max Planck Society in Leipzig, in which researchers report the third highest Neanderthal genome sequenced with high coverage. The object of the study was a representative of Neanderthals from the Chagyrskaya cave in the southern part of the Altai Territory, who lived there about 60-80 thousand years ago.
According to the results of the new work, the representative of the Chagyrskaya cave turned out to be genetically closer to the European Neanderthals than to the older Neanderthals from the Denisova Cave, located 106 km east of the Chagyrskaya. In addition, in the Denisova cave, the remains of a girl were found, whose father was a Denisovian, and her mother was a Neanderthal, just relatively closely associated with the later Neanderthal from the Croatian cave of Vindia. So these ancient populations were found in the Altai Territory. A connection with Vindy indicates the replacement of Neanderthal populations.
