Furthermore, increasingly sophisticated DNA studies of extinct populations have shown that, despite their general classification as the distinct species Homo neanderthalensis, Neanderthals interbred with modern human groups as they dispersed out of Africa. As a result, many people’s genomes contain roughly 1% Neanderthal DNA.
此外，越来越复杂的灭绝人种DNA研究表明，尽管“尼安德特人”是一个不同的物种，但他们也与走出非洲的现代人杂交。结果，许多人基因组中包含大约1%的尼安德特DNA。
