Human evolution
Studies of the human genome, especially the Y-chromosome DNA and mitochondrial DNA, support a relatively recent African origin. Evidence from DNA also supports the recent African origin. The details of this great saga are not fully established yet, but by about 90,000 years ago modern humans had moved into Eurasia and the Middle East. This was the area where Neanderthals, Homo neanderthalensis, had been living for a long time (at least 500,000 years in western Europe).
