Single African origin of human Y Chromosome and mtDNA
A new paper that compares Y Chromosome and mtDNA apparently shows a single African origin for humans between 50,000 to 70,000 years ago. This is nothing particularly new or exciting, however I’m still trying to scrape together some real information (P.N.A.S. is, as always, hiding its latest papers from anyone without a shiny journalist badge).
However, National Geographic coverage has a few interesting tidbits, despite writing it up as “another nail in the multi-regional hypothesis” (really now – does anyone still believe that humans had more than one origin?).
More when I can find it. More here
