A PooterGeeker wrote to ask how she could take part in the Genographic Project. The answer is here, though some of us “in the business” might get a little bit sniffy at the idea of a human sample group that is not only partly self-selecting, but includes people who’ve paid to be experimental subjects. Of course, in return for your money you are promised anonymized information about your genetic origins. The editor of a related scientific journal asked me, “How many thousands of certificates do you think they already have printed up saying, ‘Your ancestors came from Africa’?”
