Ah, yes.
You are aware that homo sapiens sapiens is according to real science 200,000 years old? The Genographic Project suffers from many cargo cult science problems, especially they have a strong believe in the accuracy of DNA markers, without really understanding them (With markers alone, I can't prove with certainty, who is your grand-grandfather - and often only with some uncertainty, who is your parent). Also I can't find anything on their website that they use mitochondrial DNA as input, which is just strange as this special DNA gives a much stronger indication of ancestry over many generations.
