Thousands of amateur genealogists have contributed to a huge database of family relationships, including genetic analyses. What does this teach us about human populations and evolution?
It touches on some issues covered in more detail in Steve Olson's book, Mapping Human History: Genes, Race, and Our Common Origins, which remains surprisingly relevant today despite the explosion in genetic data. That's because Olson did a good job on the population genetics side.
Oh, and yes I am a descendant of Charlemagne. Woo-hoo!
