The Seven Daughters of Eve: Bryan Sykes

This was a fascinating book that luckily spends the first portion teaching about DNA ( or I would have been completely lost) I love the journey to discovery and how there are so many people working on the same idea that come to the same conclusions even though there are many areas of thought. There are actually 33 clans, though he speaks about 7. Very interesting read if you are into genealogy and science.
