Spencer Wells' "Journey of Man: A Genetic Odyssey"

[tom]

Hi all,

According to this guy, through tracing genes of people across the world,
he concluded that all human come from Africa. I am wondering has anyone here
read his book ? How does his theory fit into the Thao's story about human
history in TP book ?

For information about him:
