Genes, Peoples, and Languages

It's probably unfair to give the book only three stars because the problem really is that I'm not equipped with the understanding of genetics to really follow what I was reading. I am very interested in the migration of people from our mutual place of origin but I'm more interested in the evolution of languages, which is the real reason I got this book. And the book's last two chapters, which deal with language and cultural evolution, I will probably re-read.
