Query: No original thought here

While Genes, Peoples and Languages is written in appealing,informal narrative, the engaging chatter fails to disguise that there isn't much original thought here. The information he's dealing with is exciting and ought to provoke speculation and new directions of thought, but the author contents himself with forcing the findings into the same old nineteenth century doctrine we've been laboring with all along. He tells us about the astounding genetic similarities between all peoples,but barely wonders how current thinking, which he reviews, on human evolution and global expansion can be reconciled with the new genetics. I've been hoping for someone to ask, given these findings, Who really are we? What was our past? Genes, Peoples and Languages isn't that book.
