A popular science book about current thinking on the history of primates. Overall, good stuff. Interesting, with a lot of stuff I hadn't known in there.
The author's own professional opinions come on pretty strong when he discusses disputes, but I found it hard to take this too seriously. Most of the disputes appear to only exist due to the paucity of fossils, so I assume most of this will become obvious as more are discovered.
The book also goes into more detail than I was interested in about certain key remains. I ended up skimming pages of analysis of teeth, for instance. Not a big deal, really.
