Query: really interesting

I really got a lot out of this book--it's a bit of a dry read at times, and some of the genetic science gets a little bit heavy (particularly in the beginning), but I learned a lot from reading. A lot of quotable new ideas in here that I wanted to talk about with friends immediately--the extinction of Neanderthals, the early advent of modern humans in Australia, the difference between human and animal as appreciated by a simple grammatical structure, and the ability to track lineage from placental and Y chromosom DNA being some things that spring immediately to mind. Worth dipping into.
