This book was really interesting but unfortunately seemed to require you to remember a lot of technical names for parts of the brain, and other information that just didn't stick in my head. Some of the research done was really interesting though. I expected more on mirror neurons, but he mostly talked about other parts of the brain. I think some of them were two different names for the same region but I was never quite clear on what part of the brain was being talked about. Still it is interesting to think about being social being the most important thing about us and possibly a reason for the large brains to begin with.
