This book is just beautiful, it contains everything you wanted to know about gorilla group behavior, social patterns, ecology, male and female reproductive strategies and survival strategies (nothing on anatomy or physiology). Not jargony. There's a section in the front to get one started on the basics of selection, ethology, sociobiology to pave for the application of the framework when it comes to the specific chunks of content on the gorillas. That really helped. After reading this I might look back and think, Wow, I now understand and predict the basics of gorilla behavior, to the extent of research at the time this book went to print! Not bad at all.
