Not "last" because all the others are about to die out, but because they are the most recent of the apes to be studied thoroughly. Kano (zoology, Primate Research Institute, Kzota, Japan) recounts his observations and experiences in the Wamba Forest, Zaire, 1974-85, studying what many believe to be the species most closely related to humans. He particularly notes how the lifelong sexual and quasi-sexual behavior among individuals of any age and gender, alleviates the competition and dominance prevalent among other primates.

A very interesting look at the Bonobo (pygmy chimpanzee). This is not a book full of prose or typical storytelling, but a collection of observational accounts and data. That should not imply that the book is boring, for if you are one who is truly interested in understanding more about these fascinating primates you will find this book quite informative and enjoyable.
That said, I will not pretend that the presentation isn't a bit dry, but I do not think that is a negative for this type of book as its dryness can serve as a testament to the validity of the observations, etc while avoiding any overt bias.
This book gets 4 stars for content more than its delivery. In addition, I also liked the hypotheses offered on homo sapiens pairing as well as their genesis of aggression which were given in the last chapter.
