Here's Frans de Waal's first chapter (1997) about Bonobo chimpanzees -
(University of California Press, in the N.Y. Times) -
which I've added to the fairly new, Bonobo Chimpanzees' wiki, subject page at WUaS -
(see, too, the WUaS Primatology wiki page -
with an invitation to study, learn, teach (to your web cam, etc.), add resources, and create at WUaS,
as wiki, in these and all subjects
added more resources to the WUaS Bonobo chimpanzee wiki subject, - this time some resources from PBS's Nova ... http://www.pbs.org/wgbh/nova/nature/bonobo-all-us.html ...
