Resocialization of captive chimpanzees: An amelioration procedure
Group formation protocols are described. 59 of 60 chimpanzees were successfully resocialized to compatible group living. Severe wounding has not occurred in our facility, perhaps due to luck, but more likely due to the close daily behavioral monitoring of each...

Food sharing has been proposed as the propeller of hominid evolution, particularly of the development of systems of mutual social obligation. Yet, food sharing in our closest relative has never been subjected to a rigorous analysis of reciprocity. Provisioning of...
