Joan Silk

University of California at Los Angeles anthropology professor Joan Silk published a study of chimpanzees in the Oct. 27, 2005, Nature that showed that the chimps were motivated to obtain rewards for themselves but not to provide rewards for other group members. In other words, they did not show altruistic behavior, contrary to expectations raised by the fact that they participate in collective activities such as food sharing and hunting.
