Jane Goodall has some interesting oberservations regarding infanticide among chimpanzees in her book "Through a Window." While chimpanzees will attack females that are strangers to a group violently, their infants will only, and in rare instances, die as casualties, but not be directly attacked. Infanticide within a community has only been observed in a few cases and all perpetrated by the same female individual and her daughter. However, she concluded from their behavior that their reason lay solely in the meat of the hunted infants.
