From SciTechDaily:
Scientists studying chimpanzees in the Budongo Forest of Uganda have found that these primates not only treat their own injuries but also care for the wounds of others. This behavior may offer insight into how early humans began treating injuries and using medicinal practices. While similar actions have been observed in other chimpanzee communities, the consistent occurrence of this behavior in Budongo suggests that medical care among chimpanzees may be more common and not limited to helping close relatives.
