摘要:
Several Portuguese language sources from the 16th and 17th centuries document observations of chimpanzees in Sierra Leone, made by Eur-African traders, Jesuit priests, and their informants. They detail both naturalistic observations of chimpanzees and a unique record of historical perceptions and folklore of chimpanzee behavior and physical traits. In particular, a description of chimpanzees using stone hammers to crack open oil palm nuts is the earliest record of such behavior.
