Small clarification: an ape when it sees us probably still thinks of us as a different kind of ape.

Studies have shown that chimpanzees can identify both chimpanzee and human adult/children/babies faces at a similar proficiency but do not recognize monkey faces as well. Interestingly, they also have similar difficulty recognizing faces when displayed upside as humans do. Is this proficiency due to close interactions with human handlers or a shared cognitive ancestor?
