How do non-human apes cool their body temperature in warm climates?
First they have less cooling needs than us, shady forests are cooler than sunlit savannah, they also are not as active, especially the larger ones, at least not in the hottest parts of the day. keep in mind chimps are much smaller than us so they have an easier time cooling off. They cool themselves the same way we do, by sweating, its just not s effective as it is in us, but then it doesn't need to be. .
