Humans have sweat and we all know how that provides cooling along with the remaining vellus hairs acting as wicks.

So how do hominids, our close relatives (some of which are more massive than humans) regular their body temperature, given that they are completely covered in fur like typical mammals?

I’m specifically interested in how a human who had an atavism that’s like generalized hypertrichosis terminalis would fare and get by.

in my story, it’s due to a repaired chromosome 17 that didn’t turn out the way that was intended.

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. .

Some of the tactics include: _ More frequent breaths. _ Sweat more. _ Loss of skin moisture.
