Although sweating is found in a wide variety of mammals,[6][7] relatively few (apart from humans, horses, some primates and some bovidae) produce sweat in order to cool down.
Persistence hunting, also known as endurance hunting or long-distance hunting, is a variant of pursuit predation in which a predator will bring down a prey item via indirect means, such as exhaustion, heat illness or injury.[1][2] Hunters of this type will typically display adaptions for distance running, such as longer legs,[3] temperature regulation,[4] and specialized cardiovascular systems.[5]
Humans are some of the best long distance runners in the animal kingdom;[6] some hunter gatherer tribes practice this form of hunting into the modern era.
That’s being done by humans for amusement. It’d kill most animals. Not saying that it’s comfortable, but we can deal pretty well with an awful lot of heat if we have to.
If you want to talk the talk, you gotta walk the walk. But if you can do the walk, hey…might as well strut it.
