Are there better natural responses to heat that we see in mammals?
I know sweating isn't perfect, for the reasons you mentioned, but do we see nature evolving any better solutions at a mammalian level?
My armchair understanding is sweating is a natural marvel with nothing else like it seen in creatures as large as us. That it truly is a differentiator between humans and other animals (or mammals at least). Sweating is the foundation of humans ability to engage in long-distance endurance running which is one of our unique features, also called persistence hunting[0]. You can easily draw a line between this sweating and our ability to travel large distances and hunt the way we did, which in turn can be connected to humanity's success as a species on earth.

- dalbasal 4y agoAll true, and impressive considering that we recently evolved from tree dwelling primates but... There are plenty of animals adapted to heat, and can perform similar feats. African wild dogs, dingos and other canines can persistent hunt in similar hot conditions. They're much faster than us, so it's not as extreme a strategy as human "track and spook" methods... but arguably better. Elephants manage to carry those huge, heat retaining bodies. Our Savannah nurseries are full of megafauna like us that live in these conditions effectively.
