Evaporation is an extremely good way to get rid of waste heat, but prey
animals can only do it through the mouth by panting. However humans are
naked apes and can sweat and evaporate water over their entire body, as a
result they are much better at getting rid of heat when they exert
themselves than any other animal of similar size. So humans became marathon
runners not sprinters, they are not very fast but they are persistent and
can keep running after their speedier prey have collapsed from heat
exhaustion.
