Sweating was a very important part of how the Homo Erectus hunted its prey. The Homo Erectus' skin had less hair than the skin of its ancestors, exposing its sweat glands. As a result, the Homo Erectus was able to hunt its prey by chasing its prey for hours on end, until its prey was either exhausted and/or overheated. The reason the Homo Erectus did not become over-heated is due to the fact that as it ran, its sweat would be constantly cooling the homo Erectus down, an advantage not given to its prey. Furthermore, the Homo Erectus' long legs and rugged joints are built for long distance running. As one can see, the Homo Erectus species likely may have gone extinct due to starvation much earlier than they actually did go extinct  had they not been able to sweat.

Return to History 8 Human Origins Concepts

Hominids began to loose hair allowing their bodies to sweat. They used sweating as a way to lower their body temperatures in the heat. Humans sweat more than any other animal even though our glands are roughly the same size. Sweating enables the body to cool down in another way instead of panting. Panting only cools the body after large bursts of energy. If a hominid goes on a long chase to hunt an animal panting would only lead to hyperventilation and could end fatally. Sweating is one of traits that makes us human.
