@amphiox — we should have qualified that statement more, I’ll go back and change it to “researchers suspect that Australopithecus…” The theories on when our hominid ancestors lost their thick hair are somewhat speculative, but most link the change to the rise of bipedalism on the sun-baked savannah, when heat dispersal suddenly became very important to big-brained hominids.

Australopithecus also had less hair

Wait a minute. When did we find this out? (And how?)
