I don't doubt that human sweat. It seems a logical fallacy, and tell more about the theorist (those bloody hunter apologist) than the Hominid, to assume that sweat ability (and feet, gait, hairlessness, etc) came from persistence hunting (it could be anything, or a lot of various adaptation) Where sweat came from? From Dancing Do you want to start the Persistent dancer theory with me ? I need some well researched facts to write "Born to dance" To woo their mate, homo Erectus (like a lot of animal) had to dance for hours. Sweating help to court the mate longer, so is having arched foot, and gait, and a nice toupee. And so, only the most persistent dancer could procreate Do I have proof? Lot of tribe nowadays still dance for hours to woo potential mate. And it's not only in Africa
