There is a saying, “Animals sweat, men perspire and women glow”. Well people, let me tell you…I sweat. And I sweat a lot!! Depending on the circumstances, rivulets of water run…not just trickle, but run down my face and neck. I’ve actually witnessed my own fore arms bead up and dew on a summer’s night (granted I was packing UPS trucks in a scorching hot Texas warehouse, but still it’s not like all the other fore arms in the joint were doing it). So no, I do NOT glow, simply put, I sweat.

This is why my interest was piqued today as I read an article about Nina Jablonsky, an anthropologist studying the significance of human skin. She stated (emphasis mine):

It happened this way. There was a tremendous takeoff in human evolution about two million years ago when primates who could no longer be called apes appeared in the savannahs of East Africa. These early humans ran long distances in open areas. In order to survive in the equatorial sun, they needed to cool their brains. Early humans evolved an increased number of sweat glands for that purpose, which in turn permitted their brain size to expand. As soon as we developed larger brains, our planning capacity increased, and this allowed people to disperse out of Africa. There’s fossil evidence of humans appearing in Central Asia around this time.

Maybe I am a biological catalyst for the evolution of greater human intelligence.
