Why don't we think nothing of nudity? Because of weather, because we aren't all haired up like dogs and cats, we are for some reason a rather hairless species, which is odd since hominids have lived in the northern regions for a long time, although we are all descended from the African branch that found brains less than 100,000 years ago, but wouldn't you think Cro-Magnon or the proto-Asians developing during the Wisconsian Ice Age (the last one - until the next whichc is imminent) would have been selected for hairiness? Why, I ask myself during this New England winter, can't we have some kind of hair covering? Maybe their was a sexual selection preference, which is a strong factor in evolutions, (girls don't like the hairy? Guys don't like the hairy girls.) like the male peacock tail, which serves no other survival purpose. I'm not completely up to date on the thinking on this , but read 'Descent of Woman' by Ellen Morgan years and years ago and she spelled out the Aquatic Ape theory, the idea that there was a phase in the evolution of homo sapiens, during some awful hot arid stage in Africa, the last interglacial I suppose, when our ancestors dwelt only on the coastline and spent a real lot of time in the water, and thus lost hair in order to aid swimming, like other rather unhairy mammals like whales, and quadropeds like rhinos. And pigs. Pigs are a real analog to humans, rather unhairy, sweaty, pretty smart for a beast. Some other interesting ideas in 'Descent of Woman' was that women have bigger butts because they spent so much time sitting on the beach with kids in their laps, and that underarm hair is there cuz swimming is not negatively effected by it.





OK next post
