YES!! Again, if you haven't already, go online to Amazon and get yourself a cheapie used copy of "Scars of Evolution" by Elaine Morgan. Absolutely fascinating. Helps explain possibly WHY human babies know instinctively to hold their breath when placed in water, why they're born with a large amount of white fat (it floats!) as opposed to chimp and ape babies, which are born with a thin layer of brown fat, which has no flotation qualities. So it is that after Christmas when I have put on a bunch of fat from eating too much fudge and chocolate-covered cherries, I rationalize it and figure it's just that much more flotation for me when I go swimming. And swim I do -- as a means of burning off said fat to keep my girlish figure! *sigh* So many contradictions, so little time!
To all: I have to own up to having read "The Naked Ape" in college about thirty years ago and have never since been able to take the anthropologists sifting through chimpanzee bones in the Olduvai Gorge seriously. I don't claim any ownership of the "aquatic origin" but it's the only one I've ever heard that actually made any sense. I sometimes yell at anthropolgy programs on Discovery and the Science Channel: "Hey, s***head, you're looking in the wrong place! Figure out where the beaches were 2 million years ago and call me back."
