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."
Heck yeah! TODAY 80% of the human population lives within 100 miles of the coast.
During the last Ice Age sea level was 200 feet lower.
Do the math, guys...
