I'm curious. How do you figure the natives killed off all the tens of millions of megafauna given that extinction occurred when they had just arrived over the b

  I read the summary reports by experts, and that's their explanation (incidentally, I'm not sure about counts, but "tens of millions" sounds high for most megafauna species -- their small numbers is part of their survival problem). If I remember right, the last time I read this story was at the elephant exhibit at the San Diego Zoo, or perhaps the standing exhibit at the La Brea Tar Pits. I'm just an interested outsider, so that's good enough for me. IIRC, the whole Bering Straits story is itself more complex than I learned in grade school. It was open longer, and was wider and bigger than originally thought. I believe humans came across in several waves that are genetically or archeologically separable. I read a lot of stuff in Science, and remember about 20%, and 50% of those memories are part-wrong, so take this with a grain of salt. ;-)

  Brazil has a bunch of archeological sites much older than the last land bridge on the strait, of course several historians go histerical with the mention that prehistoric humans might have crossed the pacific by boat, so to them only the strait idea is valid and south american paleontologists are liars... Or they just say that humans arrived here by unknown means, anyway we have 40.000 year old settlement sites, 40.000 years is time enough to extinguish whatever you want even if your population is in the hundreds...
