Did the immigration of bison from Eurasia cause large mammal extinctions in the late Pleistocene? An interesting line of inquiry, though I'd definitely want to see a good account of the effects of another immigrant from Eurasia, one with two legs, taken into account.
Hat tip: Skolai Images.
Update: Or did it have something to do with a comet shower?

I have the same reservations you do re bison, and the comet theory-- not that new-- has been pretty well discredited. I have print if not cyber sources if you mail.
