Wait, wait. They only happened at that boundary in North America. In 
Australia it was way earlier, for example.

Not necessarily, because the African animals were already used to the 
presence of humans and had indeed coevolved with their presence. No drastic 
change in hunting technology is known from Africa around a relevant time, 
AFAIK.

Then it should have happened at the end of the first ice age, not two 
million years later.
