Animals unexposed to humans, the most dominant apex predator in history, do not fear them. Their behavior, as we have seen in historic evidence, doesn't have time to adapt to the new threat before they are wiped out.
I did not say that a few spear points in a few mammoth carcasses was conclusive evidence of their mass eradication at the hands of human hunters.
I said that the mass disappearance of mega-fauna that seems to coincide with the introduction of human populations in Australia, New Guinea, Madagascar, and America (and elsewhere) seems to indicate that human arrival accompanies mass extinction of mega-fauna.
It might all just be coincidence.
In case....after case.... land mass..... after land mass.
Yep, it might just be a coincidence.
With the exception of Asia and Africa.
