I've read articles that do say however that the Australian Aborigines can be blamed for a lot of the killing off of that continents large marsupials after they migrated there 40 to 50 thousand years ago.

Here's an interesting theory along the same lines. A Duke University professor argues that dogs/wolves domesticated humans rather than the other way around. Otherwise the humans would have killed off the wolves just like every other predator that competed with humans for food.
