At the risk of being called a troll I'll reply to myself. How's this:

And this:

Seems it wasn't ice or cold that killed mammoths in Asia. In fact the ones in warmer regions died out first!

There are many means by which we might have contributed to extinction without the use of sophisticated machinery.

1. We could have brought in diseases
2. We could have started fires destroying habitat
3. We could have killed to top predators leading to an imbalance with food supplies
4. We may have just been the final insult to a precarious balance

And of course it could just be a coincidence.

Unfortunately we come with a long history of causing extinctions. So coincidence should be rather low on the list.

Science teaches us that the answer most likely to be correct is one that will not flatter two-legged semi-sentient primates.

DA. I believe the influence of number two in your list has been very much under-estimated in considering the influence ancient humans had on the environment. It was certainly important in NZ and the vegetation of Australia is often refered to as an Aboriginal artifact. A link I provided on the previous page says as much. I also found one that suggests there is a connection in Northeast USA between an increase in fire and dissappearance of mastodonts:

Anyway, we can't get away from the fact that there is a high correlation between the first appearance of humans and the dissappearance of many other species.

Now. Back to how did humans get through the ice that covered Northern Canada at the time?
