Question

What caused the extinction of saber tooth tigers, woolly mammoths, camels and horses in N. America?

Answer 1

Climate change!  The Ice Age ended.

And there wasn't an SUV in the entire world.

Answer 2

Theories  I have heard on the subject are climate change (due to the end of the Ice Age), over hunting by humans and one interesting one about a meteor hit in northeastern north America.   This last one is mostly supported by finding evidence of superheated metal fragments embedded in the tusks of a large portion of the mammoth tusks in North America from one period of time.  Personally I believe that all three put stresses on the population of these creatures eventually leading to their demise.

Answer 3

it is the ice age when mostly of them died but the ones who were left were hunted unendlessly by the indians of N. america

Answer 4

ummm I thought that was obvious hellooo it was obiously chuck norris

Answer 5

Ice melted

Over-hunted

Replaced by other, better adapted, species

Most Camels crossed the ice bridge and the ones that were left died out.

Answer 6

It was a combination of things, viruses, hunting, and the ice age. All were contributing factors

Answer 7

The ic emelted, and they could not surive.

Answer 8

No one's really sure.  It isn't clear that they all became extinct at the same time, either.  But climate change and overhunting from humans are the most common ideas; at present, there really isn't enough information to distinguish between them.

Answer 9

ice age and over hunting were the key factors food ran out for predators and they died
