This is all speculation. The only "evidence" that the "so-called" experts had was that it appeared that the Giant Sloths died out around 11,000BC, and that it is a common assumption that humans emigrated to North America via the land bridge around 11,000 BC. That is not proof.

Proof are Giant Sloth bones with cut marks on them. Proof consists of cave paintings of Giant Sloths being hunted. Proof consists of a number of other things that are evidence for this speculation.

For all we know, the sloth tasted terrible. So just because one theory dovetails into another theory is no reason for an out and out connection, that is unless one states that the speculation has some solid rationale behind it.

I think the main hole in their theory is that there is irrefutable proof that the Clovis First Theory is dead.

Unless they can come up with something better than a Clovis point as an indication of a new factor around 11,000 years ago, this theory holds no water - not even ice.

Why did man live here for over 30,000 years without eating into extinction all the ice age megafauna, and then all of a sudden, 11,000 years ago wipe them out??

Some cultural change?? New "invaders"?
