I don’t believe any of that. You’re saying the paltry amount of humans then overcame the extensive population of Dire wolves, Short faced bears (a running bear 5 foot at the shoulder), American lions and saber tooth tigers. As a hunter I don’t think so. more likely a sudden deep freeze or heat wave killed them all off because it happened suddenly.
Not what I said at all. Try reading my post again.
Couple facts:
Dozens of large animal species disappeared in a very brief period, from a historical POV.
This occurred shortly after the most widely accepted date for humans arriving in the Americas.
I am not stating that B caused A, only that if there were no connection it would be a truly amazing coincidence.
There are lots of explanations proffered, but none that make a great deal of sense.
As for the “climate change” being to blame idea, the extinction did occur shortly after the end of the last glacial period. But many of these species had lived through a dozen or more glacial/interglacial cycles, but disappeared all at the same time after the most recent one.
Not limited to the Americas, BTW. The only parts of the world where megafauna survived in large numbers are those areas where humans and the megafauna are claimed to have evolved together, Africa and South Asia. Everywhere else the megafauna disappeared, and generally within a short time after humans arriving.
IOW, heck if I know.
