About the same time Grizzly bears were able to migrate to the lower 48 States...

Grizzly bears are an exotic species which originated in Europe and Asia.

12.8 thousand years isn't even a pimple on a bull's ass in geological terms.

> If a comet or asteroid were responsible for the cooling, it would suggest that Earth’s climate can be influenced by events far beyond our planet

Like oh ... THE SUN !!!

Stuff like this makes me think Climate Scientists are dumber than Racial Gender Studies grads ..

...minorities & trans children hardest hit.

Horses first appeared in North America so they are an exotic species in Eurasia and Africa. I don’t know when they managed to get from North America to Asia.

[catnipman]

time for Democrats to demand that large meteorites be outlawed because climate change ...

[piasa]

Camels,too.

Are they sure it wasn’t the stone age cars man was driving? I’ve watched the Flintstones. Come on, man. It was Fred, wasn’t it?

Ancient ancestors of horses first appeared in North America.

There were no modern horses in North America until Europeans introduced them.

On the positive side, if at some point in the future our climate is running too warm, we can always grab a smallish asteroid and drop it in an ocean. Voila, instant cooling.

Climate change solved.

Does this mean We’re not all gonna die in 4.4 years?

[Red Badger]

It means that this story will be spiked by the MSM hard and fast!................

[Verginius Rufus]

The American Museum of Natural History piece about the evolution of horses doesn't mention Eohippus. I thought that true horses first appeared in North America since none of the ancestral species appear to have been found anywhere else. Probably the Paleo-Indians over-hunted the horses in North America causing them to become extinct in the New World until after 1492.

Or maybe horses were just too lazy to make their way back here after they got off the ark.

[Does so]

...and Polar Bears evolved from Grizzlys...

[Does so]

This was also about the time that the gene for blue eyes appeared in humans.
