Mammals' Lucky Space Impact

No, but your descendants would.

Then how do explain the starving idiots that live in a desert? They and their ancesters were too stupid to move their tent 10 feet every few hundred years?

Some would remain, but humans like animals radiate toward suitable environments, the places we lived 1,000 years ago may not be as suitable as they once were.

The deserts of SE California were covered with lakes and had a temperate climate 4,000 - 5,000 years ago. This changed and the most natives moved on, those remaining had to adopt different strategies.

OBTW: I don't think that this migration is a cognitive decision.

George W Bush was elected in 2000 A.D. A little bit later in 10,000,000 A.D., a Democrat finally won the Presidency...

Ooh, I like your optimism!

Too bad this article didn't include a phylogenetic tree. It would really help to visualize the relationships between the mammals.

Much prior to that the Sahara desert was a populated grass land.

I think we need to give early man more credit. (Maybe if they were as stupid and lazy as some of us are now, we wouldn't exist.) I believe that early man migrated far more than what we think. In a mobile society, of coarse you would move if conditions became adverse. (And heck, no government to demand they fix it.)

1,000 years = about 50 generations is plenty of time for groups to make a move to "greener pastures" as would be the want of hunter/gatherer societies.

Mankind, bless 'em, has always wondered what lay over that next mountian. The frightened, weak, slow hairless ape forced to use his wits to survive in a world ruled by tooth and claw managed to come out of Africa and walk the moon in something like 5,000 generations.

For awhile, birds were "top dog."

Blam, here's a link to the Paleomap Project. It has global maps of virtually every era of Earth's history.

Thanks.

I've heard that during this time there were no ice caps on the poles except in winter. Mammals could have migrated across the North America-Greenland--Europe land bridge as well as the Asia-North America land bridge.

Assuming the amount of water on earth was relatively constant, wouldn't the absence of ice caps mean more water for the oceans and thus fewer land bridges?

[PatrickHenry]

Great link.

If the enviromentalists are right...and extinction is growing fast nowadays...we are doing the planet a favor. Fortunately I don't accept their science anymore than these preposterous darwinite so-so science stories.

The impact could have triggered the greenhouse warming thought to have encouraged

Gee, you folk call this science? "could have" and "thought" in one sentence make this whole article just evo propaganda for the unintelligent masses.
