Rosinate…

I hope you’re pulling my leg.

Intra-species warfare guarantees that un-natural selection still occurs, it just morphs into alternate pressures/selections.

The evolution of the horse occurred in North America, right along with the camel, both of which went extinct when super-volcano Yellowstone National Park blew.

Fortunately before that extinction they had spread to the old world. It would take the Spanish to bring the horse to the plains natives by way of rustled steeds.

As if we don’t have enough to worry about, Yellowstone is morphing so much that we may be a lot closer to a big blow than can be imagined.

The last big blow, Toba,

( http://en.wikipedia.org/wiki/Toba_catastrophe_theory )

is estimated to have almost snuffed us out.

Yellowstone would be about another order of magnitude just based on the size of its caldera.

What, me worry?
