^^^ Yes, it's scientific data, since the ash from the Yellowstone is found all around the world. And yes, we can do something about it if we manage to run away on time with our families from the most endangered areas. :)
1) There are more supervolcanoes on earth than the one under Yellowstone.
2) One of the previous eruptions of those almost wiped out humanity. There were just a few hundreds (some say 2,000) specimens left. This genetic bottleneck has been shown by worldwide DNA research.

I hear Istockphoto is getting a spaceship ready to blast off on a moments notice. But only exclusives can get on board. Can you imagine a world only populated by Itsock exclusives and the Istock staff? Shudder!
(who says this thread can't be about stock?) :D

Never underestimate the Canadian Space Program, eh.

Genetic Bottleneck, that sure explains a bunch of things.

Here I thought we were all descendants from multiple mutant generations of Australopithecus afarensis from Ethiopia and Kenya!

Meanwhile if it's not for the next few thousand years, I'm not going to get excited.  ;D

Caucasians seem to be leftovers from a few that survived the last ice age in caves in Anatolia and Spain. This genetic bottleneck explains the high genetic similarity between most humans nowadays since in those periods, not the classical Darwinian natural selection but genetic drift was the name of the game.

There have been several migration waves from East-Africa along the highway of the Nile along the Middle East and the Southern Asian shores, up till Australia. All these settlements except the ones of the last wave died out. One of the early waves remained in Australia (but their breadcrumbs going there were wiped out) as the aboriginals which are genetically quite different from current Asians.

Also don't forget the non-HSS (Homo Sapiens Sapiens) strains like the Neanderthals that coexisted with HSS in Europe till just 30,000 years ago. They were probably a leftover from a very early migration. HSS only migrated (the Out of Africa theory) to Europe/Asia a mere 150K years ago.
Western Africans also are genetically more different from the rest as they have been trapped under the Sahara and by the dense rain forest in Central Africa. Their only serious migration was the slave trade to the Americas.

The Asian eye folding may just be an amplification of a random mutation by genetic drift in a very small population. That drift stopped now since they are with 2.5 billion.
The skin albedo (melanin enrichment) is not really genetic but is steered by modulators of genes that can adapt 1000x more quickly than genes. It has been said any population migrating south will have a black skin within 15,000 years only (see the Tamils), and a white skin migrating north as skin albedo is a trade-off between death by skin cancer and death by lack of Vitamin D.

Boom diada boom diada, it's a wonderful world.  ;)

On topic - NO!

On the hijack, sure and keep in mind that cultures like those of Indonesia were sea based and they were disappointed when they found that the ocean was not endless. Spreading by sea is another later development. Walking across a land bridge, then the ice ages dividing the populations again.

Neanderthals always come to mind when I think of brute strength vs intelligence and adaptation.  :D But the answer is probably more in the line of tools which still divide cultures now.
