No, that's the one...
I thought it was undetermined whether they could recover DNA at the time of the article, so that's why I was asking if anyone had heard?
The odds of a globally destructive volcano explosion in any given century are extremely low, and no scientist can say when the next one will occur. But the chances are five to 10 times greater than a globally destructive asteroid impact, according to the new British report.
The next super eruption, whenever it occurs, might not be the first one humans have dealt with.
About 74,000 years ago, in what is now Sumatra, a volcano called Toba blew with a force estimated at 10,000 times that of Mount St. Helens. Ash darkened the sky all around the planet. Temperatures plummeted by up to 21 degrees at higher latitudes, according to research by Michael Rampino, a biologist and geologist at New York University.
Rampino has estimated three-quarters of the plant species in the Northern Hemisphere perished.
Stanley Ambrose, an anthropologist at the University of Illinois, suggested in 1998 that Rampino's work might explain a curious bottleneck in human evolution: The blueprints of life for all humans -- DNA -- are remarkably similar given that our species branched off from the rest of the primate family tree a few million years ago.
Ambrose has said early humans were perhaps pushed to the edge of extinction after the Toba eruption -- around the same time folks got serious about art and tool making. Perhaps only a few thousand survived. Humans today would all be descended from these few, and in terms of the genetic code, not a whole lot would change in 74,000 years...

Ahh, I thought they didn't find any dna in the soft tissue, it was mostly just cell structure.
And I knew about the human bottle neck. our species has a very shallow genepool. An African man and an Eskimo woman are more genetically similar than two male gorillas of the same species that live on opposite sides of the same mountain.
It also explains why humans are so sickly compared to other animals - as i've explained to people - having sex with someone of the same ethnic group would prolly be regarded by other critters an incest!

[B] We'll all know soon enough anyway...

Do you know something we don't? Because if you're referring to death, I must tell you right now that I am going to live forever. ;)
