WASHINGTON — Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests.
The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday.
The report notes that a separate study by researchers at Stanford University estimated the number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the early Stone Age.

It was the SUV’s; (vide Flintstones).
Bush’s Fault.
I thought this was caused by the Toba volcano eruption.
Floods, droughts, hurricanes, tornados, earthquakes, volcanos, tsunamis; the earth has been trying to kill us for >100,000 years. It’s time we returned the favor.
There were was a housing bubble and a rice shortage at the time.
Gee, how did such a tiny group of humans manage to cause a worldwide drought?
A little setback now and then tends to cull the herd. We’re overdue.
This is a green weenie’s fantasy come true.
LOL!
So we were an endangered species due to global climate change. I say we put humans on the Endangered Species List. Then it will be illegal to kill humans in their embryonic form.
Yep.
Should have called GEICO.
Does this mean we should all put "African-Americans" down as our race????
I guess some drivers refused to retrofit their 68,003BC Hummer H2s with modern pollution controls, leading to this environmental disaster...
Though the year can never be precisely determined, the season can: only the summer monsoon could have deposited Toba ashfall in the South China Sea, implying that the eruption took place sometime during the northern summer.[7] The eruption lasted perhaps two weeks, but the ensuing "volcanic winter" resulted in a decrease in average global temperatures by 3 to 3.5 degrees Celsius for several years. Greenland ice cores record a pulse of starkly reduced levels of organic carbon sequestration. Very few plants or animals in southeast Asia would have survived, and it is possible that the eruption caused a planet-wide die-off. There is some evidence, based on mitochondrial DNA, that the human race may have passed through a genetic bottleneck within this timeframe, reducing genetic diversity below what would be expected from the age of the species. According to the Toba catastrophe theory proposed by Stanley H. Ambrose of the University of Illinois at Urbana-Champaign in 1998, human populations may have been reduced to only a few tens of thousands of individuals by the Toba eruption.[8]
Ethanol.
Agreed!
“The human population at that time was reduced to small isolated groups in Africa, apparently because of drought,.....”
Natural causes rather than Dem/Leftist-Greenie induced causes.
