DNA evidence assists ice age extinction debate

The end of the Pleistocene epoch brought with it widespread extinctions of large mammals, such as saber-toothed cats and mammoths. Ancient bison, too, were threatened with elimination, but they managed to survive. The two leading theories of what caused the precipitous population drop focus on environmental shifts and pressure from human hunters.

A genetic analysis published in the current issue of the journal Science lends support to the hypothesis that climate change was the culprit.

A genetic analysis published in the current issue of the journal Science lends support to the hypothesis that climate change was the culprit.

That's gonna make the "tree huggers" unhappy, something that they can't blame mankind for!

I don't see how mankind COULD be to blame...back then, we had neither the inclination nor the means for the mass slaughter of large animals. Trying to kill a mammoth, for example, would have proven so dangerous we'd probably not risk doing away with too many...besides, they'd provide so much meat, you wouldn't need to.

Nature will always be far more deadly than humankind no matter what type of weapons we create although we can certainly cause horrific destruction and death, but to actually claim we caused extinction of these animals all these years ago is proposterous, we did not have the numbers or ability to accomplish such a horrific feat!
