Will someone please inform the arrogant human-hating jerks like Jared Diamond? That's where he lost me in "Guns, Germs and Steel." What a crock! If humans did it why did we only go after the humungous-sized critters that could do us serious harm, while leaving most animals under 200 pounds alone? That's always seemed upside-down to me. Science marches on.
I'll bet that woodpecker in Arkansas knows where to find one.
Climate change, not hunters, killed ancient Australia's giant kangaroosCold, arid climates of the last ice age have been identified as a likely cause, casting doubt on the alternative hypothesis which blames human hunters... The largest marsupials weighted up to 2.5 tonnes - heavier than a four wheel drive car. Giant kangaroos were at least 1 m taller than the biggest kangaroos today. "They all became extinct, with the red kangaroo the largest marsupial to survive beyond the ice age. The reason for their extinction has long been debated" said Dr Matt Cupper of the School of Earth Sciences at the University of Melbourne. Dr Matt Cupper from the University of Melbourne and Ms Jacqui Duncan from La Trobe University revisited an archaeological site discovered at Lake Menindee on the Darling River in the 1930s where evidence of human hunting of the large animals had been argued to occur... "We determined that there is no evidence of humans butchering the marsupials. People were not even at the scene of the crime, with the oldest evidence of humans at the site at least 10,000 years after the giant mammals went extinct," said Ms Jacqui Duncan of the Archaeology Program at La Trobe University. "The animals probably died of starvation during drought around 55,000 years ago," she said.

Are you sure? I heard it was Bush's fault.
More confirmation of what we've long believed. Megafauna have mega-appetites and need more food than smaller (and smarter omniverous) critters like us. Climate affects food sources for grass-eaters and their predators. The fact that animals roughly 250 pounds and under survived and the mega-beasts didn't supports the new theory IMO.
SUV's were.
Bump.
