What Killed the Great Beasts of North America?

Posted by Unknown on from the mostly-spears dept.

sciencehabit writes "Until about 11,000 years ago, mammoths, giant beavers, and other massive mammals roamed North America. Many researchers have blamed their demise on incoming Paleoindians, the first Americans, who allegedly hunted them to extinction. But a new study points to climate and environmental changes instead. The findings could have implications for conservation strategies, including controversial proposals for 'rewilding' lions and elephants into North America."

    People killed them. Either by direct means or global warming.

    Or, I blame God.

    Is this to say that the Earth's climate has gone through natural changes over the centuries? Warming and cooling? All by itself?! I thought global warming - I mean - climate change - was caused by man burning fossil fuels.
