Climate Change and the Mastodons

 Not man-made. From SciTechDaily:

In the first large-scale genetic study of American mastodons, published today in the journal, Nature Communications, researchers reconstructed complete mitochondrial genomes from the fossilized remains of 33 individual animals. The species went extinct approximately 11,000 years ago during the megafaunal extinctions that took out many of the large mammals such as mammoths, sabre-toothed cats, and giant ground sloths.

The mastodon was among the largest living land animals on Earth at the time, roaming from Beringia (present-day Alaska and the Yukon) east to Nova Scotia and south to Central Mexico. They were primarily browsers, living in swampy settings, eating shrubs, and low-hanging tree branches. (Read more.)
