LOS ANGELES, June 12 (UPI) -- A combination of climate warming, encroaching humans and habitat change saw woolly mammoths go extinct thousands of years ago, U.S. scientists say.
Although humans and mammoths co-existed for millennia, the shaggy giants disappeared from the Earth between 4,000 and 10,000 years ago, doomed by the same threats facing many species today, UCLA researchers reported Tuesday.
