Last Woolly Mammoths 'Died Of Thirst'

One of the last known groups of woolly mammoths died out because of a lack of drinking water, scientists believe. The Ice Age beasts were living on a remote island off the coast of Alaska, and scientists have dated their demise to about 5,600 years ago.

They believe that a warming climate caused lakes to become shallower, leaving the mammoths unable to quench their thirst. Some lakes were lost to the ocean, and as salt water flowed into the remaining reservoirs, freshwater diminished further.
