Woolly mammoth walked far enough to circle Earth twice, study finds

Research into life of Kik adds weight to theory that climate change could have contributed to species' demise

He was huge, hairy and boasted two enormous tusks: researchers say they have discovered a woolly mammoth called Kik who traipsed almost far enough in his life to circle the Earth twice.

Experts say the work not only sheds light on the movements of the giant proboscideans, but adds weight to ideas that climate change or human activity may have contributed to the demise of most of the creatures about 12,000 years ago.
