Climate and environmental change, not human hunters, forced the extinction of mammoths, saber-toothed cats, and many other large creatures that once roamed Siberia, Alaska, and Canada, a new study suggests.

Scientists say the changes also spurred the near obliteration of massive herds of bison that once thundered through the region of Beringia about 37,000 years ago. A land bridge formed during the last ice age, Beringia joined Asia to Alaska and northwestern Canada.
