Shift in diet allowed gray wolves to survive ice-age extinction
April 12, 2021 – Gray wolves are among the largest predators to have survived the extinction at the end of the last ice age around11,700 years ago. Today, they can be found roaming Yukon’s boreal forest and tundra, with caribou and moose as their main sources of food.
A new study led by the Canadian Museum of Nature shows that wolves may have survived by adapting their diet over thousands of years—from a primary reliance on horses during the Pleistocene, to caribou and moose today. The results are published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology.
