kissing cousins?

Chris Servheen, a bear biologist and Adjunct Associate Research Professor at the University of Montana, is among a group of scientists who believe climate change is causing the polar and grizzly bears to come into contact more often.

“As you know, as the climate warms there is less and less sea ice in the Arctic,” he said. “And also what’s happening is that grizzly bears seem to be moving further north, we’re seeing their range extend further north toward the coast of the Arctic both in Alaska and in Canada.”

“The result is you have polar bears spending more time on land and grizzly bears spending more time where polar bears might be, and so the result is that we’re seeing these occasional hybrids between two species.”
