IQALUIT, Nunavut – Northern hunters, scientists and people with vivid imaginations have discussed the possibility for years.
Territorial officials seized the creature after noticing its white fur was scattered with brown patches and that it had the long claws and humped back of a grizzly. Now a DNA test has confirmed that it is indeed a hybrid â€” possibly the first documented in the wild.
“We’ve known it’s possible, but actually most of us never thought it would happen,” said Ian Stirling, a polar bear biologist with the Canadian Wildlife Service in Edmonton.
Polar bears and grizzlies have been successfully paired in zoos before â€” Stirling could not speculate why â€” and their offspring are fertile.
Breeding seasons for the two species overlap, though polar bear gets started slightly earlier.
