DNA tests confirm strange bear was a hybrid

Northern Canadian hunters, scientists and people with vivid imaginations have
discussed the possibility for years.

Martell, left, is seen with a hybrid bear he shot while on a hunting
expedition on Banks Island, Northwest Territory, Canada. According to Dr.
Ian Stirling, researcher for the CWS, genetic tests showed the bear had a
polar bear for a mother and a grizzly bear for a father. Roger Kuptana,

But Roger Kuptana, an Inuvialuit guide from Sachs Harbour, North West
Territories, was the first to suspect it had actually happened when he proposed
that a strange-looking bear shot last month by an American sports hunter might
be half polar bear, half grizzly.
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 — 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 -
Stirling could not speculate why - and their offspring are fertile.
Breeding seasons for the two species overlap, though polar bear gets started
slightly earlier.
