'Once you can't find anyone from your own species to mate with, you perhaps lower your standards'
Whatever happened to romance?
There's now a contest on to think up clever names for the new sub-species - pizzly, grizzlar, and grolar are all doing the rounds amongst zoologists. Some people are even worrying that the purity of the polar bear volk might be at risk, as global warming brings more and more grizzly bears into their traditional territory and sets the scene for more unions:
If global warming is driving grizzlies farther north into polar bear territory, as some locals and scientists believe, there's a possibility that polar bear genes may disappear as the two species interbreed.
"Polar bears could lose their distinction," [Petkau] says.
"The trickle of grizzlies going north is turning into a stream. The hybrid event might be more common than we know."
