Pizzly bears, also known as grolar bears and nanulaks, are a cross between a polar bear and a grizzly bear. However, the newer methods of genomics analyze thousands of sites in the genome, allowing the history of individual fragments of chromosomes to be traced back to particular populations (or species in the case of hybridization). He was looking for food, new territory . This is leading to a variety of consequences and changes. Since polar bears and grizzlies only diverged about 500,000 to 600,000 years ago, she said, their offspring are able to produce offspring as well.

Biologists have only documented polar and grizzly bears interbreeding in the wild in Canadas western Arctic.

When polar bears and grizzly bears mate, the hybrid is called a pizzly bear, or a grolar bear. This appears to reflect a process in which a population of polar bears was left behind as the species retreated northwards at the end of the last ice age, with male brown bears subsequently introducing genes from the adjacent mainland, but female brown bears being generally unable or unwilling to swim across several kilometres of open ocean to reach the islands (thus the lack of exchange of mitochondrial DNA). Although pizzly bears are not currently considered a distinct species, they are considered to be a subpopulation of either polar bears or grizzly bears. With several suspected sightings and eight confirmed cases,[3] theories of how such hybrids might naturally occur have become more than hypothetical.
