Earlier this summer, reports surfaced that a pizzly was shot by a Candian hunter. Whereas a polar bear has an extended, sleek profile, the grizzly bear has a much rounder, thick head. Genomic studies of brown bears and polar bears have revealed that gene flow from polar bears into brown bears, but not the other way around, was widespread in time and space during the Pleistocene. Pizzly bears have adapted to Arctic conditions by mixing polar bear genes with brown bear genes, which makes them better hunters and could help increase the polar bear population in an ever-warming climate. He was also featured in The Journal of Heredity in February of 1950. The first pizzly bear was found in the wild in 2006. Polar bears have hollow hair follicles.

The cubs were called double hybrids since both of their parents were hybrids themselves. Grolar (where the father is a grizzly) and pizzly bears (where the father is a polar bear) were first confirmed as a hybrid species in 2006 through DNA testing of a specimen shot in the. If the father was a grizzly and the mother a polar bear, biologists have suggested they are called the grolar bear. These rare animals are found in the Arctic regions of northern Canada and Greenland, where they have adapted to life in the harsh, cold environments of the far north. And with that growing contact between the two species comes more mating, and therefore increased sightings of their hybrid offspring. There are nearly 2,000 different species! The mating season for the polar bear and the grizzly bear overlaps, increasing their chances of breeding. Although there is no scientific name for this hybrid of bears, this seems to be an appropriate name for their parentage. "Apex predators help stabilize ecosystems, and looking forward I really hope the Arctic still has a polar bear. Lance Craighead, a bear biologist and director of the Craighead Institute, a conservation biology organization focused on grizzlies, agrees.

Sadly, only one of Pokodiaks double-hybrid cubs survived. 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).

The egg is fertilized and then develops into a tiny blastocyst embryo. The other four were 75 percent grizzly and 25 percent polar bear, the result of the original two grizzly fathers mating with one of the first generation hybrid offspring. "We've known about pizzlies for quite some time, but their occurrence may be more common with ongoing Arctic warming," DeSantis said. The hunter had killed the bear thinking it was a polar bear, but officials noticed it had different features to a typical polar bear. This makes some biologists believe grizzlies could take over populations of polar bears through one-way genetic flow. Scientists at the time said that the only thing that made it special was that it existed. The USFWS imported eight female cougars from Texas, allowing them to mate with the panthers.
