The best-known examples of this process are the polar bear-grizzly hybrids, sometimes referred to as grolar or pizzly bears, four of which have been shot by hunters in recent years; genetic testing indicated that one of them was a second-generation animal. Weve known about pizzlies for quite some time, but their occurrence may be more common with ongoing Arctic warming, explains Larisa DeSantis, associate professor of biological sciences at Vanderbilt University and co-author of the study, in the video below.

But it seems to have happened only occasionally, which suggests to some that natural climatic fluctuations, in the form of advancing and retreating glaciers, pushed the bears together, encouraging intermixture.

Polar bears diverged from brown bears less than 500,000 years agonot long at all on an evolutionary timescaleand the two animals retain enough genetic similarity that they can interbreed and produce fertile offspring. In the mid-20th century, the influential evolutionary biologist Ernst Mayr argued that species arise only when individuals become isolated somehow from others of their kind.
