Amid climate change, the area of ice is shrinking, forcing polar bears to shrink their range and to cope with it, they have to forage in warmer regions of the earth.
“Polar bears tend to retreat to the mainland for food, surviving the melting ice caused by global warming. They have chosen the Alaskan grizzly as their companion in hopes of keeping their breed. Paleontologist Larisa DeSantis told Dailymail.
This combination will create a new species of bear capable of adapting to climate change against a backdrop of warmer global temperatures.
DeSantis believes the polar bears have become extinct due to their special diet, with gradually shrinking ice caps in the area they cannot move and force them to eat the food they used to eat before. They don’t like it.
With a long skull, they can easily dive into water and hunt seals, but because of this characteristic, they will be difficult to adapt to the bruise or hard
Unlike polar bears, grizzly bears are able to adapt well to hard foods due to their short cranial structure, as well as accept cadavers and coyce.
Global warming means grizzly bears will go north and compete directly with polar bears. However, a symbiosis is quite possible if they agree to mate and give birth.
For example, a rare hybrid bear captured in 2006 in southern Idaho demonstrated this symbiosis. The results of the DNA study showed that the bear’s father was a grizzly and the mother was a polar bear. They are known to scientists as Pizzly (Polar + Grizzly).
So far only eight cases of bears have been recorded, pizzly bears have characteristics of their parents including: predominantly white and brownish coat and a cross between polar bears and grizzly bears.
