Discovered a new species of bear

It is a crossing of the Arctic white bears with grizzly bears. It is a hybrid that now appears in more and…
many areas of Alaska and Western Canada.
Last week, a looks like a strange bear was shot dead by a hunter in the Νουβανούτ (Nunavut), a remote area around the Hudson Bay (Hudson Bay) in Canada. Her head was big, like a bear grizzly, but the coat of white. At present, there is a genetic testing, but the researchers seem to have come to the conclusion that this is still a hybrid.
The scientific manuals they say that the two genres are not supposed to reside in the same environment. Polar bears are marine mammals, whereas the grizzly is not.
But as the Arctic warms due to climate change, the sea ice is shrinking and the tundra is extended, the disparate populations of bears are found, the bears are mating and according to the Washington Post, created a new genre, with the ability to reproduce.
This is called a flexible choice of partner. The bears choose to mate with the best possible partners than to not mate at all, and that’s because they share nearby territories, and because they are the descendants of a common ancestor.
The intersections found in Alaska and Canada is not genetic abnormalities. Scientists have found the hybrid to islands in southeast Alaska, where bears that seemed to belong to the species of the grizzly, and they had DNA of a polar bear. This proves that the sporadic crossing of the bears is a phenomenon known for decades, reports Stephen Άμστρουπ (Steven Amstrup) chief scientist at Polar Bears International.
The Άμστρουπ studying bears in the Arctic since the 1970s and played a big role in the spread that the bear is an endangered species in the past decade. He and a few other experts about this new relationship as more beneficial for the grizzlies than polar bears. This is because there are more grizzlies than polar bears and because the ground is expanding, while the polar bears is shrinking due to melting of the ice.
All of the hybrids analyzed had a grizzly fathers. This occurs because the grizzly males roam to “occupy” new territory and come into contact with a receptive female polar bears. The female grizzlies tend not to be very far removed from the area, while the male polar bears do not usually invade the environment of the grizzly.
The polar bears need the ice, as there are seals and walruses eat. Do not hibernate, and do not travel south of the tundra. The grizzlies, historically, rarely dare to go into the north woods. The permanent layer of ice is too cold for them and sink into the snow easily. (Unlike the polar bears have feet that act as snowshoes).
Hybrids are “part of the normal evolutionary process,” said Andrew Ντερόσερ (Andrew Derocher, professor of biological studies at the University of Alberta. If, however, the ice disappeared, “we will not have a grizzly, the polar bears in this region. If you turn the clock ahead a few decades or even a century, you probably don’t even exist bears”.
