Whether the pizzly population will actually increase is yet to be seen, as both bear species have adaptations best suited for their habitat. Africanized honey bees, also known as killer bees, are a hybrid between European and African honeybees. Related species are often geographically separate, which prevents intermixing; sister species that share habitats frequently evolve different markings, calls and behaviors through which they distinguish their own kind and avoid crossbreeding. Most hybrids are the offspring of two species in the same genus. In captivity, many bird hybrids exist, and the Catalina macaw is one of them. At one end of this canid continuum, there are wolves with coyote genes in their makeup; at the other, there are coyotes with wolf genes. Or as happened among the Galpagos finches, hybrids can facilitate genetic exchange and help parental species adapt to challenges.

The flexibility they can provide depends on the continued existence of at least two parental species, after all hardly a given for many creatures. The grolar bear is a direct consequence of climate change driving natural selection somewhat. Similarly, in 1880 in Canada, Col Samuel Bedson bred cows with American bison, creating another bovid hybrid known as a cattalo. Martell shot the animal (picture), the first recorded. This is pushing polar bears, which are particularly adapted to a diet of high-fat blubber and meat, further south out of their hunting zone in search of food, potentially altering their diets and consuming foods they are not well suited for, according to a study published in Global Change Biology. The abiding question is: Will hybridization further erode biodiversity, preserve it, augment it or some combination of all three? They also lie down with their hind limbs splay-leggeda distinctive polar bear pose. The Grants, who tell these stories in their new book, 40 Years of Evolution, saw hybridization help species adjust to new conditions.

In recent years, more than a half dozen pizzly bears have been discovered across Alaska and Canada. Fertile hybrid offspring, meanwhile, may face the problem of maladaption: Because the parent species have usually evolved to exploit different habitats, intermediate hybrids ought to be ill suited to the environs of both parents. But as permafrost rapidly melts and prey moves poleward into polar bear-inhabited coastlines, grizzlies are bumping into polar bears and mating with them. .

In these situations, the hybrids are often the result of the two bear species cohabitating in the same enclosures. But it does exist in captivity. We werent even sure if they are real or not until recently. One of the most famous cases also comes from Nunavut, but a decade earlier. Whether it be due to invasive species colliding with locals, habitat destruction, or being placed in captivity, new hybrid species are formed that would not have existed otherwise.
