New, though, is the recognition that some potential genetic diversity may exist in close relatives, in genomes once considered inaccessible. In 2006, testing the DNA of a unique-looking bear that had been shot near Sachs Harbour, Northwest Territories on Banks Island in the Canadian Arctic confirmed that polar bears can breed with brown bears to produce fertile grizzly-polar bear hybrids - which are named the grolar bear, pizzly bear, or nanulak.

They tend to inherit the tawny brown fur from their lion fathers and the dark stripes from their tigress mothers. Since then, the prevailing wisdom among evolutionary biologists has been that interbreeding the creation of hybrid offspring is a potentially lineage-ending mistake. The females wandered off and mated with the less-troubled species closer to shore. Javier Monzon, an evolutionary biologist at Stony Brook University, has found that Eastern coyotes living in areas with the highest densities of deer also carry the greatest number of wolf genes. While ligers are certainly something to marvel at, youll never found one outside of a zootheyre a man-made hybrid cross between a male lion and tigress, something that would never occur in nature.

Many of the species in the Heliconius genus originated as hybrids of other Heliconius species and are now reproductively isolated from their parent species. In fact, some ecologists believe this never would have occurred without the impact of climate change a warmer climate pushed Brown Bears further north and into more of the Polar Bears range, increasing the likelihood of contact. So the two bear species contacting to each other more frequently in recent decades, which resulted in more mating between them. In an exceedingly brief period, coyote, wolf and dog genes have been remixed into something new: a predator adapted to a landscape teeming with both prey and another apex predator, us. , specifically in zoos.
