The hump is where a mass of muscles attach to the bear's backbone and give the bear additional strength for digging.

Amidst much controversy, the bear has since been returned to Martell. While there have been several pizzly bear cubs born in captivity over the years, sadly only a handful of them survived to adulthood, apparently due to their genetic makeup. The following year Ramona once again gave birth to Snowys babies. The original parent species typically have their own unique adaptations that are specialized for their respective environments. And, as they spend more time together, the likelihood of them interbreeding becomes higher. One camera trap showed a polar bear and black bear pass by within three hours of each other. Pizzly is . This makes some biologists believe grizzlies could take over populations of polar bears through one-way genetic flow. The evolution of bears is fascinating. Earlier this month, hunter Didji Ishalook shot a white bear in the northern Canadian territory of Nunavut which experts thought was a polar-bear-grizzly hybrid. Polar bears, who, except for pregnant females, dont hibernate, are known to breed out on the sea ice in March and April.

Polar bears typically rely on sea ice to hunt for seals, which make up the vast majority of their diet. The most recent example of temperature- mediated hybridization is between polar bears ( Ursus maritimus), and grizzlies ( Ursus arctos) in a hybrid tentatively referred to as a "pizzly" or "grolar" bear. The other four wild hybrid bears were second-generation pizzly bears, which means that their DNA is 75% grizzly, and 25% polar bear.
