The Weather. Scientists say that climate change is driving the hybridization. This perhaps marks an evolutionary 180 from when polar bears and grizzlies diverged from a common ancestor hundreds of thousands of years ago, Vital Ground reported. Humans are doing a lot more than warming the planet, so hybridization is not the only issue that has the potential to decrease biodiversity. Sea ice concentrations have declined by 13 percent each decade since 1979 due to increasing global temperatures.

But Mr Servheen said not very much was known yet about these 'grolar' and 'pizzly' bears. These experiments demonstrate a strong correlation between the ability to exert self-control in children and their later success as adults. Arctic regions have warmed twice as fast as the rest of the world, so seasonal sea ice is also forming later in the fall and breaking up earlier in the spring.

Some interesting studies are also discussed which examine how lowering certain hormones affect libido and attachment. Polar bears really depend upon sea ice, theyve evolved with it and they arent built to live on the shore long-term, said Servheen. Polar bears have been around for a long time (first diverging from grizzlies 4-5 million years ago), surviving some very strong fluctuations of the environment, so its difficult to theorize how this could have happened without them "temporarily going extinct", but keeping their DNA within grizzly bears.
