Polar bears are the largest bear species and are supremely adapted to their Arctic habitat, whether they are prowling the ice or swimming in the sea. 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. But it will be hundreds of generations before we really see a new type of bear., US ceases efforts to end global trade of polar bear parts, Original reporting and incisive analysis, direct from the Guardian every morning.

Scientists say that climate change is driving the hybridization. Reported first by Thred, according to researchers, rising global temperatures has forced the two species to congregate together and this frequency has now risen considerably, resulting in more interbreeding. So-called "pizzly" bears were first spotted in the wild in 2006. This is causing them to spend more time together, only increasing their chances of interbreeding. We interviewed our tech expert, Jaime Vazquez, to learn more about accessible smart home devices. Time spent in weightless conditions lead to serious bone loss and almost immediate and severe muscle atrophy.
