Even modern humans are the product of genetic exchange with Neanderthals some 60,000 years ago. 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. A 2017 study in the journal Arctic indicated that eight hybrids had been born of a mother polar bear who mated with two grizzlies.
