Plot twist: every known polar-grizzly hybrid (aka grolar bear) in Canada’s western Arctic can be traced back to one wild female polar bear from 1989! Scientists thought there’d be more hybrids, but so far, just eight have been found—and they’re all family. As climate change pushes grizzlies and polar bears together, researchers are keeping an eye out for more of these rare, chocolate-colored cubs. Nature is full of surprises! #Science #grolarbear #wildlife
