“Usually hybrids aren’t better suited to their environments than their parents, but there is a possibility that these hybrids might be able to forage for a broader range of food sources,” Larisa DeSantis, a paleontologist and associate professor of biological sciences at Vanderbilt University, told Live Science. While polar bears have longer skulls, better for grabbing seals, “…their molars are smaller than is typical for their body size because all they eat is blubber all day. Grizzlies, on the other hand, can eat whatever they want. We don’t know yet, but perhaps the intermediate skull of the pizzly could confer a biomechanical advantage.”
