As DeSantis says in the video, the two species are capable of reproducing offspring that are themselves capable of reproducing (most hybrids are sterile) because the two species only diverged around 500,00- 600,000 years ago. It was during that year that it was spotted in the wild. Weve known about pizzlies for quite some time, but their occurrence may be more common with ongoing Arctic warming, explains Larisa DeSantis, associate professor of biological sciences at Vanderbilt University and co-author of the study, in the video below.
