Yes... More recent genetic studies have shown that some clades of brown bear are more closely related to polar bears than to other brown bears,[14] meaning that the polar bear is not a true species according to some species concepts.[15] In addition, polar bears can breed with brown bears to produce fertile grizzly–polar bear hybrids,[13][16] indicating that they have only recently diverged and are genetically similar.[17] However, as neither species can survive long in the other's ecological niche, and with distinctly different morphology, metabolism, social and feeding behaviors, and other phenotypic characteristics, the two bears are generally classified as separate species.[17] en.wikipedia.org
