Species and subspecies of bear known to have produced offspring with another bear species or subspecies include brown bears, black bears, grizzly bears and polar bears, all of which are members of the Ursus genus . Bears not included in Ursus, such as the giant panda, are probably unable to produce hybrids . Note all of the confirmed hybrids listed here have been in captivity (except grizzly / polar bear), but there have been hybrids in the wild . </P> <P> A recent study found genetic evidence of multiple instances and species combinations where genetic material has passed the species boundary in bears (a process called introgression by geneticists). Specifically, species with evidence of past intermingling were (1) brown bear and American black bear, (2) brown bear and polar bear, (3) American black bear and Asian black bear, (4) bears currently distributed in Asia (sloth bear, sun bear and Asian black bear). Overall, this study shows that evolution in the bear family (Ursidae) has not been strictly bifurcating, but instead showed complex evolutionary relationships . </P>
