One thing that really interests me is the more frequent mating of polar bears and grizzly bears in the wild. In theory, it's because their territories are starting to overlap more and more due to melting Arctic ice. The cross breeding had been done before in captivity, but they are finding the cross bred species in the wild with more frequency.
