Love in the time of climate change: Grizzlies and polar bears are now mating

"Bears sharing both species’ DNA have been recorded several times over the past decade. So why are these two species linking up? It’s called flexible mate choice: The bears are mating with the best possible partners as opposed to not mating at all, and they’re mating because they share relatively close territories and the same branches of the same evolutionary tree."
