Lowering his standards......
Maybe the grizzly just liked the polar bear...maybe it was true love....maybe he likes polar bears better than grizzlies....cause you know...all the grizzly chicks were making fun of him...yeah, that's it, and the poor grizzly was kinda sad and the polar bear was all nice to him...and they fell in love....
That's kinda neat...to think that hybridization goes on in the wild. I really wonder how many more interspecies crosses there are out there in the wild
