Just the other day I saw a short episode or polar bears swimming from block of ice to block of ice.
Polar bears the scientist said don't like to swim. I wondered if they will evolve and not become extinct as some scientists fear. Same goes for the penguins.

Ineresting. So since the bears already know how to swim they will survive right? Perhaps the lighter bears will survive over the heavier ones?
