Asked by Ana

Are black bears and white bears the same species? why or why not?
Answered by Dr Russ
Do you mean polar bear?

A definiton of species is that they do not interbreed. There is an example of a brown/polar bear cross.

I believe brown and polar bears are closely related. Not sure how close related black and polar bears may be.
