As I explained to Bob Comer, the hinnie (jack donkey/mare breeding) is
rare, but it does occur.

I think anyone would be surprised to learn that mule deer and whitetail
deer are the same species.

Have you ever heard of "ring speciation", Gary? Adjacent species
within the ring (think of trees ringing a mountain) can interbreed, and the
result is viable and fertile. But the next species over may or may not be
able to interbreed with species 1. By the time you go around the mountain,
the two adjacent species cannot interbreed.

IANAE, but even I can locate many examples of interbreeding among species
which create new life, and I don't have to look very far.
