"Then how did they differentiate enough to become two distinct species if they shared the same environment? The initial genetic changes should not have been enough to prevent inbreeding for several generations, at least. So how DID they differentiate?"

The same ways ANY two species differentiate ( look up, allopatric, peripatric, parapatric and sympatric speciation).

If you accept that wolves and coyotes have a common ancestor, you should be able to answer your own question.

Any two species? Nope.

That doesn't hold true for the very first two species of life. Impossible, mathematically, for the first species of life to cross-breed.
