Sorry, I thought it would be clear that "many" would be the right answer and that "many" was as likely as ... Hell, I can't think of anything.

Only an occasional instance of interbreeding can probably keep the two whale population sufficiently similar to remain the same specie. This is especially true if the difference in behavior between the whale populations are learned, not instinctive.

This brings up the following question: if two populations are genetically sufficiently similar such that it they were to interbreed, they would produce fertile offsprings. But the groups have different genetically driven behavior such that in real life, they never really actually mate. Are they already two species or not?

Story of my bloody life.
At the age of five, Skagra decided emphatically that God did not exist.  This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair.  Only Skagra responded to it by thinking, 'Wait a second.  That means there's a situation vacant.'

then your clearly not looking at the same fossil record Paleontologists are

I see, bald assertions without support.

And no, I made no claim about what you were "actually saying". Avoid knee-jerking, please.

An example of the timelines involved in any type of speciation which comes to mind is the cheetahs.
They believe the population dropped to as low as a few thousand.

In 10,000 years, they are all still identical twins. All capable of receiving skin and organ transplants without needing any anti rejection dosages.
Not sure what they mean by "abrupt" changes?
No God, No fear.
Know God, Know fear.

no you see facts with the support of the conclusion of an entire field of science an the experts involved oh and talk about the pot calling black I might add

and no I never said anything about actual anything
