Preposterous!
Other than condescending sarcasm by supposed intellects, nothing specific to refute my simple point, that any difference in whole numbers of chromosomes where one gamete has an exclusive extra chromosome, there is no fertility. The only exceptions, which your intellectual friends missed, are duplicates shared by both gametes, such as in the Trisomy. Even then, fertility is very low, let alone how survival for such offspring was even lower for pre-modern times. With changes in numbers, we are not talking process; we are talking event. That means, all the time you want to give won't be a factor, other than repeated attempts to make it happen.

There was no indication in my description of what HAD to be there, only a description of what WAS there based on a lot of good evidence from planetary studies and the geological record.
So to answer your question, since it WAS there, the chances of it being there were exceedingly high.

Yet this proof has both escaped thousands upon thousands of Ph.D. level biologists, and more interestingly, professional anti-evolutionists who will throw every argument they can at the theory. Imagine the kind of unreflective self-importance it takes to hold that position.
Anyway, as others point out, a lot of wrong is packed into reasonably long post there. His core argument, however, is simply that it's not possible interbreeding between individuals with variations in their chromosomal numbers. This is just false. The failure of meiosis in mules has nothing to do with the different number of chromosomes per se. It is because the chromosomes are not homologous and so cannot form pairs. Otherwise the kind of scenario he thinks cannot happen happens in nature all the time. You know his artificial sounding conversation with a biology professor is fictional if only because a biology professor would easily be able to point that out.
