Reply to comment by Painting_Agency in Given that reproduction is difficult or impossible when both animals have different numbers of chromosomes, how did so many species evolve to have so many different numbers of them? by MercurioLeCher

I both like and dislike that. Because on the one hand, yeah, you’re not wrong. On the other, it feels a bit like it discourages exploration as a kind of “yeah it just be like that” sort of thing.

The thing is that with science we CAN explore how things happen. There isn't really a "why" in evolution though. I mean, there is a why in the proximal sense, but there's no plan. Alleles either propagate in a population or they don't. With good data analysis we can map how that happened, when it happened, and we can postulate and test what causes it to happen.
