Answer 2

This may be a stupid question, but why is it that different species have different numbers of chromosomes, and how did that number change in the course of evolution? I know hybridisation can increase the chromosome count, but that's more of a plant thing: not so common among animals, and even the occasional doubling/removal of a chromosome in sexual reproduction don't satisfactorily explain how we got from N chromosomes in our hypothetical common ancestor (whatever N may be) to e.g. 46 in humans, 78 in dogs, 8 in fruit flies, etc.
