Reply to comment by deadcommand 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 don't really see them falling into that pit. I read the question more in the following sense: If an individual randomly has additional or fewer chromosomes, and reproduction with all the other individuals having the standard number of chromosomes is difficult, then how come so many species did manage to reproduce after introducing or losing new chromosomes?
