that takes me back to memories of my highscool biology class. i had a teacher who was really theatrical and would always delve into examples of concepts and give analogies. when it came time to talk about sexual reproduction, mitosis and meiosis and the like, he began talking about the various "difficulties" of sexual reproduction. He mentioned the usual - being too genetically distant, having a physical blockade appear between two groups, having a female prefer males with certain features, etc....
and then we got around to what he called "mechanical difficulties"
as he put it, "some parts just dont fit some places". for his example, he invoked a large male great dane and a small female chihuahua. you could tell there was tension behind his voice lol, that was an interesting class and his personality made it even moreso
