If Dumbo was a bunny

I had a bunny with ears like this..not quite as big though. He would always trip on them. Or if he was running he would somersault across the floor. Definitely a disadvantage

Poor bunny.

Evolution doesn't have to be an advantage. Evolution relies on genetic mixups

I wasn't saying it seemed like it wouldn't exist. More like "if that poor bunny ever gets loose it's dying." I assume this whole shebang is the result of human intervention in the bunny's family tree.
