People are not perfectly symmetrical (especially internally) and I suppose animals are like that too. But how does evolutionary biology explain how fiddler crabs have one claw very much bigger than the other. If one big claw is "good" wouldn't two big claws be "better"? Are there other species that are so blatantly externally asymmetrical?
