There's rarely a point to asking why something "didn't" happen. There's often no answer. From an evolutionary perspective, if a mutation offers no advantage to the perpetuation of the species, it is unlikely to perpetuate.

If we all had pointy ears, someone would probably be on the internet asking why we don't have round ears.
