Evolution doesn't work that way. It doesn't decide that something is better, then evolve toward it. If a given mutation doesn't occur, it doesn't happen.
True, but if we evolved from little rat creatures or something similar then it seems likely that our proto-primate ancestors at some point went from claws to nails. So the question then is why were nails advantageous enough to become the norm?
