You can be a novel "superman" and it makes no difference if you do not pass the genes on.

More genes passed on is more "fit."

Natural selection "rewards" nothing at all. It just is.

But now we go in circles. Reproduction is meaningless if the organism does not survive to maturation, let alone successfully find a mate. A 'novel superman' will likely survive to pass on his genetic material.
