That's an impressive level of hubris. I hope you're aware that the extent to which a gene can propogate is only loosely correlated with subjective metrics like "fitness" and "superior" traits on to it's host organism. Otherwise, we wouldn't have crippling genetic disorders around after nearly 4 billion years of evolution.
Also, can we please oh please not project this liberal meme of the "free market" on to Nature. Nature doesn't have "better" or "worse" ideas and it certainly doesn't have markets - at least till we came around.
