I suggest you read the "natural selection is wrong thread" referenced earlier, and the paper referenced therein.
Obviously if the expected outcome of natural selection for a good deal of cases is that the less fit reproduce, then natural selection is invalidated as a means of reaching optimal fitness. It is there a means of reaching less then optimal fitness. It just depends on the scenario if natural selection leads to optimal fitness.
Obviously this mistake of survival of the fittest would never have been made if natural selection had been formulated individually in stead of comparitively.
After the mistake has been found out that the fittest don't actually survive, the next mistake to be found out is that populations actually go extinct.
10X each with probability of 0.00001 percent of reproduction
5Y each with probability of 0.00005 percent of reproduction
A huge 5 times more likely to reproduce advantage for Y variants!
Now what would differential reproductive success result in?
Maybe this should be covered by the theory of differential reproductive failure?.........
A word like "success" in a theory should make any science minded person sucpicious about the scientific merit of the theory.
But all discussed countless times before, as for example in the "natural selection is wrong" thread.
