Natural selection can explain “the survival of the fittest but not the arrival of the fittest.”
Let us give some thought to the Y chromosome of Drosophila melanogaster, that engaging fly which is the bond-servant of genetics.
As technology mimics nature, at what point might future investigators be unsure about natural versus intelligent causes?
