Darwinian evolution is useless when applied to modern humanity. There is no "survival of the fittest". Consider also that individual genetics are irrelevant to breeding success when put against external factors like security and wealth. Our knowledge and ideas are much more valuable to humanities survival than our individual genetics at this point.
I would also personally argue that once you gain the ability to modify the human genome any desire for classical evolution is deeply flawed. Relationships are largely a holdover from the evolutionary need to reproduce, although obviously it's good for our happiness and emotional state to satisfy those desires in our current form.
