Minimise the reductions. Even if you want to commit mass genocide, you need to be picky. Evolution cannot result in revolution, or you're going to go an negative downspiral. First acquire statistics- those without special skills, diseases that are hazardous without counteractive alleles all need to go. If you want flaws, go to the people who can maintain it.

Then make sure the environment is suitable for growth. I see how wasteland appeals to you but if you don't have a suitable flow of genes and variation, your species will not be able to sustain itself. A strong species is one that can go through anything.

Am I supposed to go on with just the evolutionary details or also go into the behavioural conquest ones?
