None of this means the mind, if it did evolve for survival, is totally unreliable for ascertaining the world around us and making reasoned guesses about the future. We all do that every day - monkeys included. My dog believes in the power of barking – she has tested it empirically and found it to be true…
Beyond this, animal husbandry is objectively tried and true, scientifically testable and falsifiable. It works. Reduce the meaning of "human" to "just another animal", and eugenics is fair game, and the scientific data is well supported. Eugenics is only abhorrent to those who recognize that there is something transcendently special about humans.
Science is about coming up with theories and testing to see if they match reality. That is how we have advanced so far in knowledge the last 300 years. We humans. We animals. For unless you are a plant or virus, you ARE an animal.
And Christians have believed in using reason since when Jesus walked the earth. It is a pity to see some here reject it as possible.
