Here is my theory for the monogamous instinct, indirectly inferred by the defensive reaction associated with crimes of passion. If you look at the past 10,000 years, the advantage of humanity was more connected to the brain than to genetics. Through language, education and now science, whatever we lack genetically, can be compensated for by the brain/mind. The modern medical mind is able to alter genetics, due to science, which is a product of the brain. It is hard to point out major genetic changes over the past 10,000 years, that can explain what the brain has accomplished. Show me the gene that put a man on the moon.

Animals are different than humans, in that their genetics lead, since their brains are wired into genetics. The brain has some liberty for adaptation but their pace of change is slow and very conservative.

That being said, an animal will benefit by promiscuity, because it will increase the genetic diversity. I agree with that, since their genetics is leading, and this will give a selective advantage via more genetic combinations. With the human mind leading the past 10,000 years, increased genetic diversity, all by itself, would not have allowed the same pace as the brain created. Selective advantage for humans, when civilization began, needed to be geared to the needs of the brain more than simple genetic diversity.

Something changed in humans so humans could better pass down more to the young brain than just genes.
