> If everything in reality is made from nails, then it makes sense to look for the hammer that hammered it in. Everything in human psychology was in fact molded through evolution, so of course it makes sense to look to evolution for potential answers.

What is the question and what are the possible answers? What difference would it make in our morals?

That sounds like the reverse of the good old "Well, if God does not exist, why don't you just kill random people, then?"

Anger and violence and rape and murder, are all bilogical and evolutionary based. So what?

> "If a culture artificially forces relationships to last by, say, heavily stigmatizing divorce, then of course that's going to override the "natural" course of events.

See the above argument, it changes nothing. And by the way, divorce is more normalized than ever and divorce rates are falling in the developed world.

On the countrary, if lustful love is just a chemical process that eventually wears off, you're better off not divorcing. If love was this astral magestic thing, then sure, divorce and pursue it.

People have this idea "yeah, but back then, there was no marriage and both men and women could just fuck arround".

Sure, some people did just like today, but back then, we lived in small groups, a coule hundred individuals, the opportunities to fuck around were not as great as today and there was no anonymity as today.

I've been 20 pumped with testosterone. Was it not for my religious education and moral sense, I would probably have slept with a lot more women. Between age 20-35 I think I only cried 3 times, when my grandparents died.

As my testosterone levels are declining, my emotions are coming back.

I'm still the same biological organism, evolution did not intend one course or the other. I just find a lot of satisfaction now from family life.

There is no contradiction or dilema for me. I do not feel oppressed by society or morals or biology.
