Intercourse is part of parenting (although you can have intercourse without parenting, until recently humans couldn't parent with having intercourse)... but I get your point.
I wouldn't use the word, 'parenting' to refer to anything involving intercourse. Parenting is what you do for children once they're outside the womb. If you are sleeping with your co-parent, that's not part of parenting; it's just your relationship with another adult.
Quote:Modern society is screwing around with evolution. Stone Age humans had to have a lot more offspring. Lots of children died, and communities that didn't produce lots of offspring simply ceased to exist. It is only in recent history that human societies could tolerate adults that weren't reproducing.
Cultural evolution is part of evolution. Our brains and hands evolved the ability to make and refine tools and through the ages our ability to make and refine tools has evolved far beyond what most people's brains and hands can do by themselves from scratch, i.e. from raw materials.
We are still evolving to figure out how to temper our industrial evolution with our ability to foresee future/long-term effects of our industries. Just as we had to learn not to hunt herds to extinction once we figured out how to efficiently hunt as much game as possible, we also have to learn how not to harvest/use energy and other resources in ways that cause unsustainability.
So we use our brains not only to help our current offspring survive, but also to ensure that their offspring, and their offspring's offspring, and so forth all have the ability to live in ways that don't diminish future resources and thus the ability for future generations to have offspring as well.
