Arguably in ancient society, two men fight, the stronger wins, thus the stronger mans genes were selected rather than the weaker man's,The stronger man is then able to pillage gold and take the woman of the weaker man, giving him a wife if he had not previously one, or two if he had one previously.
But this isn't rape. The woman will likely be thrilled to have a strong winner want to mate with her.
Arguably in modern society, if a country practiced 'forced eugenics, that required people of desirable genes have X many kids, and people of undesirable genes have less or no kids,Genetics of later generations would improve.
I guess the modern society is essentially doing the women's mate selection job, in your scenario. I'm not sure all of the mating would be rape (seeing as the people are of higher quality), but if someone was forced to breed in this scenario when they didn't want to, there would be an evolutionary advantage from rape.
A tenet of some religions I've heard, allow neither the husband nor wife to refuse their partner sex, even if they don't want it.One would suppose this would result in more children.
If your partner doesn't want to have sex with you, you're probably too ugly for them. Perhaps it's better for society you don't breed so you don't pollute the gene pool. Hence, this is an example of rape being an evolutionary disadvantage. More children doesn't necessarily equal better survival chance in the long run.
A tenet of some religions I've heard, disapprove of some aspects of modern medicine, resulting in death sometimes from situations where some medical practice might have saved.
Sounds like an evolutionary disadvantage to me.
