I have this theory, which I'm pretty sure is right, but I could be wrong. Many of you are smarter than me, so maybe you could tell me where I'm wrong. Here it goes.

Throughout history, people were conceived either by consensual sex, or rape. Taking a random person today, their ancestors were conceived by X amount of consensual sex and Y amount of rapes. If there are no biases in sexual selection, ratio of X to Y should be roughly the same for all people today. However, not all men get equally selected for consensual sex, there are biases. One of the major biases in consensual sex that is not present in rape is beauty. Being beautiful is one of the major factors that helps you get chosen more frequently for consensual sex. Therefore, beautiful genes would get passed on in consensual sex more frequently than ugly genes, while we could assume both would get equally passed in rape situations. Although one could argue as well that beautiful people have had lower incentives to commit rape, since they could get consensual sex easily. With that, we could conclude that beautiful people today have lower percentage of rapes in their ancestors conceivings, and ugly people today have higher percentage of rape conceivings.

Am I wrong?
