If it'd been said 40 years ago that many persons are genetically predisposed towards homosexuality we'd have all laughed. Now we know it's true. Could there also be a genetic predisposition for some adults to seek out children as sexual partners? If so that may explain why "treating" such offenders rarely works. Next question would be was there ever a period during human evolution where procreation at the earliest possible moment was necessary to the survival of the species? Could men compulsively seeking sex with pubescent girls and/or committing forcible rape be the genetic holdover from ancient times? At least in some instances?
