The theory predicts that preferred mate choices have evolved to focus on reproductive potential and reproductive investment of members of the opposite sex.
This theory predicts both intrasexual selection and intersexual choice due to differences in parental investment; typically there is competition among members of the lower investing sex (generally males) over the parental investment of the higher investing sex (generally females) who will be more selective in their mate choice.
Obviously, the so-called "zone of non-creepiness" is not a hard-and-fast rule; when you are adults of consenting age, no one's going to punish you for violating this arbitrary guideline.
Still, it's worth noting that at every age level, "men aren't even close to reaching the upper bound of the zone of non-creepiness," "According to the Standard Creepiness Rule, it'd be perfectly fine for a 30-year-old man to date a 45-year-old woman, but apparently 30-year-old men are already struggling with the idea of dating a 37-year-old," he writes.
As with all things, the half-plus-seven rule is better used as a rule of thumb than a strict law.
But even so, if you keep skirting the accepted minimum, you might consider widening the pool to older potential partners.
Divide your age by half and add seven years to get the minimum acceptable age for your romantic partner.
The study found that, as supported by other academic studies, most men preferred younger, physically attractive women, while most women, of any age, preferred successful, established men their age or older.Differences in age preferences for mates can stem from evolutionary mating strategies and age preferences in sexual partners may vary cross culturally.There are also alternative social theories for age differences in relationships as well as suggested reasons for 'alternative' age-hypogamous relationships.An overarching evolutionary theory which can provide an explanation for the above mechanisms and strategies adopted by individuals which leads to age disparity in relationships is called Life History theory Life History theory posits that individuals have to divide energy and resources between activities (as energy and resources devoted to one task cannot be used for another task) and this is shaped by natural selection.Parental Investment Theory refers to the value that is placed on a potential mate based on reproductive potential and reproductive investment.
