Rule of dating girls younger
Age-disparity relationships have been documented for most of recorded history and have been regarded with a wide range of attitudes dependant on sociocultural norms and legal systems.
For example, different age preferences may be a result of sex differences in mate values assigned to the opposite sex at those ages.Male chimpanzees tend to prefer older females than younger and it is suggested that specific cues of female mate value are very different to humans.Buss attributed the young age preference for females to the cues that youth has.highlight that although long term mating relationships is common for humans, it is not characteristic of all mating relationships: there is both short term and long term mating relationships.Buss and Schmitt provided a Sexual Strategies Theory which predicts the two sexes have evolved distinct psychological mechanisms which underlie the strategies utilised for short and long term mating.Females demonstrate a complimentary pattern, being willing to accept considerably older males (on average 8 years older) and were also willing to accept males slightly younger than themselves (on average 5 years younger).
This is somewhat different to our close evolutionary relatives: chimpanzees.
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.
However, human males tend to have more parental investment compared to mammal males (although females still tend have more parental investment).
Thus, both sexes will have to compete and be selective in mate choices.
A study conducted by David Buss investigated sex differences in mate preferences in 37 cultures with 10,047 participants.
