Females demonstrate a complementary 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.
As well as asking participants a number of questions on mate selection criteria, they also had to provide the oldest and youngest partner they would accept.
There are also social theories for age differences in relationships as well as suggested reasons for 'alternative' age-hypogamous relationships.
However, human males tend to have more parental investment compared to mammal males (although females still tend to have more parental investment).
Thus, both sexes will have to compete and be selective in mate choices.
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.
