And 48,000 single British women are actively seeking men with a failed marriage behind them."The Daily Mail cites Paul Mc Cartney’s third wife Nancy Shevell as a puma.Shevell is 17 years younger than the former Beatle.But, ultimately, women continue to push back on old taboos and seek out the romantic partners of whatever age they want.
There are also social theories for age differences in relationships as well as suggested reasons for 'alternative' age-hypogamous relationships.
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. Relationships with age disparity of all kinds have been observed with both men and women as the older or younger partner.
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.
However, human males tend to have more parental investment compared to mammal males (although females still tend to have more parental investment).
Concepts of these relationships, including what defines an age disparity, have developed over time and vary among societies.
Differences in age preferences for mates can stem from evolutionary mating strategies and age preferences in sexual partners may vary cross culturally.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.The study found very few instances of older women pursuing much younger men and vice versa. It's also a slang term for a woman's dating life and, more specifically, the age of the partner she seeks. Demi Moore, in an interview with W magazine in March 2010 (at age 47), expressed her displeasure with the cougar label and said, "I'd prefer to be called a puma," referring to her (now defunct) marriage to Ashton Kutcher who is 16 years younger than Moore.However, there are two conflicting definitions of a puma (as the term refers to women) and the word appears to have different meanings in the U. Despite Moore's attempt to use the terms interchangeably, a puma is widely regarded as a woman under 40 who prefers younger men while the cougar label is applied to women in their 40s and 50s who seek out younger male companions who are at least 10 years younger and often half their age.Within sexual selection Darwin identified a further two mechanisms which are important factors in the evolution of sex differences (sexual dimorphism): intrasexual selection (involve competition with those of the same sex over access to mates) and intersexual choice (discriminative choice of mating partners).
