the peak of their fertility and reproductive value, while the minority of them is already experiencing intense and progressive decline in fertility. Similarly, the majority of women who did not desire children are past their fertility peak and the minority of them is currently at the beginning of their greatest fertile period. Finally, women who did not desire children are 10% more of older age than their partners when compared to women who desired children. Preference for older male partners could be related to their greater possession of resources and greater ability to transmit culture for children than younger partners, whereas for women who did not desire children, there is less concern about having younger partners. When it comes to the other 13 traits, all of them appear to be equally indicative of parental investment and culturally valued. Good cook and housekeeper, organized and refined are traits that both allow for the ability to take care of women and children, but are also fruit of an increasing cultural value attributed to men who are able to perform domestic tasks. Good social class and hardworking are traits that indicate the possibility of providing resources for woman and children, however at the same time, they do not indicate guarantee of actual investment being performed. Emotional stability and maturity, kind and understanding, sociability, inspiring personality, creative and artistic, good conversationalist, same religious and political beliefs are generic traits that tend to inhabit an imaginary of cultural idealization. A partner in possession of these traits is, apart from potentially able to invest in women and children, also culturally attractive. In this sense, it would be erroneous to say that selecting a male partner who possesses certain traits is an entirely cultural or evolutionarily selected behavior. In both groups compared, women have selected male traits that are indicators of both male parental investment and genetic quality, but also of cultural value. However, results showed that partners of women who desire children tend to possess more traits directly related to the ability and tendency of practicing parental investment and of genetic quality than partners of women who do not desire children. On the other hand, when it comes to male traits that are equally indicative of parental investment and culturally valued, there have been no significant differences between selection criteria of women who desire and who do not desire children. It is therefore possible to conclude that evolutionarily selected female psychological mechanisms regarding partner selection do currently manifest as fruit of an indissociable junction between culture and nature, what makes them not exclusively instinctive, but rather incorporated to a conscious net of thoughts, functioning according to current cultural context. It is intended that conclusions reached in the present work help weaken what is known as nature- culture dualism, thus defining an evolutive process as not solely biological nor solely cultural. The process of psychological evolution and its behavioral products are therefore simultaneously biological and cultural, in an intrinsically connected way. R eferences R éférences R eferencias 1.
