ScienceDaily (Jan. 12, 2011) Men With Macho Faces Attractive to Fertile Women, Researchers Find
When their romantic partners are not quintessentially masculine, women in their fertile phase are more likely to fantasize about masculine-looking men than are women paired with George Clooney types.
But women with masculine-looking partners do not necessarily become more attracted to their partners, a recent study co-authored by a University of Colorado at Boulder researcher concludes.
Meanwhile, a man’s intelligence has no effect on the extent to which fertile, female partners fantasize about others, the researchers found. They say the lack of an observed “fertility effect” related to intelligence is puzzling.
The findings augment the emerging understanding of how human sexual selection evolved over time, and how the vestiges of that evolution are evident today.
