“…Second, because women's reproductive value declines steeply over the life course, men will prefer cues indicating a woman's physical ability to reproduce-such as youth and beauty-more than will women (Symons, 1979). There is to date a great deal of evidence to support these predictions, including numerous studies documenting sex differences in preferences for these traits across many populations and using a variety of methods (Buss, 1989a(Buss, , 1989bBuss & Barnes, 1986;Buunk, Dijkstra, Fetchenhauer, & Kenrick, 2002;Hatfield & Sprecher, 1995;Khallad, 2005;Li, Bailey, Kenrick, & Linsenmeier, 2002;Lippa, 2007;Shackelford, Schmitt, & Buss, 2005;Stewart, Stinnett, & Rosenfeld, 2000;Zeh & Smith, 1985). In fact, so often has it been reported that men consider physical attractiveness more importantly in a long-term partner than do women and that women consider access to resources more importantly than do men that these sex differences are beginning to be treated as truisms (e.g., Greitemeyer, 2007;Koyama, McGain, & Hill, 2004;Wiederman & Allgeier, 1994).…”
