But humans are social creatures with no natural predators, so female competition is more widespread – and demonstrative performance and display are more likely. Indeed, while visual manifestations of wealth are prevalent for both genders, women’s appearance is frequently more vivid (and more closely scrutinized).
因为雌性承担着繁衍后代的任务，外表不引人注目似乎是明智的选择——因此在自然界中这种现象也是比较普遍的。但人类是没有天敌的社会动物，因此存在着普遍的女性竞争——也更有可能出现炫耀性的行为和举动。其实，虽然炫富在男女两性中均颇为盛行，但女性的表现似乎更加生动（也更受人关注）。
