During human evolutionary history, there were "trade-offs" between expending time and energy on child-rearing and mating, so both men and women evolved conditional mating strategies guided by cues signaling the circumstances. Many short-term matings might be successful for some men; others might try to find and keep a single mate, investing their effort in rearing her offspring. Recent evidence suggests that men with features signaling genetic benefits to offspring should be preferred by women as short-term mates, but there are trade-offs between a mate's genetic fitness and his willingness to help in child-rearing. It is these circumstances and the cues that signal them that underlie the variation in short- and long-term mating strategies between and within the sexes.
在人类进化史上，在抚养子女和交配方面投入时间和精力存在“权衡”，因此男性和女性都进化出了受暗示环境的线索引导的条件性交配策略。对一些男性来说，许多短期交配可能会成功；另一些男性可能会试图寻找并留住一个伴侣，将精力投入到抚养她的后代上。最近的证据表明，具有向后代传递遗传益处特征的男性作为短期伴侣应该更受女性青睐，但伴侣的遗传适应性和他在抚养孩子方面的意愿之间存在权衡。正是这些情况以及暗示它们的线索构成了性别之间和性别内部短期和长期交配策略差异的基础。
