Darwin admitted that the evolution of moral phenomena such as altruism and fairness, which are usually in opposition to the maximization of individual reproductive success, was not easily accounted for by natural selection. Later, authors have proposed additional mechanisms, including kin selection, inclusive fitness, and reciprocal altruism. In the present work, we explore the extent to which sexual selection has played a role in the appearance of human moral traits. It has been suggested that because certain moral virtues, including altruism and kindness, are sexually attractive, their evolution could have been shaped by the process of sexual selection. Our review suggests that although it is possible that sexual selection played such a role, it is difficult to determine the extent of its relevance, the specific form of this influence, and its interplay with other evolutionary mechanisms.
达尔文承认，自然选择很难解释利他主义和公平等道德现象的进化，这些现象通常与个体繁殖成功率的最大化相悖。后来，作者提出了其他机制，包括亲缘选择、包容适合度和互惠利他主义。在本研究中，我们探讨了性选择在人类道德特征出现中所起的作用程度。有人认为，由于某些道德美德，包括利他主义和善良，具有性吸引力，因此它们的进化可能受到性选择过程的影响。我们的综述表明，虽然性选择可能发挥了这样的作用，但很难确定其相关性的程度、这种影响的具体形式及其与其他进化机制的相互作用。
