男性的性选择特征可以通过不同的机制进化：引人注目且色彩缤纷的装饰品通常通过性间选择进化，而武器通常通过性内选择进化。与鸟类相比，雄性装饰品在哺乳动物中很少见，这导致人们认为雌性配偶选择通常在该类群的性状进化中发挥很小的作用。支持这一观点的是，当哺乳动物身上出现装饰品时，它们通常表明社会地位，并且是雄性之间竞争的产物。然而，这种普遍的哺乳动物模式可能不适用于恒河猴（Macaca mulatta）。该物种的雄性表现出明显的肤色，但这种表现与优势等级无关，因此不太可能是由于雄性之间的竞争而进化的。在这里，我们研究了圣地亚哥岛自由放养恒河猴种群中雄性颜色表达是否影响雌性对雄性的生育能力。我们收集了 24 只成年雄性在交配季节高峰期的主导地位和年龄各不相同的面部图像，并将这些图像建模为恒河猴的视觉感知。我们还记录了女性对这些男性的社会性行为。结果显示，与浅粉色的雄性相比，深红色的雄性受到更多雌性的性诱惑。结合之前的结果，我们的研究表明，男性的彩色装饰品更有可能是性间选择的产物，而不是性内选择的产物。由于恒河猴具有雄性间竞争的特殊特征，这种情况尤其如此。
Male sexually-selected traits can evolve through different mechanisms: conspicuous and colorful ornaments usually evolve through inter-sexual selection, while weapons usually evolve through intra-sexual selection. Male ornaments are rare among mammals in comparison to birds, leading to the notion that female mate choice generally plays little role in trait evolution in this taxon. Supporting this view, when ornaments are present in mammals they typically indicate social status and are products of male-male competition. This general mammalian pattern, however, may not apply to rhesus macaques (Macaca mulatta). Males of this species display conspicuous skin coloration, but this expression is not correlated to dominance rank, and is therefore unlikely to have evolved due to male-male competition. Here, we investigate whether male color expression influences female proceptivity towards males in the Cayo Santiago free-ranging rhesus macaque population. We collected face images of 24 adult males varying in dominance rank and age at the peak of the mating season, and modeled these to rhesus macaque visual perception. We also recorded female socio-sexual behaviors towards these males. Results show that dark red males received more sexual solicitations, by more females, than pale pink ones. Together with previous results, our study suggests that male color ornaments are more likely to be a product of inter- rather than intra-sexual selection. This may especially be the case in rhesus macaques due to the particular characteristics of male-male competition in this species.
