由配偶选择驱动的性选择已经产生了自然界中一些最惊人的多样性，这表明人口水平的偏好应该是强大的，并且在许多代人中保持一致。另一方面，交配偏好是个体动物表型中最不可重复的组成部分，这表明在动物的一生中，一致性应该很低。尽管对性选择进行了数十年的深入研究，但多年来几乎没有关于偏好强度和一致性的信息。在这项研究中，我们展示了连续19年对一种野生青蛙进行的5,000多次交配选择测试的结果。结果表明，偏好是积极和强烈的，不同年份之间变化不大。尽管女性之间在偏好程度上存在很大差异，但这种一致性仍然存在。我们还认为，随着时间的推移，主要是感官开发的结果的人群中的配偶偏好可能比主要参与评估男性质量的偏好更稳定。
Sexual selection driven by mate choice has generated some of the most astounding diversity in nature, suggesting that population-level preferences should be strong and consistent over many generations. On the other hand, mating preferences are among the least repeatable components of an individual animal’s phenotype, suggesting that consistency should be low across an animal’s lifetime. Despite decades of intensive study of sexual selection, there is almost no information about the strength and consistency of preferences across many years. In this study, we present the results of more than 5,000 mate choice tests with a species of wild frog conducted over 19 consecutive years. Results show that preferences are positive and strong and vary little across years. This consistency occurs despite the fact that there are substantial differences among females in their strength of preference. We also suggest that mate preferences in populations that are primarily the result of sensory exploitation might be more stable over time than preferences that are primarily involved in assessing male quality.
