男性生殖器表现出由性选择驱动的不同进化模式。相比之下，对于许多分类群体来说，女性生殖器相对统一，其进化模式在很大程度上尚未探索。在这里，我们量化的变化，在整个onthophagine蜣螂的女性生殖器的形状，并使用新的比较方法来对比他们的分歧率与男性生殖器。正如预期的那样，男性生殖器的形状比自然选择的特征--前胫骨--分化得更快。值得注意的是，女性生殖器形状的变化速度几乎是男性生殖器形状的三倍。我们的研究结果消除了女性生殖器不表现出与男性生殖器相同的分化进化模式的概念，并表明女性生殖器通过其在女性选择中的作用进行性选择。虽然男性生殖器的形状是已知的，以响应性选择迅速演变，相对较少的女性生殖器形状的演变所知。在这里，作者表明，在所有的食粪甲虫中，雌性生殖器的形状比雄性生殖器的形状分化得更快。
Male genitalia exhibit patterns of divergent evolution driven by sexual selection. In contrast, for many taxonomic groups, female genitalia are relatively uniform and their patterns of evolution remain largely unexplored. Here we quantify variation in the shape of female genitalia across onthophagine dung beetles, and use new comparative methods to contrast their rates of divergence with those of male genitalia. As expected, male genital shape has diverged more rapidly than a naturally selected trait, the foretibia. Remarkably, female genital shape has diverged nearly three times as fast as male genital shape. Our results dispel the notion that female genitalia do not show the same patterns of divergent evolution as male genitalia, and suggest that female genitalia are under sexual selection through their role in female choice. Although male genital shape is known to evolve rapidly in response to sexual selection, relatively little is known about the evolution of female genital shape. Here, the authors show that across onthophagine dung beetles, female genital shape has diverged much more rapidly than male genital shape.
