动物生殖器的种间形态变异长期以来一直引起进化生物学家的关注,因为生殖器形态可能在物种边界的产生和/或维持中发挥作用。在这里,我们检查的起源和演变的生殖器变异的啮齿动物属Neotoma。我们测试了一种相对罕见的生殖器形式在肿瘤中只进化了一次的假设。我们使用四个线粒体和四个核标记来评估这一假设,通过建立一个系统发育框架来检查生殖器进化。我们发现β-纤维蛋白原基因的内含子7是肿瘤分化水平的高信息核标记,该基因座的进化速度比细胞色素b慢,但比12S快。我们使用最大简约和最大似然贝叶斯方法来估计瘤内的系统发育关系。我们的贝叶斯和简约性重建在很大程度上不同,但我们表明简约性分析可能受到长分支吸引力的影响。此外,在贝叶斯分析中,我们对肿瘤系统发育的估计在各种数据划分策略中保持一致。利用祖先状态重建,我们发现了具有相对罕见生殖形式的分类群的单一性。然而,我们也找到了支持共同生殖器形式独立进化的证据,并讨论了可能的潜在发育变化,这些变化可能有助于我们观察到的形态进化模式。
Interspecific morphological variation in animal genitalia has long attracted the attention of evolutionary biologists because of the role genital form may play in the generation and/or maintenance of species boundaries. Here we examine the origin and evolution of genital variation in rodents of the muroid genus Neotoma. We test the hypothesis that a relatively rare genital form has evolved only once in Neotoma. We use four mitochondrial and four nuclear markers to evaluate this hypothesis by establishing a phylogenetic framework in which to examine genital evolution. We find intron seven of the β-fibrinogen gene to be a highly informative nuclear marker for the levels of differentiation that characterize Neotoma with this locus evolving at a rate slower than cytochrome b but faster than 12S. We estimate phylogenetic relationships within Neotoma using both maximum parsimony and maximum likelihood-based Bayesian methods. Our Bayesian and parsimony reconstructions differ in significant ways, but we show that our parsimony analysis may be influenced by long-branch attraction. Furthermore, our estimate of Neotoma phylogeny remains consistent across various data partitioning strategies in the Bayesian analyses. Using ancestral state reconstruction, we find support for the monophyly of taxa that possess the relatively rare genital form. However, we also find support for the independent evolution of the common genital form and discuss possible underlying developmental shifts that may have contributed to our observed patterns of morphological evolution.
