某种形式的再生发生在所有生命形式中,从单细胞生物延伸到人类。然而,考虑到系统发育的限制或惯性,以及形成这种模式的适应过程,再生能力在不同分类群中的分布程度很难确定。在这里,我们研究了再生的系统发育历史在两个群体中,这一特征已经得到了很好的研究:节肢动物和爬行动物。由于在这些群体中,自切常常与再生同时出现,因此我们对这两种特征进行了祖先状态重建,以更精确地评估它们起源的时间和这些特征共同进化的程度。利用祖先特征重建,我们发现节肢动物和爬行动物树的基部存在自切和再生。我们还发现,当自体切开术丢失时,它不容易重新进化。最后,我们发现再生的分布与自切密切相关,在爬行动物中比在节肢动物中更强。虽然这些模式表明,在广泛的系统发育尺度上解耦自切和再生可能是困难的,但现有的数据为它们的纠缠提供了有用的见解。最终,我们的重建为探索选择如何在特定谱系的再生丧失过程中发挥作用提供了重要的基础。
Some form of regeneration occurs in all lifeforms and extends from single-cell organisms to humans. The degree to which regenerative ability is distributed across different taxa, however, is harder to ascertain given the potential for phylogenetic constraint or inertia, and adaptive processes to shape this pattern. Here, we examine the phylogenetic history of regeneration in two groups where the trait has been well-studied: arthropods and reptiles. Because autotomy is often present alongside regeneration in these groups, we performed ancestral state reconstructions for both traits to more precisely assess the timing of their origins and the degree to which these traits coevolve. Using an ancestral trait reconstruction, we find that autotomy and regeneration were present at the base of the arthropod and reptile trees. We also find that when autotomy is lost it does not re-evolve easily. Lastly, we find that the distribution of regeneration is intimately connected to autotomy with the association being stronger in reptiles than in arthropods. While these patterns suggest that decoupling autotomy and regeneration at a broad phylogenetic scale may be difficult, the available data provides useful insight into their entanglement. Ultimately, our reconstructions provide important groundwork to explore how selection may have played a role during the loss of regeneration in specific lineages.
