Animals differ markedly in their ability to regenerate, yet still little is known about how regeneration evolves. In recent years, important advances have been made in our understanding of animal phylogeny and these provide new insights into the phylogenetic distribution of regeneration. The developmental basis of regeneration is also being investigated in an increasing number of groups, allowing commonalities and differences across groups to become evident. Here, we focus on regeneration in the Spiralia, a group that includes several champions of animal regeneration, as well as many groups with more limited abilities. We review the phylogenetic distribution and developmental processes of regeneration in four major spiralian groups: annelids, nemerteans, platyhelminths, and molluscs. Although comparative data are still limited, this review highlights phylogenetic and developmental patterns that are emerging regarding regeneration in spiralians and identifies important avenues for future research.
动物在再生能力方面存在显著差异，但对于再生如何进化仍知之甚少。近年来，我们对动物系统发育的理解取得了重要进展，这些进展为再生的系统发育分布提供了新的见解。越来越多的类群也在研究再生的发育基础，使得不同类群之间的共性和差异变得明显。在这里，我们关注螺旋动物门的再生，该类群包括动物再生的几个佼佼者，以及许多再生能力较为有限的类群。我们综述了四个主要螺旋动物类群（环节动物、纽形动物、扁形动物和软体动物）中再生的系统发育分布和发育过程。尽管比较数据仍然有限，但本综述突出了螺旋动物再生方面正在出现的系统发育和发育模式，并确定了未来研究的重要方向。
