| 再生是生物体丢失的组织或器官重新生长和修复的过程，是生物科学的本质问题之一。再生现象在生物界中广为分布，但不同生物的再生能力却存在着巨大差异。虽然近年来再生的分子和细胞机制取得了显著的研究进展，但驱动物种再生能力多样性形成的遗传机制尚不明确。海洋多毛类因其多样且快速演化的再生能力和简单线性的分节结构成为研究再生演化的极佳类群。本文首先从生态和演化生物学的角度综合分析了多毛类再生的特点、进一步总结细胞和分子来源以及再生性状多样性，然后分析了印太交汇区的海洋多毛类再生性状的特点以及外在多圈层因素对再生性状的潜在驱动效应，并就未来的发展趋势提出了建议。 |

| Abstract: |
| Regeneration, the ability to re-grow and repair lost tissues or organs, is one of the essential issues of biological sciences. Regeneration is widely distributed in animals but varies dramatically within or among animal phyla. Recent findings have identified key cellular and molecular principles underlying animal regeneration. However, the genetic mechanism driving the formation of species regeneration diversity is still unknown. Due to their diversity of regeneration ability, rapid gain and loss on phylogeny, and relatively simple segmented body plan, marine polychaete has been recognized as one of the excellent models to study the evolution of regeneration. We first summarize here recent advances in the regeneration evolution of marine polychaete in the context of ecology and evolution biology. We further review the cellular and molecular basis of regeneration, as well as the diversity of regeneration characteristics. In addition, we analyze the characteristics of marine polychaete regeneration traits in the Indo-Pacific Convergence Region, the potential driving effects of multi-circle factors on regeneration traits, and put forward suggestions on future trends. |
