Abstract

Dollo's law of irreversibility argues that evolution cannot revert to earlier states. It has remained controversial ever since its inception in the 19th century. Enabled by advances in phylogenomics and functional genomics, recent studies show that there are very likely some cases of 'breaking Dollo's law'. As post-genomic research grows from showing patterns to revealing processes, new emphasis is needed on the molecular mechanisms by which Dollo's law might be broken. Shifting the argument from 'if it happened' to 'how it happened' will provide richer understanding of organismal and evolutionary biology. Motivated by case studies and novel avenues to test trait loss and regain, we outline a set of alternative hypotheses to be evaluated and what the outcomes tell us about evolution.

后基因组时代的多洛不可逆定律。
多洛不可逆转定律认为,进化不可能恢复到早期状态。自 19 世纪提出以来,该定律一直饱受争议。在系统发生组学和功能基因组学的推动下,最近的研究表明,很可能存在一些 "打破多洛定律 "的情况。随着后基因组学研究从显示模式发展到揭示过程,我们需要对打破多洛定律的分子机制给予新的重视。将论点从 "是否发生 "转移到 "如何发生",将为生物体和进化生物学提供更丰富的理解。在案例研究和检验性状丧失与恢复的新途径的推动下,我们概述了一系列有待评估的替代假说,以及这些假说的结果对我们进化的启示。

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
