摘要:

生物多样性的起源与进化是生命科学领域最重要的科学问题之一。多组学数据的积累和相关分析技术的发展, 极大地推动了人们对生物多样性起源与进化的理解和研究, 使得阐明生物进化事件发生的过程与机制成为可能。值此《生物多样性》创刊30周年之际, 本文简要回顾生物多样性起源与进化相关研究在近年来取得的重要研究进展, 以期帮助读者了解该研究方向的发展现状。过去10年中, 生物多样性起源与进化相关研究在生命之树重建、生物多样性时空分布格局、物种概念、物种形成与适应性进化以及新性状起源与多样化等方面取得了许多重要进展, 并在此基础上厘清了许多分类单元间的系统发育关系、揭示了生物多样性分布格局的部分历史成因、提出了新的物种概念和物种形成模型、阐明了新性状和新功能发生的部分分子机制。我们认为, 更精准地重建生命之树、深入挖掘基因组数据以及多学科交叉融合将是今后生物多样性研究的主要趋势。

Abstract

Aims: The origin and evolution of biodiversity is one of the most important scientific questions in the field of life sciences. The accumulation of multi-omics data and the development of related analytical techniques have greatly promoted our understanding and research on the origin and evolution of biodiversity, thereby making it possible to clarify the processes and reveal the mechanisms of biological evolution events. On the occasion of the 30th Anniversary of the inaugural of Biodiversity Science, this paper briefly retrospects the important research progress of the origin and evolution of biodiversity in recent years, aiming to help the readers comprehend the present development on this topic.
Progresses: In the past decade, research on the origin and evolution of biodiversity has made many significant advancements, including the reconstruction of the tree of life, the spatiotemporal distribution pattern of biodiversity, the concepts of species, speciation, and adaptive evolution, and the origin and diversification of new characters. Based on these advancements, phylogenetic relationships among many taxa were clarified; some historical causes of biodiversity distribution patterns were revealed; some new species concepts and speciation models were proposed; and some molecular mechanisms of new characters and functions were revealed.
Prospect: We believe that the more accurate reconstruction of the tree of life, in-depth mining of genomic data, and the multidisciplinary integration would be the main trends in biodiversity research.

Key words: biodiversity, speciation, new characters, origins, evolution
