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
