摘要:

物种形成研究是人们关于新物种如何产生和维持的思考和探索,是进化生物学最重要的组成部分之一。对物种形成方式、生殖隔离产生过程及其内在遗传机制的探究和揭示,是物种形成研究领域的重要命题和主要研究内容,也是认识和理解自然界中物种多样性现象的关键线索和重要依据。本文聚焦于动物类群,首先介绍了目前人们关于物种概念的不同定义,在此基础上,围绕动物物种形成方式、生殖隔离分子机制等所取得的研究进展和重要突破进行阐述,并分析了目前动物物种形成相关研究的局限;最后,探讨了今后动物物种形成研究中潜在的新机遇和新突破。

Abstract:

Speciation research represents our thinking and exploration about how new species are generated and maintained, and it is one of the most important parts of evolutionary biology. Revealing new species formation modes, processes of reproductive isolation establishment and their intrinsic genetic mechanisms, are not only important issues and primary tasks in the field of speciation, but also the key clues for our understandings about the species diversity in nature. Here, by focusing on animal groups, we first introduced different definitions of species concept, and then summarized present research progress and important breakthroughs made in the speciation modes and molecular mechanism of reproductive isolation. We also pointed out some limitations in current studies. Finally, we discuss the potential opportunities and new breakthroughs that can be made in the future studies of animal speciation.

Key words: species, speciation, interspecific hybridization, reproductive isolation, genomes
