報告摘要:

　　Species delimitation is a fundamental task in systematics and biodiversity research, yet it remains a challenging endeavor due to the complex nature of evolutionary processes and the limitations of traditional analytical techniques. Recent advances in machine learning (ML) have significantly enhanced the field of species delimitation by introducing powerful computational tools capable of analyzing complex, high-dimensional datasets. ML algorithms provide a flexible and scalable framework for identifying patterns in genomic and phenotypic data, overcoming many of the limitations associated with traditional taxonomic methods. This paper reviews current applications of ML in species delimitation, highlighting its capacity to resolve issues related to gene flow, incomplete lineage sorting, and cryptic diversity. We present simulation studies that demonstrate the effectiveness of ML approaches and discuss their advantages in improving the accuracy, objectivity, and efficiency of species boundary inference. Our findings underscore the transformative potential of ML in systematics and call for broader integration of these tools in taxonomic research.
