Abstract

|
In species delimitation, a formidable goal in the discipline of systematic biology, we identify and describe species morphologically and ecologically based on phenotypic data. Efficient genotyping technologies produce genetic and genomic data with relative ease, which promotes species discovery and validation using genotype data. For the last two decades, we have seen the development of species delimitation methods based on genetic distances and phylogenetic trees using genotype data. However, speciation processes via evolutionary relationship among species were mostly divorced from species delimitation. Recent approaches to drawing species boundaries use multi-locus sequence data to account for evolutionary processes including speciation and gene flow. They allow us to learn of jointly speciation and species delimitation, leveraging computational and statistical techniques developed in population genetics and phylogenetics. Here, we review the recent progress in the development of species delimitation using genotype data and discuss the future outlook for the research of developing species delimitation methods.
