Phylogenomic Species Delimitation Dramatically Reduces Species Diversity in an Antarctic Adaptive Radiation.

Systematic biology - 16 Dec 2021

Parker Elyse, Dornburg Alex, Struthers Carl D, Jones Christopher D, Near Thomas J

Abstract excerpt

Application of genetic data to species delimitation often builds confidence in delimitations previously hypothesized using morphological, ecological, and geographic data and frequently yields recognition of previously undescribed cryptic diversity. However, a recent critique of genomic data-based species delimitation approaches is that they have the potential to conflate population structure with species...
