The multiple applications of DNA barcodes in avian evolutionary studies.
DNA barcodes of birds are currently available for 41% of known species and for many different geographic areas; therefore, they are a rich data source to answer evolutionary questions. We review studies that have used DNA barcodes to investigate evolutionary processes in birds using diverse approaches. We also review studies that have investigated species in depth where taxonomy and DNA barcodes present inconsistencies. Species that showed low genetic interspecific divergence and lack of reciprocal monophyly either are the result of recent radiation and (or) hybridize, while species with large genetic splits in their COI sequences were determined to be more than one independent evolutionary unit. In addition, we review studies that employed large DNA barcode datasets to study the molecular evolution of mitochondrial genes and the biogeography of islands, continents, and even at a multi-continental scale. These studies showed that DNA barcodes offer high-quality data well beyond their main purpose of serving as a molecular tool for species identification.
