Abstract:
Taxonomy underpins all biological research, with implications for many basic scientific and applied fields. Insights into the stability or change of animal and plant guilds require species identification on a broad scale and biodiversity questions have become a major public issue. But this domes at a time when taxonomy is facing a crisis, because ever fewer specialists are available. Here, we explore the possibility of using DNA-based methodology to overcome these problems. The utility of DNA sequences for taxonomic purposes is well established. However, all current taxonomic approaches intend to use DNA, at best, as an auxiliary criterion for identifying a species or a taxon, but have not given it a central role. We propose a scheme in which DNA would be the scaffold of a taxonomic reference system, whilst maintaining the importance of the morphological information associated with whole specimens.
