However, there are fewer and fewer biologists who practice traditional taxonomy, or the collection, description, naming and categorization of organisms through intense study of their physical attributes. In general, the field of taxonomy, or systematics as it is often called, has been leaning towards the molecular end of the spectrum since genetic technology matured in the late 1970s and 1980s, and traditional taxonomic skills have been dwindling as older taxonomic experts retire. Many taxonomists blend traditional methods, such as morphological and behavioral study, with modern molecular techniques, such as DNA sequencing, to fully characterize their pet taxa. But taxonomists like Cognato and Hulcr, who rely on fieldwork and morphological study as core aspects of their taxonomic work, appear to be slowly going extinct. - Todd Suomela
