In biology, taxonomy (from Ancient Greek τάξις () 'arrangement', and -νομία () 'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. For quite some time now the scientific community has accepted that similarity does not necessarily reflect kinship (i.e., evolutionary relationship), one of the basic principles of phylogenetic systematics (Hennig, 1966), which remains a key component for molecular species delimitation and taxonomy (Gómez-Daglio & Dawson, 2017). k j ?
