Systematics

'Systematics is a biological discipline of classifying organisms. The aim is the determination of identities and inter-relationships at the species level, and of evolutionary relationships above the species level. Subdisciplines such as Phylogenetics and cladistics study the evolutionary relatedness among various groups of organisms. The correct application of scientific names is the field of the taxonomy, while the nomenclature determines the rules by which the application of scientific names to organisms is determined.
