It has seven terminal taxa. Suppose now, for instance, that taxon H is in fact a composite of terminals, also numbering seven. An operational taxonomic unit (OTU) is an operational definition used to classify groups of closely related individuals. The term was originally introduced in 1963 by Robert R. Sokal and Peter H. A.
