PhyloCode 2020: Naming the Tree of Life

Cantino, Philip [1].

An Introduction to the PhyloCode.

The first hardcopy version of the PhyloCode was published in 2020, marking the starting date for implementation of phylogenetic nomenclature (PN) as governed by this code. It was published with a companion volume called Phylonyms, in which 285 clade names were established. Under the PhyloCode, clade names are given phylogenetic definitions, which may have a minimum-clade, maximum-clade, or apomorphy-based structure. Some definitions also specify a crown or total clade. Taxonomic rank plays no role in naming, thereby eliminating a major source of taxon name instability. The PhyloCode does not govern species names and is designed to be used concurrently with codes of rank-based nomenclature (RBN) such as the botanical code. PN can be applied to clades of any size but may prove especially useful to: (a) stabilize the names of “higher taxa” (i.e., clades ranked higher than family in RBN); (b) name a series of nested clades between traditional ranks in RBN (e.g., between family and genus); and (c) accommodate fossils in a series of nested clades that include a total clade, one or more apomorphy-based clades, and a crown clade. The PhyloCode is administered and revised when needed by the International Society for Phylogenetic Nomenclature, which is seeking involvement by interested systematists.
