The PhyloCode, types, ranks and monophyly: a response to Pickett

摘要

A report from the First International Phylogenetic Nomenclature Meeting recently published in Cladistics conveys several misconceptions about the PhyloCode and presents an erroneous interpretation of discussions that took place at that meeting. Contrary to Pickett's assertions, the PhyloCode is designed to name clades, not paraphyletic groups; the rejection of ranks has never been a fundamental principle of phylogenetic nomenclature; and specifiers under the PhyloCode differ in several ways from types under rank-based nomenclature.
