International Code of Phylogenetic Nomenclature (PhyloCode)

Kevin de Queiroz is a vertebrate, evolutionary, and systematic biologist. He has worked in the phylogenetics and evolutionary biology of squamate reptiles, the development of a unified species concept and of a phylogenetic approach to biological nomenclature, and the philosophy of systematic biology. He received a B.S. in Biology from the University of California, Los Angeles (1978), a M.S. in Zoology from San Diego State University (1985), and a Ph.D. in Zoology from the University of California, Berkeley (1989). He was a Tilton Postdoctoral Fellow at the California Academy of Sciences and is currently a Research Zoologist and a curator of the collection of Amphibians and Reptiles at the National Museum of Natural History, Smithsonian Institution. He is a former president of the Society of Systematic Biologists and was the first president of the International Society for Phylogenetic Nomenclature. Philip D. Cantino received his Ph.D. from Harvard University and is currently Professor Emeritus in Environmental and Plant Biology at ohio University. His primary interests are angiosperm systematics (with emphasis on the phylogeny and taxonomy of Labiatae) and phylogenetic nomenclature, an alternative to traditional biological nomenclature that is designed to name the parts of the tree of life by explicit reference to phylogeny. He is an active member of the Committee on Phylogenetic Nomenclature.
