Let an agent explain systematics and its methods, relay the relationship between taxonomy, phylogenetics and classification from biological sources, describe the subfields the registry aliases name, and distinguish systematics from taxonomy alone, from evolutionary biology broadly and from cladistics as one school.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain systematics and its methods, relay the relationship between taxonomy, phylogenetics and classification from biological sources, describe the subfields the registry aliases name, and distinguish systematics from taxonomy alone, from evolutionary biology broadly and from cladistics as one school.

The scientific study of the diversity of organisms and their relationships, encompassing taxonomy, the naming and classification of organisms, and phylogenetics, the reconstruction of evolutionary relationships, including phylogenetic systematics or cladistics, comparative phylogenetics that uses trees to study trait evolution, the classification of eukaryotes, animal phylogeny, and phylomemetics, which applies phylogenetic methods to cultural items; the registry places this sense within zoology.

What it is for: Classifying organisms by relationships.

It can be explain the field; relay methods; describe subfields; distinguish related fields.

Distinguishing features

Diversity and relationships

Taxonomy plus phylogeny

Tree-based methods

Many subfields

What it looks like

Not a visible object; phylogenetic trees and classifications.

Physical character

Hennig s Phylogenetic Systematics: 1950, English 1966 note

described species: about 2 million

eukaryote supergroups: several, revised regularly note

How it is recognised

Study of organismal diversity and relationships

Phylogenetics, phylogenetic systematics, comparative phylogenetics, classification of eukaryotes, animal phylogeny, phylomemetics

Taxonomy names and ranks; evolutionary biology is broader; cladistics is one methodological school

What the second pass must settle

  • Should phylogenetics and phylomemetics be separate primary entries?
  • How should biological sources be linked?
  • The registry entry has merged aliases naming methods, groups and a cultural application; should they be split off?
