Study Notes
Species Concepts
- The Morphological Species Concept defines species as groups that can be morphologically distinguished from one another.
- The Biological Species Concept defines species as groups that can interbreed and produce fertile offspring.
Phylogenetic Nomenclature
- The Phylogenetic Species Concept defines species as the smallest identifiable monophyletic group.
- Phylogenetic nomenclature uses monophyletic groups for defining taxon names.
- The International Society for Phylogenetic Nomenclature (ISPN) regulates phylogenetic nomenclature currently.
- In phylogenetic nomenclature, a taxon name refers to a specific monophyletic group.
- A clade is another term for groups that consist of an ancestor and all its descendants in phylogenetic nomenclature.
- A full circumscription of a taxon in phylogenetic nomenclature requires a detailed description of the monophyletic group, including its characteristics and relationships.
