Study Notes
Taxonomy Overview
- Taxonomy is the scientific method of classifying organisms, encompassing a structured hierarchy.
- Engaging with taxonomy enhances understanding of biological diversity and relationships.
Hierarchical Structure of Taxonomy
- The order of taxonomy includes: domain, kingdom, phylum, class, order, family, genus, and species.
- This system allows for organized classification and identification of living organisms.
Domain
- Highest taxonomic rank within the three-domain system established by Carl Woese.
- Domains categorize life forms into broad categories: Archaea, Bacteria, and Eukarya.
Kingdom
- A crucial taxonomic category that groups organisms with fundamental characteristics.
- In the five-kingdom classification, kingdoms include Animalia (animals), Plantae (plants), Fungi (fungi), Protozoa, and the unspecific group of eukaryotic algae.
Phylum
- Taxonomic rank situated below kingdom and above class.
- In botany, "division" was traditionally used; however, “phylum” is now the accepted term since 1993 for the International Code of Nomenclature.
Class
- A taxonomic rank positioned between phylum and order in the biological hierarchy.
- Classes may have a sub-level, termed subclass, which indicates a further division.
Order
- Positioned between class and family in the taxonomy hierarchy.
- Can include superorder (above order) and suborder (below order) categorizations for finer classification.
Family
- One of the eight primary taxonomic ranks, found between order and genus.
- Families can be further divided into subfamilies, offering additional classification layers in biological taxonomy.
Genus
- Taxonomic rank that includes species sharing common characteristics, situated above species and below family.
- A genus can consist of multiple species, helping to identify relationships among similar organisms.
Species
- Fundamental unit of biological classification, representing individual, identifiable organisms capable of interbreeding.
- Abbreviated as “sp.” for singular and “spp.” for plural references within taxonomy.
