Study Notes
Biological Taxonomy Overview
- Taxonomy is the science of classifying living organisms into hierarchical categories.
- The three-domain system of taxonomy includes Archaea, Bacteria, and Eukarya, established by Carl Woese.
Domain
- The highest taxonomic rank in the biological classification system.
- Represents broadest groupings of life forms.
Kingdom
- Ranks above phylum in Linnean taxonomy.
- Traditionally divides life into five kingdoms: prokaryotes, protists, fungi, plants, and animals.
Phylum
- A principal category in taxonomy ranking above class and below kingdom.
- Groups organisms sharing significant anatomical and genetic traits.
Class
- A taxonomic rank within biological classification.
- Positioned between phylum and order in the classification hierarchy.
Order
- A rank in biological classification, falling between class and family.
- Recognized by nomenclature codes to categorize organisms.
Family
- One of the eight major taxonomic ranks in biological classification.
- Positioned between order and genus, can be subdivided into subfamilies.
Genus
- A taxonomic category below family and above species.
- Comprises groups of species that share structural similarities or common ancestry.
Species
- The fundamental taxonomic category representing closely related organisms.
- Typically capable of interbreeding to produce fertile offspring, ranking below genus.
