    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.
