Study Notes
Levels of Biological Classification
- Domain: The broadest classification category, encompassing all forms of life; it consists of three domains: Archaea, Bacteria, and Eukarya.
- Kingdom: A primary grouping within the domain that includes major divisions of life; examples include Animalia, Plantae, Fungi, and Protista.
- Phylum: A significant taxonomic group within the kingdom, categorizing organisms based on major body plans or structural features; examples include Chordata for vertebrates.
- Class: Subdivision of phylum, consisting of one or more orders; it organizes related orders into higher-ranked categories, such as Mammalia for mammals.
- Order: A taxonomic rank that groups together families sharing common characteristics; an example is Carnivora, which includes families like Felidae (cats) and Canidae (dogs).
- Family: A classification level that groups one or more genera that are closely related, defining common traits and ancestry; for instance, Hominidae encompasses humans and their ancestors.
- Genus: A classification that includes closely related species, serving as a way to group organisms that share significant similarities; an example is Canis, which includes domestic dogs and wolves.
- Species: The most specific classification category, defining a group of organisms that can interbreed and produce fertile offspring; for instance, Canis lupus refers specifically to gray wolves.
