Biological classification of a chicken

Archaeopteryx is a genus of early bird that is transitional between feathered dinosaurs and modern birds.

Aves or birds is a class of animal. Animals or animalia is a kingdom on the domain Eukaryote.

Biological classification categorized LIFE into:

  • domain

    • (e.g. eukaryote)
  • kingdom

    • (e.g. animalia)
  • phylum

    • (e.g. chordata)
  • class

    • (e.g. aves)
  • order

    • (e.g. gamefowl or galliformes)
  • family

    • (e.g. phasianidae)
  • subfamily

    • (e.g. phasianinae)
  • genus

    • (e.g. gallus)
  • species

    • (e.g. gallus gallus or red junglefowl)
  • subspecies

    • (e.g. Gallus gallus domesticus or chicken)
    • (e.g. Gallus gallus _______  or gamecock)

In biological classification, subspecies (abbreviated “subsp.” or “ssp.“; plural: “subspecies”) is either a taxonomic rank subordinate to species, or a taxonomic unit in that rank. A subspecies cannot be recognized in isolation: a species will either be recognized as having no subspecies at all or two or more (including any that are extinct), never just one.

Organisms that belong to different subspecies of the same species are capable of interbreeding and producing fertile offspring, but they often do not interbreed in nature due to geographic isolation or other factors. The differences between subspecies are usually less distinct than the differences between species, but more distinct than the differences between breeds or races (races can be assigned to different subspecies if taxonomically different). The characteristics attributed to subspecies generally have evolved as a result of geographical distribution or isolation.
