TAXONOMY THE TREE OF LIFE EUKARYOTA This domain includes all of the plants, animals, and fungi, and some single-celled organisms. Eukaryotes are distinguished by their complex cells, which contain a membrane-enclosed nucleus. Humans Homo sapiens The creatures most familiar to us, Our species, primates in the animals, are members of the Animalia kingdom of the Animalia same kingdom. Eukaryota, is thought to have Fungi Mosquito Red first evolved in Africa about Pufferfish Junglefowl Roundworm Mouse 200,000 years ago. Genetically, Amoebozoa Chimpanzee our closest living relative Plantae is the chimpanzee. Archaeplastida Schizosaccharomyces pombe ARCHAEA Saccharomyces cerevisiae BACTERIA Caenorhabditis briggsae Caenorhabditis elegans Eremothecium gossypii These single-celled prokaryotic organisms often Chromalveolata Dictyostelium discoideum These single-celled prokaryotic organisms were among Cyanidioschyzon merolae live in extreme environmental conditions. Once Excavata Arabidopsis thaliana the first life forms to appear on Earth. Often spherical, Plasmodium falciparum considered to be Bacteria, these microorganisms Cryptosporidium hominis rod-like, or spiral in shape, these microorganisms Thalassiosira pseudonana Oryza sativa Anopheles gambiae Drosophila melanogaster Takifugu rubripes Danio rerio are now recognized as a separate domain of life.

Oral traditions of taxonomy Woese defines the Archaea Scientists refer to a specific life form using its predate writing and were first used when human ancestors described different food sources, predators, as separate domain of life, Genus and species classifications. This naming and medicinal or poisonous plants. The advent of writing enabled more detailed, recorded taxonomies. introducing the three-domain technique is called binomial nomenclature. system used today.
