17.4 Domains and Kingdoms KEY CONCEPT The current tree of life has three domains.

17.4 Domains and Kingdoms Classification is always a work in progress. The tree of life shows our most current understanding. New discoveries can lead to changes in classification. –Until 1866: only two kingdoms, Animalia and Plantae Animalia Plantae

17.4 Domains and Kingdoms Classification is always a work in progress. The tree of life shows our most current understanding. New discoveries can lead to changes in classification. –Until 1866: only two kingdoms, Animalia and Plantae –1866: all single-celled organisms moved to kingdom Protista Animalia Protista Plantae

17.4 Domains and Kingdoms Classification is always a work in progress. The tree of life shows our most current understanding. New discoveries can lead to changes in classification. –Until 1866: only two kingdoms, Animalia and Plantae –1938: prokaryotes moved to kingdom Monera –1866: all single-celled organisms moved to kingdom Protista Animalia Protista Plantae Monera

17.4 Domains and Kingdoms The tree of life shows our most current understanding. New discoveries can lead to changes in classification. –Until 1866: only two kingdoms, Animalia and Plantae Classification is always a work in progress. –1938: prokaryotes moved to kingdom Monera –1866: all single-celled organisms moved to kingdom Protista Monera –1959: fungi moved to own kingdom Fungi Protista Plantae Animalia

17.4 Domains and Kingdoms The tree of life shows our most current understanding. New discoveries can lead to changes in classification. –Until 1866: only two kingdoms, Animalia and Plantae Classification is always a work in progress. –1938: prokaryotes moved to kingdom Monera –1866: all single-celled organisms moved to kingdom Protista –1959: fungi moved to own kingdom –1977: kingdom Monera split into kingdoms Bacteria and Archaea Animalia Protista Fungi Plantae Archea Bacteria

17.4 Domains and Kingdoms The three domains in the tree of life are Bacteria, Archaea, and Eukarya. Domains are above the kingdom level. –proposed by Carl Woese based on rRNA studies of prokaryotes –domain model more clearly shows prokaryotic diversity

17.4 Domains and Kingdoms Domain Bacteria includes prokaryotes in the kingdom Bacteria. –one of largest groups on Earth –classified by shape, need for oxygen, and diseases caused

17.4 Domains and Kingdoms –known for living in extreme environments Domain Archaea includes prokaryotes in the kingdom Archaea. –cell walls chemically different from bacteria –differences discovered by studying RNA

17.4 Domains and Kingdoms Domain Eukarya includes all eukaryotes. –kingdom Protista –kingdom Plantae –kingdom Fungi –kingdom Animalia

17.4 Domains and Kingdoms Bacteria and archaea can be difficult to classify. –transfer genes among themselves outside of reproduction –blurs the line between “species” –more research needed to understand prokaryotes bridge to transfer DNA
