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
17. 4 Domains and Kingdoms Classification is always a work in progress. – 1866: all singlecelled organisms moved to kingdom Protista Plantae Animalia Protista
17. 4 Domains and Kingdoms Classification is always a work in progress. – 1938: prokaryotes Animalia moved to kingdom Monera Plantae Protista Monera
17. 4 Domains and Kingdoms Classification is always a work in progress. – 1959: fungi moved to own kingdom Plantae Animalia Protista Monera Fungi
17. 4 Domains and Kingdoms Classification is always a work in progress. – 1977: kingdom Animalia Monera split into kingdoms Bacteria and Fungi Archaea Plantae Protista Archea Bacteria
17. 4 Domains Kingdoms The threeand domains in the tree of life are Bacteria, Archaea, and Eukarya. • Domains are above the kingdom level. – Carl Woese based on r. RNA studies of prokaryotes – domain model more clearly shows prokaryotic diversity
17. 4 Domains. Bacteria and Kingdoms • Domain includes in the kingdom Bacteria. –one of largest groups on Earth –classified by shape, need for oxygen, and diseases caused prokaryotes
17. 4 Domains. Archaea and Kingdoms • Domain includes in the kingdom Archaea. – cell walls chemically different from bacteria – differences discovered by studying RNA – known for living in extreme environments prokaryotes
17. 4 Domains. Eukarya and Kingdoms • Domain includes eukaryotes. –kingdom Protista all
17. 4 Domains. Eukarya and Kingdoms • Domain includes eukaryotes. –kingdom Plantae all
17. 4 Domains. Eukarya and Kingdoms • Domain includes eukaryotes. –kingdom Fungi all
17. 4 Domains. Eukarya and Kingdoms • Domain includes eukaryotes. –kingdom Animalia all
17. 4 Domainsand Kingdoms • Bacteria 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
