  1. SYSTEMATICS

  2. Linnaean Taxonomy • Carolus Linnaeus organized plants and animals into 7 hierarchical categories. • Kingdom • Phylum • Class • Order • Family • Genus • Species Animalia Chordata Mammalia Primates Hominidae Homo Homo sapiens

  3. Linnaean Taxonomy • Scientific (species) name • Genus name • Specific epithet (species identifier) • Written in Latin • Dead, but universal scholarly language • Italicized or underlined • Ex: Canis familiaris Mycobacterium leprae

  4. Systematic Taxonomy “Our classifications will come to be genealogies” • Using… • Morphology, embryology, paleontology, biochemistry

  5. Molecular Clock

  6. Systematic Taxonomy • Phylogenetic Tree • Depicts phylogeny of organisms

  7. Systematic Taxonomy • Ancestral Characters • Heterotroph, eukaryote • Derived Characters

  8. DIY Phylogenetic Tree

  9. Domains(Carl Woese, U of Illinois) • Three domains of living things • Reorganization: Archaea more similar to Eukarya based on molecular data Eukarya Protista, Fungi Plantae, Animalia Bacteria Archaea Prokaryotes Eukaryotes Membrane, DNA, & ribosomes Progenote
