  1. Starter #1Stamping cover page Scientifically describe two ways animals are different from plants. Scientifically describe two ways animals are different from bacteria.

  2. Introduction to Classification Chapter 17 Sections 1-3 Pages 336-350

  3. Biodiversity • Ecologists have classified over 2 million species • Many more to be discovered • Taxonomy: The science of describing, naming, and classifying organisms into a taxonomic system • Taxon: Any particular group within a taxonomic system

  4. Life is organized into increasingly specific groups

  5. Levels Domain Kingdom Phylum Class Order Family Genus Species Specificity

  6. Mnemonic to remember order • D • K • P • C • O • F • G • S

  16. Classifying humans • Domain: Eukarya • Kingdom: Anamalia • Phylum: chordata • Class: Mamalia • Order: Primates Family: Hominidae Genus: Homo Species: Sapien

  17. Three Domains • Created based on rRNA Evidence • Three Domains include six Kingdoms • Domain Bacteria (Prokaryotes) • Domain Archaea (Prokaryotes) • Domain Eukarya (Eukaryotes)

  18. KINGDOM EUBACTERIA • unicellular prokaryotes • true bacteria

  19. KINGDOM ARCHEABACTERIA • unicellular prokaryotes • chemosynthetic • extremophiles

  20. KINGDOM PROTISTA • Heterotrophic and autotrophic eukaryotes • unicellular or multicellular • Ex. kelp

  21. KINGDOM FUNGI • Heterotrophic eukaryotes • Absorb nutrients from surroundings • Ex. Yeast, mold, mushrooms, athlete’s foot

  22. Kingdom Plantae • Multicellular • Eukaryotes • Autotrophic by photosynthesis • Ex. Mosses, ferns, conifers, flowering plants

  23. KINGDOM ANIMALIA • Eukaryotic • All multicellular • Heterotrophic

  24. Six Kingdoms

  25. Binomial Nomenclature • How scientists name species • Invented by Carolus Linnaeus

  26. Binomial Nomenclature • How scientists name species • Invented by Carolus Linnaeus • Scientific (species) Name • Genus Name + species name • Written in italics • Genus is always capitalized • https://www.youtube.com/watch?v=tYL_8gv7RiE

  27. Value • Clarity • Binomial names avoid confusion created when using common names to refer to a species. • Example: In English-speaking parts of Europe, the bird called a "robin" is Erithacus rubecula. In English-speaking North America, a "robin" is Turdus migratorius.

  29. SYSTEMATICS • The goal is to classify organisms in terms of their natural relationships • Uses similarities in appearance, embryos, chromosomes, proteins, and molecular molecules (DNA & RNA) • Two types: phylogenetics and cladistics

  30. PHYLOGENETICS • Phylogenetics: the analysis of the evolutionary or ancestral relationships among taxa • Based on common ancestors Phylogenetic Tree

  31. Phylogenetic Trees • Uses chromosomes and molecular molecules such as DNA, RNA, and proteins

  32. CLADISTICS • Uses shared and derived characteristics as the criteria for grouping taxa • Ex. feathers unique to birds
