Presentation Transcript

  1. Wake-up • Explain a vestigial structure. • Explain the difference between divergent and convergent evolution.

  2. Questions are on the white board.

  3. Classification of Life Christopherson

  4. Group the beads in the bag on your desk.Briefly explain how your categorized them in your notes

  5. What is Classification? Method by which biologists group and categorize organisms.

  6. What is Taxonomy? Science of Classification

  7. History of Classification: Aristotle Grouped all living things into two main groups: Plants and Animals He further divided animals: Blood versus Bloodless And where they lived: Land, Air or Water

  8. According to Aristotle……. A bird, bat and butterfly are all in the same group

  9. Great Chain of Being “Scala Naturae” Aristotle's view of life was hierarchical; creatures could be grouped in order from lowest to highest, with the human species being the highest.

  10. Exploration Era Exploration era allowed many new specimens to be discovered

  11. Many new plants and animals were brought back to Europe from Asia, Africa, and Americas Had to classify the new organisms and name them; In naming, taxonomist used Latin descriptive words. Names were changing constantly and ended up being very long

  12. What was the scientific name for a Honey Bee in the Exploration Era? Apis pubescens, thorace, subgriseo, abdomine, fusco, Pedibins, posticisglabis, untrinque, margine, ciliates

  13. Wake-up • How did scientific names get “out of hand” during the Exploration Era? • According to Aristotle, group animals together. For example, in your notes yesterday, a bird, bat and butterfly were together.

  14. Carlos Linnaeus Father of Taxonomy Developed a system for universal system for naming organisms: Binomial Nomenclature

  15. Binomial Nomenclature Each organism is named using two Latin descriptive words: Genus: Group of closely related species Species: Group of interbreeding organisms. Most similar

  16. Rules for Binomial Nomenclature • Capitalize the Genus and the species is lower case • Underline or italicize both genus and species

  17. Organism #1: Droserarotundifolia The scientific name Drosera Rotundifolia is derived from the word “Drosos” which means “Dew or Dewdrops” Rotundfolia means “Round Leaves” What is its common name? Sun Dew Life: Plants Clip 9:34

  18. Organism #2: Mantis religiosa The scientific name Mantodea comes from a word meaning “Prophet”. It was named this is 1838 by Herman Burmeister. Religiosa means “religious” What is its common name? Praying Mantis

  19. Organism #3: Hippocampus abdominalis What is its common name? “Hippocampus” means horse and “abdominalis” means abdominal. Pot-Bellied Seahorse Video Link #2

  20. Seven Levels of Taxonomic Organization Remember this sentence to help: King Phillip Came Over From Germany Singing

  21. Six Kingdoms of Life

  22. Six Kingdoms of Life Kingdom: Archaebacteria Prokaryotic Unicellular Autotroph/Heterotroph

  23. Example: Thermophiles “Heating-Loving Bacteria

  24. Six Kingdoms of Life Kingdom: Eubacteria Prokaryotic Unicellular Autotroph/Heterotroph

  25. Example: Escherichia coli aka E. coli

  26. Six Kingdoms of Life Kingdom: Protista Eukaryotic Unicellular/Multicellular Autotroph/Heterotroph

  27. Example: Amoeba proteus aka Amoeba

  28. Six Kingdoms of Life Kingdom: Fungi Eukaryotic Unicellular/Multicellular Autotroph/Heterotroph

  29. Example: Amanita muscaria aka Fly Agaric

  30. Six Kingdoms of Life Kingdom: Plants Eukaryotic Multicellular Autotroph

  31. Example: Passiflora incarnata aka Passion Flower

  32. Six Kingdoms of Life Kingdom: Animals Eukaryotic Multicellular Heterotroph

  33. Wake-up • An organisms genus is acer and its species is rubrum. Write this correctly using binomial nomenclature. • List the seven levels of taxonomic organization from most specific to broades.
