Presentation Transcript

  1. CLASSIFICATIONPrior Knowledge • What is a species? • Why are dogs and cats in different species? • Group Activity: paper and pencil • Go to your lab group. • Take off one of your shoes. • Group shoes according to characteristics. ex. athletic, dress

  2. CLASSIFICATION SHOES Casual Dress Athletic Every shoe should be described individually with the person’s name it belongs to.

  3. SHOE CLASSIFICATION • How did you first classify the shoes? • As the groups got bigger, did the divisions change? • What are some other things that are categorized or organized into classes or groups? ex. grocery stores

  4. How Living Things Are Classified START VIDEO (20 min.)

  5. Naming Organisms Why do we need to name organisms? What is the name of this organism? Why do scientist not want to use common names?

  6. The common name of many animals can be misleading. Ceylon frogmouth (Batrachostomus moniliger) is a bird. Killer whales (Orcinus orca )are not whales, but dolphins.

  7. Flying fish (Parezocoetus mesogaster) do not fly, but glide. Galliwasp (Diploglassus lessorae) is not a wasp but a lizard.

  8. Classifying Living Things NOTES: Why do scientist not use common names? Confusing – more than one common name Misleading – starfish is not a fish Why use a scientific name? There is only one scientific name Felis concolor

  9. Read pg. 300 - 304 Scientific Name What language is used for the scientific naming? Latinex. "E Pluribus Unum“ = “one out of many or of many, one” Since 1873, the law requires that this motto appear on one side of every United States coin that is minted. What are the 2 parts of the scientific name? Genus (Latin for group)species general description exact kind organisms share a major only 1 kind of organism characteristic within a genus

  10. Species name = describes the appearance or distribution of an organism. Taxonomy: Science of the naming and classifying organisms.

  11. Recognizing Relationships Tell me something about each of these organisms. giant saguaro cactus fragrant water lily domestic dog common California mouse three color pansy Carnegiea gigantea Nymphaea odorata Canis familiaris Peromyscus californicus Viola tricolor

  12. Genus + speciesnames should be used when referring to an organism.Species name alone is not enough. Drosophila melanogaster is a fruit fly. Thamnophis melanogaster is a garter snake.

  13. Read pg. 301 What is the correct way to write the scientific name? drosophila melanogaster Drosophila melanogaster Drosophilamelanogaster D. melanogaster * Always capitalize the Genus and not the species. Why are scientific names in Latin? • The language does not change. • It’s tradition. Universal • Don’t have to rename millions of species.

  14. Carolus Linnaeus (1707‑1778), a Swedish botanist whose original name was Carl von Linne. He improved the system of naming plants and animals by a two‑word name to identify the genus and species. “binomial nomenclature”

  15. Matter of Fact:How many species are there? No one really knows how many species exist. Estimates of the total number of species vary from 3 - 30 million to 10 – 100 million, depending on the source. Taxonomists estimate that only 1.5 to 1.8 million species have been identified, but there are no central archives. Sea creatures found after 2005 Tsunami hit.

  16. Worksheet: Writing the Scientific Names of Animals Worksheet and Key

  17. Read pg. 302 – Classifying Organisms physical similaritiesgenetic similaritiesbiochemicalsimilaritiesbehavioral similarities Today taxonomist classify organisms based on: http://nationalzoo.si.edu/Animals/GiantPandas/PandasForKids/classification/classification.htm 7 Classification Groups Kingdom - Phylum - Class -Order -Family -Genus –Species - continent country state county city street house

  18. To help you remember the seven classification groups in order, remember this sentence: Kingdom Phylum Class Order Family Genus Species King Phillip Cried Out For Good Soup

  19. Notice how 1 Kingdom will have many phyla. A phylum will have many classes… One Kingdom will have 1000’s of species in it.

  20. From the chart below, fill in the missing classifications.

  21. Plantae Mammalia Primata Canidae Felidae Homo Panthera sapiens Homo sapien

  22. Read pg. 305 - SPECIES What is the definition of a biological species? A group of natural populations that are interbreeding or that could interbreed, and that are reproductively isolated from other such groups. Hybrids – result of interbreeding by individuals of different species – usuallyinfertile. * Usually artificially brought about. Bengal cat = domesticated cat + Asian Leopard cat mare + male donkey = mule

  23. Zebroid female Liger = lion + tiger male Wolfdog = German shepherd + Wolf
