31.  Pegasus-In Greek mythology, the winged horse that sprang from the blood of the Gorgon Medusa when she was decapitated by the hero Perseus. He carried Bellerophon in his fight with the chimera, and was later transformed into a constellation.Gorgonchimera  Centaur-In Greek mythology, a creature half human and half horse, wild and lawless. Chiron, the mentor of the hero Heracles and tutor of the god of medicine Asclepius, was an exception. Their home was said to be on Mount Pelion, Thessaly.  Griffin-Mythical monster, the supposed guardian of hidden treasure, with the body, tail, and hind legs of a lion, and the head, forelegs, and wings of an eagle, though in classical times all four legs were those of a lion.  Dragon-Mythical monster, can grow hundreds of feet long, has a snake-like body, four legs, 1-3 reptile like heads, 2 wings, scaled and breathes fire.  Chimera-In Greek mythology, a fire-breathing animal with a lion's head and foreparts, a goat's middle, a dragon's rear, sometimes heads of all 3. Alternately, any apparent hybrid of two or more creatures.  Hydra-In Greek mythology, a huge monster with nine heads, four legs, spiked tail, and scales. If one were cut off, two would grow in its place.

32. Monday TAXONOMY

33. TO DO for today:  Clear off tables and take out a pencil  Check Homework  Section 2 Notes Answer the following in your notes:  What are homologous, analogous, and vestigial structures?  Give an example of each. MONDAY

34. Classification Notes

35. The 3 domains Eukarya Bacteria Archaea

36. Figure 10.1 The Three-Domain System

37. Table 10.1

38. Why do we classify things? Supermarket aisles Libraries Classes Teams/sports Members of a family Roads Cities Money

39. What is classification? Classification: putting things into orderly groups based on similar characteristics Taxonomy: the science of describing, naming, and classifying organisms

40. Early classification Aristotle grouped everything into simple groups such as animals or plants He then grouped animals according to if they had blood or didn’t have blood, and if they had live young or laid eggs, and so on…

41. Binomial Nomenclature Developed by Carolus Linnaeus Swedish Biologist 1700’s Two-name system Genus and species named using Latin or Greek words

42. Rules used to write scientific names Homo sapiens Genus -written first Species- written second The genus is Capitalized; the species is written in lower case Scientific names of organisms are always italicized or underlined Escherichia Coli= E. Coli

43. Modern Taxonomy The Evidence used to classify into taxon groups 1) Embryology 2) Chromosomes / DNA 3) Biochemistry 4) Physiology 5) Evolution 6) Behavior You can’t forget it!

44. The modern system of classification has 8 levels: 1. Domain 2. Kingdom 3. Phylum 4. Class 5. Order 6. Family 7. Genus 8. Species

45. Helpful way to remember the 8 levels Dumb kids playing catch on freeways get squashed Dear King Phillip Came Over For Good Spaghetti Or…use your own… D K P C O F G S

46. Using the Classification System Field guides help identify organisms. -they highlight differences between similar organisms (like trees) Taxonomic Key (Dichotomous Key) -paired statements that describe the physical characteristics of different organisms

47. Taxonomic Key  1a Fruits occur singly................................................. Go to 3  1b Fruits occur in clusters of two or more................ Go to 2  2a Fruits are round................................................... Grapes  2b Fruits are elongate............................................... Bananas  3a Thick skin that separates easily from flesh.........Oranges  3b Thin skin that adheres to flesh.............................. Go to 4  4a More than one seed per fruit............................ Apples  4b One seed per fruit............................................ Go to 5  5a Skin covered with fuzz.................... Peaches  5b Skin smooth, without fuzz........................... Plums What steps would you use to identify an apple?

48. Cladogram questions Using the cladogram, which animals have claws/nails? Which animals have fur/mammary glands? To what is the chimp most closely related to?

49. Ingroup – group studied Outgroup – group not part of ingroup, used to “root” tree

50. Is a hippopotamus more closely related to a pig or to a whale? Be able to defend your answer!

51. HIPPO WHALE Based on physical comparisons (particularly dental structure and number of toes) it was originally thought that hippos were most closely related to pigs but DNA analysis indicates that hippos are more closely related to whales!

52. Evolutionary Link Whales and hippos had a common water-loving ancestor 50 to 60 million years ago that evolved and split into two groups: The cetaceans (whales, dolphins, and porpoises) The pig-like anthracotheres – died out less than 2.5 million years ago, leaving only the hippo as a descendent

53. Cladogram

54. Cladograms are used to… Organize organisms based on evolutionary relationships (phylogeny). In other words… who is related to who and where did we come from…

55. How are cladograms constructed? Organisms are grouped together based on their shared derived characteristics (trait modified from the ancestral trait). What is the ingroup? What is the outgroup?

56. Cladogram construction Given a table of derived characters (traits), create a cladogram

57. Step Two – Convert the Venn Diagram into a Cladogram Vertebrae Shark Two pairs of limbs Bullfrog Mammary Glands Kangaroo Placenta Human

59. Convert the Venn Diagram into a Cladogram Earthworm Trout Lizard Human Vertebrae Legs Hair
