  21. Major division of phylum consisting of closely related orders
  22. Major division of kingdom consisting of closely related classes.
  23. Major division of domain consisting of closely related phyla
  24. Major division of life consisting of closely related kingdoms.

    b. fewer
    characteristics in common
    b. fewer
  27. How many living species are there in the genus Homo?

  30. primates belong to what class?
  31. the class Mammaila, birds, reptiles, fish, and amphibians belong to what phylum?
  32. The chaorates and all other animal forms belong to what kingdom?
  33. animals, plants and fungi belong to what domain?
  34. three prefixes used to create additional levels
    • super-
    • sub-
    • infra-
  35. additional taxon that groups genera and divides subfamly
  36. On what basis are species classified into higher taxonomic levels?
    evolutionary relationships

  38. if several genera are related to each other they have a...
    common ancestor
  39. The evolutionary history of a population or taxon.
  40. Similarities due to inheritance from a common ancestor.
    homologies (homologous features)
  41. what is a flipper an eleboration of?
    the basic structure of the forelimb of a four-footed land vertebrate
  42. Referring to similarities that are not homologous. It can arise from parallelism, convergence, analogy, and chance.

    • Marsupial
    • placental mammals
  45. Marsupials must have diverged from the mammalian line before or after the evolution of the placenta?
  46. Homoplastic similarities found related species that did not exist in the common ancestor; however, the common ancestor provided initial commonalities that gave direction to the evolution of the similarities.
  47. Old and New world monkeys exemplify homoplastic similarities arising from what process?
  48. Similarities between the Tasmanian wolf and the grey wolf result from...
    convergent evolution
  49. Structures that are superficially similar and serve similar functions but have no common evolutionary relationship.
