    It only works with living animals
  32. Things look sufficiently different, so they are classified as a different species.
    consistency is the key.
    Morphological Species Concept
  33. It is tough to tell if geographic variance of different species. Also, genetic tests may disagree.
    Problems with Morphological Species Concept
  34. Looking at the DNA, the genetic code
