      • family
      • genus
      • species
        • organisms of the same species...
          • have more characteristic's in common than they do with organisms of a different species
          • can interbreed to produce fertile offspring
        • organisms that produce fertile offspring
    • variation
      • adaptation
        • adaptations have come about through variation through 1000's of generations
      • cold climates
        • the polar bear
          • a white appearance to camouflage from prey in snow and ice
          • thick layers of fat and fur for insulation against the cold
          • small surface area to volume ratio to minimize heat loss
          • a greasy coat which sheds water after swimming
        • the snowshoe hair
          • white fur in winter and reddish brown fur in the summer
            • camouflaged from preditors
      • some of the features in organisms show continuous variation, some features show discontinuous variation.
      • continuous variation
