Resumo de Recurso

Adaptation,Natural Selection and evolution of species
  1. Mutation
    1. Random change in genetic material
      1. occur at random , are spontaneous
        1. increased due to radiation and chemical exposure
        2. Variation
          1. difference that exists between members of the same species
            1. How a population evolves over a time due to change in enviromental changes
            2. Natural Selection
              1. usually occurs when more offspring than the enviroment can substain are produced
                1. Only the best adapted individuals are produced will survive to reproduce
                  1. Will pass on genetic information to offspring
                2. Speciation
                  1. occurs when a population becomes isolated
                    1. Natural selection follows a different path due to different conditions within the enviroment
