Natural Selection

  • Differential Repoductive Success is natural selection

  • If you have a higher fitness level, higher survivability

    • Higher fitness pass on genes, lower fitness die

  • Evolution creates new alleials

  • Gene pool is a combination of all genes in population

  • Mutation and reproduction create variety

    • Adaptation is from these two

  • Hardy Weinberg Equilibrium

    • 1848

      • p^2 + 2pq + q^2 = l

      • DD Dd dd

      • q^2 = .98

        • Q = .99

    • 1895

      • q^2 = .05

        • Q = .22

  • Adaptation Process

    • Adapt to environment through natural selection to exploit niches

    • They work their way up the ecosystem

    • Species are created as traits are formed from adaptions to the enviroment
