  • Evolution by natural selection
    • Mutations
      • change in a gene or a chromosome
      • rare and a random change in the genetic material
      • many have no effect but it can adapt to the phenotype rarely
      • if adapted it can be an advantage- better suited in a particular environment
    • Survival of fittest and evolution
      • survival of the fittest
        • individuals with better characteristic will be most suited
        • individual organisms within a particular species show a range of phenotype and genetic variation
        • alleles that survive will be passed to the next generation
    • Natural selection
      • is the process where organisms that are better adapted to an environment will survive and reproduce
