  • In your EcoLog answer the following questions:
    • Who is Charles Darwin?
    • How is he related to evolution?
darwin and evolution
Darwin and Evolution
  • Darwin
    • natural selection
      • the unequal survival and reproduction that results from the presence or absence of particular traits
    • evolution
      • a change in the genetic characteristics of a population from one generation to the next
evolution by natural selection
Evolution by Natural Selection
  • 1) Overproduction = Organisms produce more offspring than can survive

In your EcoLog, compare/contrast survival of the fittest and natural selection

evolution by artificial selection
Evolution by Artificial Selection
  • Artificial Selection
    • the selective breeding of organisms by humans for specific characteristics
    • EX: fruits, grain, and vegetables we eat

dog breeds

evolution by resistance1
Evolution by Resistance
  • Pesticide Resistance
    • How do pests develop a resistance to pesticides?
closure
CLOSURE
  • Explain what an adaptation is, and provide three examples
  • Explain the process of evolution by natural selection
  • Describe one way in which artificial selection can benefit humans
  • Explain how a population of insects could become resistant to a pesticide
