  • HW: 1) Complete Peppered Moths

    questions

    2) QUIZ on FRIDAY

    3) TEST on THURSDAY


Do now

DO NOW

  • In your EcoLog answer:

    • What do you think…what does natural selection mean?


Aim and hw1

AIM and HW

  • AIM: How do organisms become so well suited to their environment?

  • HW: 1) Finish article questions

    2) TEST on THURSDAY –

    start studying!


Do now1

DO NOW

  • 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


Evolution by natural selection1

Evolution by Natural Selection

  • 2) The environment is hostile and contains limited resources


Evolution by natural selection2

Evolution by Natural Selection

  • 3) Organisms differ in the traits they have


Evolution by natural selection3

Evolution by Natural Selection

  • 4) Some inherited traits provide organisms with an advantage

  • 5) Each generation contains proportionately more organisms with advantageous traits


Aim and hw2

AIM and HW

  • AIM: Why does evolution matter now?

  • HW: 1) TEST TOMORROW

    (Chapter 4)


Do now2

DO NOW

  • In your EcoLog, discuss the events of the video


Aim and hw3

AIM and HW

  • AIM: How does natural selection impact future generations?

  • HW: 1) TEST TOMORROW

    (Chapter 4 – Sections 1 & 2)


Do now3

DO NOW

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 resistance

Evolution by Resistance


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
