Presentation Transcript

  1. Thursday, April 4th Warm-Up • Put the biologic events in chronological order and number them #1-5. • Invertebrates thrive • Dinosaurs dominate • Amphibians evolve • Bacteria appear • Birds and mammals evolve Agenda • Intro to Evolution Notes • Moth Activity Homework • FINISH Part 2 Vocab – Due TOMORROW!

  2. The Theory of Evolution

  3. What is a Species? • Species – A group of organisms that are able to produce offspring that are healthy and capable of reproducing together.

  4. What is Evolution? • Evolution – A change in the inherited traits of a species from one generation to the next. • Every organism has unique DNA, which makes some organisms better suited to environmental changes than others. • Organisms that cannot adapt to their environment will NOT survive.

  5. Extinction • If all the organisms within a species are unable to adapt to an environmental change, the species will become extinct. • Extinction – when all of the organisms within a species die.

  6. Scientists who studied Evolution • Gregor Mendel • “Father of Genetics” • Studied how traits are passed down from one generation to the next in pea plants. • Charles Darwin • Studied how organisms within a species change when they move to new environments.

  7. “Survival of the Fittest” • Natural Selection- Animals develop traits over time in order for the species to survive.

  8. Adaptations • Adaptations – a beneficial trait that helps an organism survive in its environment. • Examples: • Camouflage • Mimicry • Hibernation

  9. Camouflage • When an animals physical appearance blends in with its environment.

  10. Mimicry • When an animal mimics or imitates another animal in order to survive. • The milk snake mimics the colors of the poisonous coral snake.

  11. Moth Activity • What adaptation would a moth use to avoid predators if it lived in this classroom?

  12. Moth Activity • What adaptation would a moth use to avoid predators if it lived in this classroom? Camouflage

  13. Moth Activity • Design and color a moth that would blend in somewhere in the classroom. • Write your name on the back of the moth. • You CANNOT hide them INSIDE or UNDER something… they must be visible, but blend in with the background. • Tomorrow, we will tape them up and the next class will “hunt” for the moths. • The moths that are NOT found are the “fittest” and will receive a Bonus Buck!

  14. Friday, April 5th Warm-Up • Turn in Vocab during warm-up time. Choose ONE question: • What does Natural Selection mean? • Name one adaptation and describe how it helps an organism survive in its environment . Agenda • Tape Moths up • Moth Hunt • Walking with Dinosaurs
