  2. Natural Selection • Natural selection is a process that causes heritable alleles that are helpful for survival and reproduction to become more common, and harmful alleles to become more rare. • This occurs because organisms with “better” alleles pass on more copies of these heritable traits to the next generation

  3. Adaptations • Adaptations are the characteristics that give individuals better chances of surviving and or reproducing.

  4. Car #1 What is this car adapted for?

  5. Car #1 Adapted for s p e e d

  6. Car #1 This Pronghorn Antelope is also adapted for speed. Adapted for s p e e d

  7. Car #2 What is this car adapted for?

  8. Car #2 Adapted for CLIMBING

  9. Car #2 This big horned sheep is also adapted for climbing. Adapted for CLIMBING

  10. Car #3 What is this vehicle adapted for?

  11. Car #3 Adapted for water and land-- amphibious

  12. Car #3 This tiger salamander is also adapted for a life in both land and water. Adapted for water and land-- amphibious

  13. Car #4 What is this vehicle adapted for?

  14. Car #4 Adapted for safety and protection

  15. Car #4 This desert tortoise is also adapted for safety and protection. Adapted for safety and protection

  16. Car #5 What is this vehicle adapted for?

  17. Car #5 Adapted as a generalist. It’s good at a lot of things but not great at any.

  18. This coyote is also a generalist. It is medium speed, ok at climbing… Car #5 Adapted as a generalist (speed, protection, climbing…)

  19. Car #6 Toyota Prius (Hybrid)

  20. Car #6 Toyota Prius (Hybrid) Adapted to use less resources

  21. This kangaroo rat also survives with few resources. Car #6 Toyota Prius (Hybrid) Adapted to use less resources

  22. The Ancestral State • This is a photo of the first car, a Model-T Ford. • All the cars we just looked at evolved from this original

  23. All the cars have a common ancestor but are now adapted for different environments. The Ancestral State Notice how the Toyota Prius evolved from the Toyota Camry. This is a more recent ancestor for the Prius.

  24. A Tale of Intermediate Forms • When looking at a 1909 Model-T Ford and a 2010 Ford Mustang it is hard to see how we got from one to the other– they look so different. ?

  25. A Tale of Intermediate Forms • However, if we look at the history of cars, we get a better picture 1909 1920

  40. Evobot Lesson • Together we will all build an ancestral state. • Then, you will have 30 minutes to develop a Evobot to compete in a specific environment.

  41. Environments • Flats (The fastest evobot has the advantage) • Mountains (The evobot that can climb the steepest hill has the advantage)

  42. Environments • Founder (The evobot that is completed first has an advantage) • Desert (The evobot that uses the least legos or resources gains an advantage) • Reproduction (The best looking evobot and the weirdest looking evobot gain an advantage)
