13. Evolution: Change Over Time

14. In order for evolution to happen, you need…. VSIT Variation Selection Inheritance Time

15. Variation S I T Difference between individuals Stands for… Means…

16. VSelection I T Individuals with “good” traits will survive and reproduce more Stands for… Means…

17. V SInheritance T Genes are passed from parent to child Stands for… Means…

18. V S ITime MANY generations Stands for… Means…

19. What does selection mean?

20. Vocabulary an inherited trait that increases an organisms chance of survival and reproduction the ability of an organism to survive and reproduce in its environment Adaptation Fitness

21. Differences among individuals When there is variation, some individuals will have better fitness (good genes) Variation

22. Natural Selection Natural Selection: Organisms best suited to their environment as a result of good genes survive and reproduce. Natural Selection = reproduction (and survival) of the fittest

23. Natural Selection is WHY Darwin’s finches matched their environment Natural Selection

24. Big beak Survives longer Reproduces more Passes on more genes Big beaks become more common This process is an example of NATURAL SELECTION! EVOLUTION BY NATURAL SELECTION In an environment with BIG SEEDS… = adaptation

25. Small beak Survives longer Reproduces more Passes on more genes Small beaks become more common This process is an example of NATURAL SELECTION! EVOLUTION BY NATURAL SELECTION In an environment with SMALL SEEDS… = adaptation

26. Natural Selection Needs... VSIT Variation Selection Inheritance Time

27. Camouflag e Survives longer Reproduces more Passes on more genes Camouflage becomes more common This process is an example of NATURAL SELECTION! EVOLUTION BY NATURAL SELECTION In an environment with PREDATORS = adaptation

28. Adaptations

29. Adaptation An inherited trait that increases an organism’s chance of survival and reproduction Organisms adapt to their environment

30. Adaptations in animals Mimicry Camouflage Adaptations in plants Coevolution Outline

31. Mimicry Mimicry: an adaptation that allows one species to look like a more dangerous species Predators are less likely to attack a mimic

32. Mimicry Mimicry Coral Snake vs Scarlet King Snake

33. Camouflage Camouflage: an adaptation that allows a species to blend in with its surroundings so predators cannot see it Predators are less likely to find a camouflaged animal

34. Camouflage

35. Camouflage

37. Plant Adaptations Plant Structure Leaves adapt to a plants environment Example 1: plants that live on the rainforest floor (so get little light) have broad, flat leaves to capture as much light as possible

38. Plant Adaptations Plant Structure Leaves adapt to a plants environment Example 2: cactus that live in the desert (so get little water) have spines for leaves to keep from losing water

39. Plant Adaptations Plant Feeding Carnivorous plants have adaptations that let them eat animals Example: pitcher plants

40. Coevolution Coevolution: species that rely on each other adapt to each other

41. Example: the cardinal flower and the hummingbird The tube in the cardinal flower is the same length as the beak of they hummingbird. They are adapted to each other! Coevolution

42. Exit Ticket What is natural selection? What is an adaptation? What is the difference between camouflage and mimicry? Provide an example of of each (camouflage and mimicry). What is coevolution? Provide and example of coevolution.
