  1. The “Theory” of Evolution • Today’s Goal • Assess prior understanding and misconceptions about evolution. • Discuss our views on evolution. • Homework Evaluating Evidence Worksheet • Warm-upRead through the article on the “theory” of evolution. (front desk) Then, in your journal, write a reflection explaining your opinion. In your response, be sure to address the following: • 1) What does evolution mean to you? • 2) Do you accept the theory as scientific fact? Why or why not?

  2. The “Theory” of Evolution Discuss at your table: Is the Theory of Evolution proven or unproven? Why don’t schools teach alternatives to evolution? Why is it still called a “theory” and not a “fact” or “law” of evolution?

  3. The “Theory” of Evolution Is the Theory of Evolution proven or unproven? How do we go about proving something scientifically?

  4. Scientific Prove-O-Meter How to “prove” something ? proven unproven

  5. Scientific Prove-O-Meter How to “prove” something proven unproven

  6. Scientific Prove-O-Meter How to “prove” something ? proven unproven

  7. Scientific Prove-O-Meter How to “prove” something proven unproven

  8. Scientific Prove-O-Meter How to “prove” something proven unproven

  9. Scientific Prove-O-Meter How to “prove” something proven unproven

  10. Scientific Prove-O-Meter How to “prove” something proven unproven

  11. Scientific Prove-O-Meter How to “prove” something proven unproven

  12. Scientific Prove-O-Meter How to “prove” something proven unproven

  13. Scientific Prove-O-Meter How to “prove” something proven unproven Is it 100% proven?

  14. Scientific Prove-O-Meter How to disprove something ? proven unproven

  15. Scientific Prove-O-Meter How to disprove something proven unproven

  16. Scientific Prove-O-Meter Where is the theory of evolution on this scale? ? proven unproven

  17. The “Theory” of Evolution Is the Theory of Evolution proven or unproven? Why don’t schools teach alternatives to evolution? Why is it still called a “theory” and not a “fact” or “law” of evolution?

  18. Can we figure out scientifically if something is true?

  19. The Realm of Science Proposition: All people born between November 22 and December 22 have certain personality traits in common with each other. TRUE/FALSE? Can all questions be tested this way? Is this a testable hypothesis? • How much evidence is there that the proposition is true? • Does anecdotal evidence count? Sagittarius

  20. The “E” Word It all comes down to… If you can’t observe it, measure it, test it and gather evidence, then... it’s not science. EVIDENCE

  21. What is a Theory? Please write this down in your science journal: Scientific theory  • An explanation of a complex concept that explains how the processes happen. • Composed of many individual proven hypotheses. • Explains all the available evidence. • Much more certain than a hypothesis or fact. Will a theory eventually become a law if it is “proven”?

  22. Other Scientific Theories Cell Theory Theory of Relativity Germ Theory of Disease Gravitational Theory Atomic Theory Theory of Plate Tectonics

  23. What sorts of things does the Theory of Plate Tectonics help explain?

  24. True/False: Evolutionary Theory says that humans evolved from monkeys. How old is the human species? How long ago did apes and humans separate from a common ancestor? How long has there been life on Earth? How old is the Earth? How old is the universe?

  25. True or False? Evolutionary theory teaches that humans evolved from monkeys

  26. FALSE Humans, monkeys, and modern apes had a common ancestor… Although we would probably call it ape-like. • How do we know?

  27. How old is the human species?

  28. The first Homo sapiens appeared about 100,000 to 200,000 years ago • How do we know?

  29. When did the separation of man and ape from a common unnamed ancestor occur?

  30. Between 5 and 10 million years ago • How do we know?

  31. How long has there been life on Earth?

  32. The earliest, simplest organisms originated 3.5 to 4 billion years ago. • How do we know?

  33. How old is the Earth?

  34. 4.6 billion years old • How do we know?

  35. How old is the universe?

  36. 13.8 billion years old • How do we know?

  37. How do we know about evolution? • Is there directly observable evidence?

  38. Genetic heredity • Fossils • Vestigial structures • DNA • Environmental adaptations

  39. What biological class do humans belong to? • Mammalia • What other animals are we related to? • What does it mean that we are “related” to dogs, pigs, elephants, giraffes, and dolphins? • Are we “related” to an earthworm? • Are we “related” to a banana?

  40. Geologic Time Vocab Please define the following terms using the Geology books at your tables. • Uniformitarianism • Paleontology • Relative dating • Superposition • Geologic column • Unconformity • Absolute dating • Radiometric Dating • Half-life • All terms are found in chapter 3. • Define in your own terms.

  41. Evolution Intro Activity Date: _______ Please take out your science journal and set up a new page like this: Evolution Intro Activity 1 2 3 4 5 6 My question: Answers to my question: 1) 2) 3) 4) 5) 6) Result:

  42. Evolution Intro Activity • Answer all six questions, and check them off as you go. Date: _______ Evolution Intro Activity 1 2 3 4 5 6 • 2) Write down 6 of your peers’ responses to your own question. My question: Answers to my question: 1) 2) 3) 4) 5) 6) • 3) At the end, you will look and see what question you have. Record it here. • Average the results for your question. Result:

  43. Remember, you are answering other students’ questions, but you’re only recording their answers for your question. Do not look at your own question until everyone is seated and you are told to flip your sign over! GO!

  44. STOP!

  45. Results Flip over your sign, and record your question. Calculate the average of the answers (drop any answers that are WAY off). If True/False, just record which answer was more common.

  46. True/False: Evolutionary Theory says that humans evolved from monkeys. How old is the human species? How long ago did apes and humans separate from a common ancestor? How long has there been life on Earth? How old is the Earth? How old is the universe?
