  1. Webquest: Scientific Evidence for Evolution Name: _______________ Score _____/7

  2. Directions • As you proceed through this webquest, record all work on the worksheet • Visit each bay for directions on the six individual activities • Do not forget to complete the definition of evolution

  3. Like all good scientific theories, evolution must have scientific evidence to support it This evidence falls into 8 or more important categories: 1. Fossil Record 2. Homologous structures 3. Analogous structures 4. Vestigial structures 5. Geographical distribution 6. Embryological studies 7. Genetic & biochemical comparisons 8. Resistance to antibiotics & pesticides

  4. Define the theory of evolution Go to the following site for information and then define the theory of evolution in your own words: Interactive Site: http://www.pbs.org/wgbh/nova/id/predictions.html Printable version: http://www.pbs.org/wgbh/nova/id/pred-nf.html

  5. 1: Fossil Record A. Why are fossils considered part of the scientific data that supports Evolution? read the text on this page: http://www.pbs.org/wgbh/evolution/library/04/3/l_043_01.html Visit this website to learn about transitional forms (Launch Interactive). http://www.pbs.org/wgbh/nova/id/transitional.html

  6. 1: Fossil Record (cont.) B. What evidence did scientists use to determine the fossil they found was that of a whale? C. How do scientists use fossils to learn when whale ancestors were living on earth? Watch the 10 minute video (Video # 3: “How Do We Know Evolution Happens”) answer the Questions above in your notebook: https://www.youtube.com/watch?v=ewtw_nZUIDQ&list=PLvFQyVl48bpzzmyVQLpDsWydyBqi_Zc-J

  7. 2: Homologous structures A. Color-code the homologous structural parts on the sheet "Adaptive Radiation: Mammalian Forelimbs." B. What are homologous structures? C. Why are these considered evidence for Adaptive Radiation or Divergent Evolution? http://www.pbs.org/wgbh/evolution/darwin/origin/index.html http://evolution.berkeley.edu/evolibrary/article/similarity_hs_01

  8. 3: Analogous structures A. What are analogous structures? B. How is this evidence for Convergent Evolution? http://evolution.berkeley.edu/evolibrary/article/similarity_hs_01

  9. 4: Vestigial structures A. What are vestigial structures? • Give an example of a vestigial structure in humans. • Give an example of a vestigial structure in some other organism. B. Why are vestigial structures considered evidence for evolution? http://www.livescience.com/animals/top10_vestigial_organs.html

  10. 5: Geographical Distribution A. What did Wallace and Wegener discover? • How does their evidence support the theory of evolution? http://evolution.berkeley.edu/evolibrary/article/0_0_0/history_16

  11. 6: Embryology A. What is embryology? • Compare the stages of development illustrated on the sheet "Comparative Embryology" and in the diagrams in the Glencoe textbook (Page 433, Figure 18.11) • Create a branching diagram (like a family tree) which shows the degree of relationship between the animals listedin these pictures (Pg. 433, fig. 18.11) (6 total). Relationships are based on the similarity of their embryos. B. How do embryological studies provide evidence for evolution?

  12. 7. Genetics & Natural Selection • Describe natural selection and how it relates to the humming bird: Click on the link below: • https://www.youtube.com/watch?v=xkwRTIKXaxg&list=PLvFQyVl48bpzzmyVQLpDsWydyBqi_Zc-J&index=4 • Or • http://science.howstuffworks.com/life/evolution/natural-selection.htm

  13. 8. Resistance to antibiotics • A. WHAT IS ANTIBIOTIC RESISTANCE? • B. HOW DID IT EVOLVE? • C. TAKE THE ANTIBIOTIC QUIZ. http://www.cdc.gov/getsmart/community/about/antibiotic-resistance-faqs.html

  14. More Connections: Lucy A. Where was Lucy found? B. How old is she? C. What does Lucy tell us about evolution? http://www.bbc.com/earth/story/20141127-lucy-fossil-revealed-our-origins

  15. More Connections: Hydrothermal Vents • How are Hydrothermal vent ecosystems similar to what it may have been like on the Early Earth? http://www.divediscover.whoi.edu/expedition1/
