Darwin's Dangerous Idea Video Chapter 1. Prologue (5:11) Introduction to the show and to Darwin Darwin's voyage on the Beagle Natural selection: a revolutionary and dangerous idea Chapter 2. Common Ancestry (14:47)Darwin's return to England The puzzle of the Galapagos finches Darwin's initial ideas about adaptation and the development of new species Darwin's relationships with his brother and with fellow naturalists Chapter 3. Ecuador and the Tree of Life (12:55)Darwin's theory of a single tree of life and current biological research In Ecuador, biologists explore how adaptations to new environments can create new species Comparisons of rainforest and mountain hummingbirds What Darwin learned from the Galapagos finches Using DNA to determine when species diverged Chapter 4. Natural Selection (9:04)Darwin's marriage and the development of his thinking Darwin's relationships with his brother, scientific peers, and future wife Darwin considers Malthus theories of human growth and struggle Does survival of the fittest apply to all species? Even humans? Chapter 5. Mutation and HIV (12:59)A modern definition of natural selection, and HIV as an example of evolution in action Natural selection explained in detail How traits are passed along to offspring Two personal stories about HIV explore how natural selection produces drug-resistant viruses How scientists use their understanding of natural selection to combat HIV Notes Discussion Questions: Movie Darwin’s Dangerous Idea http://www.pbs.org/wgbh/evolution/darwin/index.html 1. Why are finches important to Darwin’s idea? (22 minutes) 2. What does the shape and color of the mantis tell us? 3. What can we learn from hummingbirds? How do they provide evidence for Darwin’s Dangerous Idea? How do new species arise? How does DNA help explain the divergence in hummingbirds? 4. Darwin talks to Emma (30 minutes); Explain how Darwin and Emma’s views differ with respect to dogs? What happens when nature chooses? (think puppy?) What was Emma’s challenge to Darwin? Why is this important? (35 min) 5. What scene in the video is related to Malthus predictions? a. Why are we not overrun by insects? b. Why might the ugly duckling win in the end? 6. How does the coloration of beetles help explain Darwin’s Dangerous Idea? What is the beginning of success? Who survives? And why do they? 7. How does our understanding of HIV treatment support Darwin’s Dangerous Idea? (43 MIN) Can we see Natural Selection in our time? Why don’t drugs stop HIV? Like they might with other illnesses? How does HIV evolve? 8. What do the dissection of the chimp and the bones show to Owen? To Darwin? 9. What do Huxley and Owen argue about? (86 min)
