What evidence is there to support this? 2. What is the Endosymbiotic Theory? 3. What evidence suggests that mitochondria and chloroplasts were once primitive bacterial cells and therefore support the theory of endosymbiosis? 4. How can mitochondrial DNA (mtDNA) help scientists determine evolutionary history? 5. What kind of 'extreme' environment can archaeabacteria survive in? How may this provide clues to the origin of life? 3. Darwin's Natural Selection worksheet (need paper copy) 4. Watch video on Darwin's Finches www.hhmi.org/biointeractive/origin-species-beak-finch Answer the following questions: 1. How did available food sources “select for” beak sizes and shapes? 2. What determined available food sources? 3. How does this case study support Darwin’s Theory of Evolution by Natural Selection? 4. How does this illustrate speciation? What type of speciation? 5. Read the "Mystery of the Flightless Bird" article and answer the following questions: 1. How was Percy Lowe's theory that the bird colonized the island on foot disputed? So, how did the bird get on the island? 2. How has natural selection led to the bird not being able to fly? What type of natural selection does this represent? 3.
