Lab 8 Evolution Lab Write Up A. Galapagos Finch Evolution — HHMI BioInteractive Video https://www.youtube.com/watch?v=mcM23M-CCog Answer the following questions after watching the film “Origin of Species: The Beak of the Finch”. 1. What are the two different theories as to why there are 13 different species of finches on the islands? 2. Which of these two theories is the correct one? What type of evidence proves that this theory is correct? 3. What is the definition of a “species” that is used in the film? 4. What are some different types of food eaten by finches on the islands? 5. What type of seed became scarce during the drought? What type of seed was abundant? 6. What is one way that finches identify others of the same species to mate with? B. The Relationship of Beak Depth and Rainfall Part I. Gray= red= 1976 Beak length Black= 1977 Beak length 6A. What is the most common beak size of finches in 1976? _______ 6B. Approximately how many birds had the most common beak size in 1976?_______ 6C. Approximately how many birds had this beak size in 1977? ________ 7A. What is the most common beak size of finches in 1977? _______ 7B.Approximately how many birds had the most common beak size in 1977? ________ 7C. Approximately how many birds had this beak size in 1976?__________ 8. Using your answers for questions 6-7, what are two observations you can make from the graph in terms of …. (1) number of ground finches and (2) their beak characteristics in the years 1976-1977. C. The Relationship of Beak Depth and Rainfall Part II. The following table relates to Peter and Rosemary Grant’s data collected on Daphne Major in the Galapagos Islands as discussed in the video above. Use the above information to explain why average phenotypic beak size oscillates overtime. 9. Why should you see an increase in beak size during periods of drought? 10. Why should you see a decrease in average beak size during wet years? *Continued on the next page* D. Bird Beak Adaptations Examine the pictures of the different bird below and label the images below with their corresponding letter. Which of the birds would be best adapted for each of the below feeding strategies? Northern House Great Horned Ruddy Cormorant Parrot Sand Piper Flicker Finch Owl Duck Bird Letter Feeding Strategy ________ consuming hard to crush large seeds ________ catching slippery fish ________ shoveling through wet sandy soil for invertebrates ________ catching insects hiding in the bark of trees ________ tearing flesh from a rodent ________ consuming small soft seeds ________ probing for food sources in the mud
