Name: Date: Brain Pop: Natural Selection 5. In the movie, the __________ colored fish mutated. The red was a (positive / negative) trait and the grey was a (positive / negative ) trait. Why: 1. What did Charles Darwin notice about the birds that lived on the Galapagos Islands? What did he eventually conclude from his observations? 6. _____ is an example of a “favorable” (good) mutation. a. A mutation that makes a rabbit run faster b. A mutation that changes the rabbit’s fur orange c. A mutation that gives the rabbit a third ear. 2. Two animals belong to the same species if _____. a. they live in the same environment. b. they look alike. c. they can reproduce. 7. In the expression “survival of the fittest,” the word “fittest” means _____. a. the best adapted organisms b. the biggest organisms c. the smartest organisms 3. _____ is an example of an environmental pressure. a. Air pressure b. A lake that is slowly running out of water. c. Fighting between males of the same species. 8. True or False: If a mutations is advantageous, then it will more likely pass to the offspring. Why? 4. IF all life on Earth is related, (if we look back far enough) THEN _____. a. Many different species lived at the same time. b. all living things evolved from a few simple life forms. c. Very few species have become extinct over time. 9. Life on Earth is like a tree because _____. a. all life needs water to survive. b. all of the different branches are connected. c. we are all part of nature. 10. What is a “common ancestor”?
