Charles Darwin Alfred Wallace both Darwin and Wallac none of the other answers to this question Question 2 Which of the following is an example of convergent evolution? two populations of birds that evolved from a single species two plant populations that evolved from a single plant species two small animal populations that developed in different continents but share long floppy ears in common two individuals that built their musculature at the same gym so they could compete against each other Question 3 Which of the folloiwng is NOT a key principle of natural selection? Characteristics of organisms are inherited More offspring are produced than are able to survive Offspring vary among each other in regard to their characteristics All offspring will survive if they help each other out during rough times Question 4 Which of the following is NOT one of the types of natural selection? stabilizing selection disruptive selection directional selection sexual selection Question 5 With natural selection, generally, organisms with current favorable traits have a better chance at survival. True False Question 6 With natural selection, generally, the longer an organism lives, the more reproductive opportunities it will have. True False Question 7 With natural selection, generally, more organisms will exist with the same favorable trait than the previous generation True False Question 8 Match the type of natural selection with the correct example. __3__ only giraffes with very long necks survive __2__ tall giraffes and short giraffes are rare but average height giraffes are common __1__ tall giraffes and short giraffes are prominant but average height giraffes are rare 1. disruptive selection 2. stabilizing selection 3. directional selection Question 9 All mutations are harmful and result in death of the organism. True False Question 10 A typhoon in the southern tip of Japan is more likely to result in which type of evolutionary influence among a certain insect that pollinats flowering trees. natural selection genetic drift neither of the other answers for this question both of the other answers for this question
