9. Give an example of how a species will change over time.

11. How will a mutation affect an organism’s chance of survival?

13. Which term refers to the process by which individuals that are better adapted to their environment are more likely to survive and reproduce?

15. How does natural selection lead to evolution? A. Stronger offspring kill weaker members of the species. B. Helpful traits accumulate among surviving members of the species. C. Overproduction provides food for stronger members of the species. D. Environmental changes kill weaker members of the species.

16. B. Helpful traits accumulate among surviving members of the species.

17. New species formed when groups were isolated by the process of _________________________, in which Pangaea split apart.

19. Give an example of how a mutation could be an advantage.

20. Answers will Vary

21. Explain why variations are needed for Natural Selection to occur?

22. Otherwise all individuals would be adapted to their environment and equally likely to survive and reproduce.

23. Which fruit phenotype (physical characteristic) reached the ground most often? Why?

25. Which trait of the Catchecans allows them to be most successful in meeting family food needs? Why?

27. Consider the future of the Swiftus supersonicus. What are you going to do with these birds? They are eating the fruit that could feed more Catchecans. Suggest a method by which the problem could be solved without endangering the species.

29. Using the underlined words explain how variation, adaptation, survival, and reproduction, have played a vital role in the way the Catchecans have changed over the generations. Write the explanation in your notes.

30. There are many variations amongst members of the Catchecan tribe. One adaptation they have developed is fast reflexes. Survival is dependant upon the ability to catch Bebblefruit. Those who feed their family will ensure that their traits will be reproduced in future generations.

31. What would happen to the Catchecans who always fed their last born first?

43. How will humans impact the evolution of man’s best friend, the dog?

45. Name a change or adaptation that may be occurring in the human population on Earth?

47. How will climate change affect the polar bear species?

49. Identify a logical reason as to why this animal exhibits these traits.

51. What characteristic of the human race will ensure its survival in the future?
