In the course of human evolution, we can see in the fossil record a tendency towards increasingly large brains as this feature likely served as an adaptive advantage. In terms of natural selection this is known as a. Random Selection b. Stabalizing Selection c. Directional Selection d. Disruptive Selection

17.According to the excerpt from the Descent of Man in Sources of Making of the West… Charles Darwin asserts that observed differences between human races are evidence of multiple places of origin for humanity. Darwin acknowledges that his conclusions “will be denounced by some as highly irreligious” but he dismisses this as a valid argument against his explanation of human origins. Darwin asserts that “the assumed instinctive belief in God” is a valid argument for the existence of such a God. Darwin deliberately insults the Christians in his reading audience to gain traction for his arguments.

8. Give an example of a positive effect of selective breeding. (It can be ascertained from the article, our lesson, or the supplemental videos)

9. This theory states that organisms with desirable characteristics may survive while those with weaker traits may not. *   a. Use and Disuse b. Natural Selection c. Need d. Earth’s   10. Which of the following statements best explains the idea of Darwin about Natural Selection? *   a. The abundance of certain species in an area is somehow related to the type of available food around it. b. The abundance of certain species in an area is not related to the type of available food around it. c. Both a & b d. None of the above.

1. Which among the following is NOT a principle of natural selection?  a. The genes produced are a combination of the surviving and less favorable species b. The characteristics of organisms are inherited or passed from parent to offspring. c. Offspring vary among each other about their characteristics, and those variations are inherited d.More offspring are produced than can survive   2. Which of the following information is FALSE about the development of evolutionary thought?  a. In his essay on the Principle of Population, Thomas Malthus predicts that the human population will grow faster than space and food supplies needed to sustain it. b. Charles Darwin set sail on the HMS. Beagle, a voyage that would provide him with evidence that leads to his theory of evolution. c. In the second and final volume of Principles of Geology, Alfred Wallace explained that processes occurring now had shaped Earth's geological features over a long time. d.…

8. In human populations birth survival rates tend to increase towards children born with a more average birth weight. In terms of natural selection this is known as a. Disruptive Selection b. Directional Selection c. Stabalizing Selection d. Random Selection

21. Natural selection results in change overtime by acting on traits that are _________? *       a. heritable.       b. new.       c. mutated.       d. better. 22. Evolution is often described as "the theme that ties together all aspects of biology." This is because the process of evolution ________________________. *       a. explains how organisms become adapted to their environment.       b. explains the diversity of organisms.       c. explains why distantly related organisms sometimes resemble one another.       d. all of the above are appropriate answers.

6. Which of the following statements does NOT describe Darwin's theory of natural selection  A. Members of a population will complete  B. Members of population have heritable variations.  C. Populations tend to reproduce in small numbers.  D. Sa members of a population have adaptive traits.

1. Wood duck is one of the most recognizable birds in the United States. In the late winter season, the males attract the females with their call and colorful markings. The female wood ducks chose their partner based on their attractiveness. They then pair up and begin breeding in the early spring. What mechanism of evolution is described in the given situation? a. natural selection b. genetic drift c. non-random mating d. genetic flow   2. Which of these factors DO NOT produce an adaptive evolutionary change in a given environment?  a. natural selection b. none of them c. mutation d. genetic drift

14. Which of the following statements describe divergent evolution? * A. Two organisms which live in a certain area developed the same characteristics after a while. B. A population of certain organisms went separate ways and developed different structures. C. A and B both describes divergent evolution. D. A and B do not describe divergent evolution.
