Question 1

Whether you “believe” in evolution or not, why is it important to be knowledgeable about Darwin’s theory? How might genetics and evolution apply to our modern society when we consider the differences between people? Should we stratify people based on intelligence or other specific qualities? Have you observed traits in your parents that you do not like and see them in yourself? (You do not have to be specific about personal issues but can write about issues in a general sense.)

Your journal entry must be at least 200 words in length. No references or citations are necessary.

Question 2

Pine trees that are too tall or too short do not do as well as pine trees that are average in height. The short trees do not get as much light as tall or average trees. The tall trees are more likely to break off in storms. Tell how this is an example of stabilizing selection. Be sure to define stabilizing selection in your answer.

Your response must be at least 75 words in length.

Question 3

There is a moth in England called the peppered moth. Before Britain’s industrial revolution, these moths were usually salt and pepper colored. Because of their coloring, they blended in well with the tree trunks on which they tended to rest. The coloring helped them hide from the birds that ate them. During the British industrial revolution, industry expelled a lot of soot from the burning of coal into the environment. This soot darkened the tree trunks, and it was noted that black-colored moths were becoming predominant. The idea is that with soot in the environment, black-colored moths fared better than light-colored moths. There is some debate as to whether this is actually the case or not, but for the sake of this question, let’s assume it is.

In your own words, explain the concepts from the four observations discussed in 12.2 using the moth as an example. In other words, how does the moth illustrate the first observation, the second observation, etc.?

Your response must be at least 200 words in length.

Question 4

Have you ever driven through a rural area and thought, “There is nothing out here”? Does that make you think that there is plenty of land “out there” for everyone? Was the area you were driving through actually fallow, or might it have been used for some purpose, such as growing trees for pulpwood or lumber? Did the rural area reassure you that your family would have enough space to live and grow, or are you still concerned? What kinds of things can one do to conserve the land?

Your journal entry must be at least 200 words in length. No references or citations are necessary.
