Week 3: Seminar Questions on Darwin reading

 

Each  member of  the  small groups should briefly indicate what they found most striking in the reading;  the group as a whole should ultimately formulate a question for the full seminar discussion.

 

On Origin of Species selection

Q1 Review the mechanisms that Lamarck and Darwin proposed for evolutionary changes in a species. How would they each explain the transformation of, say, an antelope into a giraffe? What mechanism would likely produce faster evolutionary changes?

 

Q2  Suppose that you could choose between a world governed by Lamarckian inheritance of acquired characters or Darwinian natural selection? Which world would you choose to live in? Why?

 

Q3  What strategies did Darwin use to make his theory of evolution by natural selection palatable and persuasive to a highly skeptical audience?

 

On Descent of Man selection

Q4 How do the following three classes of observations provide evidence that humans descended from lower animals: a) homological structures, b) embryological development, c) rudimentary organs? How does Darwin explain the existence of the human appendix, given the fact that it sometimes causes death? How does he explain the existence of male mammary glands and nipples?

 

Q5 In Chapters 1 and 2, Darwin focuses on similarities between humans and other species, both in terms of structure and function and in terms of evolutionary mechanism. Summarize the main points of this argument. What would you add if you were making Darwin’s argument today?

 

Q6  How, if at all, does Darwin employ Herschel’s notion of analogical reasoning or Whewell’s notion of consilience apply to the mechanism of human evolution?

 

Q7 Darwin states that his purpose in Chapter 3 is “to shew that there is no fundamental difference between man and the higher mammals in their mental faculties” (p. 21). In the second part of the chapter, Darwin discusses a number of traits that have been proposed to distinguish humans from other species (pp. 29-40). How does Darwin come down on each putative distinction? How does he think that humans and animals are different? How does he reconcile these differences in terms of his overall conclusion in this chapter?

 

Q8 According to Darwin, how could a moral impulse arise in humans or other animals? Consider the problem of altruism. Prairie dogs emit an alarm call when predators approach the colony, which increases the overall safety but also brings attention to the caller and increases its chance of becoming the chosen prey and decreases its chance of successful reproduction. Darwin describes a similar predicament on p. 60. How would Darwin explain the origin and persistence of altruism as a trait in animal populations?

 

Q9 What role, if any, does Darwin think that natural selection plays in what he calls “civilized nations”? How does he think that society should deal with “weak members of civilized societies” that would likely not survive in nature? How would you approach this issue?

 

Q10  Darwin’s discussion of human evolution is infused with many biases of an upper-class Victorian gentleman. What are the most prominent biases that you observe? How do they influence a) his account of human evolution, and b) the social applications of his account?

 

Q11  How does Darwin’s theory of ethics differ from accounts offered by other moral philosophers? You might consider his remarks on love and sympathy (p. 46), moral impulses (p. 54), ethical motives and ethical standards (p. 54), and the historical expansion of moral community (p. 56) as passages for thinking about these differences.
