Knowledge goals: What did Darwin mean by the term “descent with modification”? What are the four steps of evolution by natural selection (from lecture, not from the text)? Explain how the process of natural selection could result in an increased frequency of a certain

Unformatted text preview: allele over time in one environment and a decrease in that allele frequency in a different environment. What did Mayrs observations and inferences do to help people understand evolution? Be able to discuss several kinds of evidence for the theory of evolution, as well as at least two criticisms of it. What are homologous structures? Name two. What is biogeography and how does it help to explain the process of evolution? List two vestigial structures or organs. What is the adaptive landscape? How does it describe why we have such a difficult time changing our ways? What are two constraints on adaptation? Define macroevolution. How does it differ from microevolution? Why is it so difficult for scientists to agree on what a species is?...
