Assignment:
1. Origin of species: What are the basic tenets of Darwin's thesis? What term did Darwin use for now what we call evolution? Why did he not like the term evolution?
2. Emerging definitions of a gene: How has evo-devo changed our definition of gene? What are only transcribing genes? "
On natural selection
3. Why is it critical to include differential reproduction in in a definition of natural selection? Which did Darwin emphasize, survival or reproduction, and why?
On natural selection two
4. What are correlations? Using a two-dimensional graph, how can you gather positive evidence for the "strength" of a fit between two variables?
5. How did Snow use correlation to support his hypothesis that cholera was water borne? Why did he bother to look at outlier points?
6. Understand two allele/locus models that display positive selection or genetic drift over time. Be able to explain the patterns generated. Remember these models can be used to pattern of genetic drift as well as natural selection. (View genetic drift online notes)
7. What are natural experiments and how do they serve as example of natural selection on population? How are current pollution problems in co-inhabiting lake species of cichlid species, providing evidence for past selection acting on the species' mating systems?
