Evolutionary biologists have developed many techniques to analyze how male and female mating preferences have co-evolved. These studies combine animal behavior, sensory biology, phylogenetics, and neurobiology to observe the effects of male trait biases based on female receiver systems; that is, the "attractiveness" of the male trait to potential female mating partners.

In this case study, we'll follow the process of developing an edible vaccine for the hepatitis B virus and explore practical details of genetic engineering techniques. 

"Designing drugs" sounds trendy, but it accurately describes how some remarkably effective drugs are developed. In this case study we'll follow the steps of drug design, from initial research on the targeted disease, to the drug's use in humans. Gleevec (STI-571) is our example.
