Having read a fair amount of Origin of Species (which is fascinating to read as a primary source), I'd say The Selfish Gene is where anyone should start enhancing their understanding of evolutionary biology. He uses all the tools Darwin didn't have at their disposal: game theory, genetics, modern medicine, and many others.
