Document Summary
Comment on coyne"s prose in his discussion of the asian giant hornet. Discuss his use of adjectives and metaphors: discuss three different examples of co-evolutionary arms races. Evolution even occurs within the body of a single patient, since the virus mutates at a furious pace, eventually producing resistance and rendering azt ineffective. Now we keep aids at bay with a daily three-drug cocktail, and if history is any guide, this too will eventually stop working. Individual, lion example a: peacock example, deer antlers example, the forces of evolution are natural selection, mutation, gene flow, and genetic drift. Explain why only natural selection is responsible for adaptation: selection is not a mechanism imposed on a population from outside. It is a powerful molding force, accumulating genes that have a greater chance of being passed on than others, and in so doing making individuals ever better able to cope with their environment.
