Major Questions of Evolutionary Genetics

Among the most important questions that evolutionary genetics attempts to answer are these: What are the patterns of genetic variation within and among populations and species? What are the forces responsible for maintaining genetic variation within populations? What are the forces driving evolutionary change and, ultimately, the origin of new species? Why are there so many (or, perhaps, so few) species? How did they become so well adapted to their environments? What is the time scale for evolutionary change? What is the correct evolutionary tree for a set of species? What is the correct evolutionary history of life? Where do new genes and characters come from? Why do sex and recombination occur at all, and what are their evolutionary consequences? Where did humans come from? To what extent are humans different from other organisms?
