Extract

The study of evolution by natural selection is difficult because, by definition, it occurs under uncontrolled conditions. All biological organisms are highly complex entities and their interactions with the environment and each other are unpredictable, except in the most general terms. Countless chance events impact cumulatively on the genetic composition of a descendant lineage, resulting in substantial evolutionary change over very long periods of time. Understanding how evolution works in practice is a matter for basic science, but it is attended by unique and difficult problems.
