Evolutionary events occur over long periods of time and at the molecular level.
Because of this, it is very difficult to study evolution itself. To get around this, scientists often use simplified representations of nature called models . In order to interpret the results of a model, first you must have an understanding of how the model works and what its limitations are. About the model This model of evolution uses imaginary organisms called Driftworms. This simulation allows you to visualize the evolution of color in a population of driftworms.
