Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Not only was the idea capable of generating a prediction, that prediction was verified through empirical study. Differential survival or reproduction ("SELECTION") due to variation at the trait.

Capture sunlight for photosynthesis. It is one of five types of selection processes used in evolution: The others are directional selection (which decreases the genetic variation), diversifying or disruptive selection (which shifts genetic variation to adjust to environmental changes), sexual selection (which defines and adapts to notions of "attractive" features of the individuals), and artificial selection (which is the deliberate selection by humans, such as that of the processes of animal and plant domestication).
