Natural Selection

Natural Selection

Definition: natural selection

natural selection: the process of evolutionary change, by which offspring of organisms with certain characteristics are more able to survive and reproduce than offspring of other organisms, thus gradually changing the composition of a population. Understanding natural selection can help farmers with livestock breeding programs. By selecting animals with desirable traits such as disease resistance, productivity, and adaptability, farmers can improve herd or flock performance over time. This knowledge supports the development of robust livestock populations that are better suited to local conditions and market demands.
