Evolution

Definition of Evolution as it relates to Science, Genetics, Natural Selection, Mutation

Evolution, as a concept within the field of genetics and natural selection, refers to the gradual changes in heritable traits over generations in populations of organisms. It is the process by which diversity among species arises and new species emerge through the descent with modification from common ancestors. In this hierarchy, it falls under the broader category of mutation, as genetic variation through mutation provides the raw material for natural selection to act upon, driving evolutionary change. Evolution encompasses mechanisms such as gene flow, genetic drift, and natural selection, which result in changes in allele frequencies within populations over time. It is an essential principle in understanding the diversity of life on Earth and the relationships among different species.
