Evolutionary change in a phenotype results from changes in the underlying genetic composition of a population. These changes can be caused by a variety of factors, including genetic drift, mutations, migration, natural selection, and sexual selection. While changes in the environment can influence the direction and rate of evolutionary change, they do not directly cause genetic changes. Furthermore, evolutionary change in a phenotype can be passed from parent to offspring through the inheritance of genetic traits.
