Final answer:
Evolutionary change is the process of progressive genetic improvement in populations. It is influenced by factors such as natural selection, genetic drift, mutation, and migration. In the case of artificial selection, humans select which individuals are allowed to reproduce based on traits useful to them.
Step-by-step explanation:
The process of progressive genetic improvement in populations constitutes the process of evolutionary change . This process occurs as a result of various factors, including natural selection, genetic drift, mutation, and migration. In the case of artificial selection, which is a type of evolutionary change, humans select which individuals are allowed to reproduce and pass on their genes to successive generations based on the traits they find useful.
