Evolutionary genetics is the branch of genetics that deals with the study of genetic changes in populations over time, and their role in evolution. Synonyms for this term may include evolutionary biology, population genetics, evolutionary genomics, and molecular evolution. All of these terms encompass aspects of the genetic changes that occur within and between populations, and the mechanisms driving evolutionary change. By studying these processes, we gain a deeper understanding of how species have evolved over time and why they have developed certain traits or adaptations. The field of evolutionary genetics is dynamic, interdisciplinary, and presents exciting opportunities for new discoveries in genetics and biology.
