Genetic evolution is the study of how genetic variation within populations changes over time through the process of natural selection, genetic drift, and gene flow. This field of research focuses on understanding how genetic factors influence the evolution of species and populations, including how new species arise and how genetic traits are passed down from generation to generation. By studying genetic evolution, scientists can gain insights into the mechanisms driving evolutionary change and the diversity of life on Earth. This research area is important for understanding the genetic basis of traits, adaptation to changing environments, and the origins of genetic diseases.
