historical population genetics

Historical population genetics studies how the genetic makeup of groups changes over time due to factors like migration, mutation, natural selection, and genetic drift. By analyzing DNA from different populations and comparing genetic markers, scientists can trace ancestral relationships, migration patterns, and adaptations. This field helps us understand human history, how populations have interacted, and how genetic diversity has developed. It combines genetics, archaeology, and history to reconstruct the evolutionary story of populations over thousands of years, revealing insights into our shared origins and biological connections.
