Population genetics is the scientific study of how genes evolve, how they are inherited, and how genetic variation is distributed across human populations. By examining allele frequencies , mutations , and evolutionary pressures , this field provides crucial insights into human evolution, migration, and adaptation across different environmental and cultural contexts. Researchers in this area explore how populations change over time, how genetic diversity is maintained or lost, and how natural selection , genetic drift , and gene flow shape the characteristics of entire communities. This knowledge allows scientists to reconstruct ancestral lineages and better understand the complex interplay between genes and environment throughout human history. Although humans across the globe may appear highly diverse in physical traits such as skin color, facial features, or body structure, the genetic blueprint shared by all humans is remarkably similar. These apparent differ...
