Each individual who survives on this Earth is incredibly unique in every way. Although man descends from a common ancestor, he has progressively accumulated various changes over a long period of time. These changes are a gradual process that leads to the change in genetic frequencies of a population and, over time, results in their different genetic composition. One individual differs from another not only in terms of physical appearance such as height, weight, skin color, nose design, facial appearance, etc., but also has different eating habits, behavior and culture. The physical variation observed among human populations surviving in different geographic regions of the world or even those in the same region is clear evidence of ever-evolving human evolution. Diverse human populations live in groups over large geographic regions and exhibit broad socio-cultural differences. attributes. The biology of a population is governed by a complex interaction of environmental and genetic factors. The genetic constitution of a population in interaction with the environment ...
