The makeup of our genome (and therefore our physiology) is the result of millions of years of evolution under the selective pressures of our environment, as well as competition for survival. If we consider a simple view from evolutionary theory, certain physical traits that provided our ancestors with a competitive advantage allowed those individuals to thrive and bear offspring, while individuals that lacked a given competitive advantage were much less likely to thrive and bear offspring. Therefore the individuals that harbored advantageous traits passed their genes onto their offspring, and after thousands of generations of human evolution, the content of our genome is the result of this evolutionary process
