“In most parts of the world natural selection no longer operates the way it does in the wild due to agricultural and medical advancements and cultural and societal changes. These changes have lowered the genetic bar for survival significantly – have almost gotten rid of the bar altogether. Advancements in labor saving devices and easy access to calorie dense food have compounded this by minimizing the physical effort required for daily survival to practically nothing, resulting in a society that is mostly weak, slow and fat. Most people alive now in developed countries would be incapable of handling the physical demands of the day to day lives of our ancestors, and would have no hope of surviving in such an environment.”
