Are modern comforts drastically changing our evolutionary trajectory? Some researchers think so, arguing that the developed world’s standard of living may be holding back the evolution of mankind.  British genetics expert Steve Jones recently extending his theory that our standard of living and healthcare greatly reduces the influence of mutation, random change and natural selection, the three major forces of evolution. Modern-day medicine brings opportunities to those who would never survive in the times of our ancestors: “In a modern world of central heating and plenty of food, the same mutation is far less likely to give a child any advantage. A baby born today can expect to live a long and healthy life, which in turn works against the evolutionary tool of natural selection.”
