“Our bodies are designed for people who used to walk 20 miles each day looking for food and water”, says Professor Randolph Nesse.
People become ill because their bodies are unable to cope with the pressures of modern Western life, according to a leading scientist.
Professor Randolph Nesse believes that conditions like heart disease, obesity and drug abuse can all be explained by the fact that the human body was not designed for the 21st Century.
He suggests many serious illnesses occur because the human body has failed to evolve and is still designed for a much simpler existence.
Dr Nesse, who is professor of psychiatry at the University of Michigan, is one of the leading proponents of evolutionary or Darwinian medicine.
