Jared Diamond, an American evolutionary biologist, physiologist, bio-geographer and non-fiction author, wrote a remarkable piece for Discover Magazine, in May 1987.
It is about; how agriculture set the stage for class division, and is responsible for many of the modern health problems. Jared Diamond was an influence for me when I was seeking answers about modern lifestyle problems, and indeed, he's a man who has inspired me to make this website.
From the article:"...recent discoveries suggest that the adoption of agriculture, supposedly our most decisive step toward a better life, was in many ways a catastrophe from which we have never recovered. With agriculture came the gross social and sexual inequality, the disease and despotism, that curse our existence."
