It is called Unnatural Selection by laidnyc
Once upon a time the harsh winter of northern latitudes brought forth a great selective pressure upon its human inhabitants. The challenges of the terrain selected for the clever, and the cold climate allowed brains to expand with little metabolic cost. The minds it shaped brought forth innovation, first benefitting themselves and their spawn. Then capital, markets and money coevolved with agriculture and eventually developed into an Industrial Revolution to solve problems for the masses at a low price of $19.95. Now western humanity has all the comfort and prosperity that 99.9% of humans did not have throughout history, with none of the brainpower required. More.
