"Over the past 20,000 years, the average volume of the human male brain has decreased from 1,500 cubic centimeters to 1,350 cc, losing a chunk the size of a tennis ball. The female brain has shrunk by about the same proportion... "This happened in China, Europe, Africa - everywhere we look." If our brain keeps dwindling at that rate over the next 20,000 years, it will start to approach the size of that found in Homo erectus, a relative that lived half a million years ago..."
An excerpt from "The Incredible Shrinking Brain," by Kathleen McAuliffe, in the September 2010 issue of Discover Magazine.
