WASHINGTON (AFP) - – Human brains have shrunk over the past 30,000 years, puzzling scientists who argue it is not a sign we are growing dumber but that evolution is making the key motor leaner and more efficient. The average size of modern humans -- Homo sapiens -- has decreased about 10 percent during that period -- from 1,500 to 1,359 cubic centimeters, the size of a tennis ball. Women's brains, which are smaller on average than those of men, have experienced an equivalent drop in size. These measurements were taken using skulls found in Europe, the Middle East and Asia. "I'd called that a major downsizing in an evolutionary eye blink," John Hawks of the University of Michigan told Discover magazine.
