A recent study found that human brains have decreased in volume by roughly 150 cubic centimeters over the past 3,000 to 5,000 years,that's about the size of a tennis ball. Scientists are baffled by the shrinkage and have no clear explanation for why our brains are now significantly smaller than those of our ancestors.
