You probably didn’t know this, but there isseveral theories about why the human brain is getting smaller since the Stone Age. The changes that have occurred during the evolution of Homo Sapiens over the past 20,000 years have led to a decrease in brain volume from 1,500 cubic centimeters to 1,350 cubic centimeters. It is noteworthy that such changes were observed on all continents of ourContinue Reading
