Human beings first made tools in the Old Stone Age. You may think making a stone tool would be easy. Dietrich Stout, an anthropology professor at Emory University, wrote in the journal Scientific American that making a hand axe took him 300 hours. Professor Stout monitored his brain activity during the tool-making process. He said that human beings may have developed communication skills by talking to each other when they made stone tools.
