Grinding Grain. It now seems that humans began to grind grain into flour earlier than was originally thought. Grinding stones have been found at African and Asian sites dating from 200,000-50,000 years ago It was presumed at first that these stones were used primarily to grind plant and animal materials, or minerals, to make pigments, rather than for the preparation of …
