A study published by the Proceedings of the National Academy of Sciences has found that prehistoric men could process starch grains and grind them into flour to make paste and primitive baked goods 32,000 years ago.
An analysis carried out by archeologists unveiled that early humans ate seeds, cattails and ferns and the flour they made hardly resembled flour used in modern times.
Scientists suggest that the flour was used to cook flatbread or paste, which supplemented the meat diet of prehistoric man. It was earlier believed that humans were primarily carnivores.
