They used to think that cereals and grains entered the human diet about 20,000 years ago, that it was a relatively modern human behaviour. Now, a Canadian team working in a cave in Mozambique has found that long before there were Quakers and organized farming, people were grinding and processing wild grass grains. Julio Mercader, from the University of Calgary, told the Telegraph:
''This broadens the timeline for the use of grass seeds by our species, and is proof of an expanded and sophisticated diet much earlier than we believed. This happened during the Middle Stone Age, a time when the collecting of wild grains has conventionally been perceived as an irrelevant activity and not as important as that of roots, fruits and nuts.''
And probably went very nicely with the Oysters that saved the Human Race

"It has been hypothesised that starch use represents a critical step in human evolution by improving the quality of the diet in the African savannahs and woodlands where the modern human line first evolved. This could be considered one of the earliest examples of this dietary transformation.
''The inclusion of cereals in our diet is considered an important step in human evolution because of the technical complexity and the culinary manipulation that are required to turn grains into staples.''
Canada.com reports that Mercader also found a stone age pantry with legumes, wild oranges and tubers, indicating that our ancestors had a "sophisticated and expanded diet."
