Years Ago in East Africa
By
12,000 BC, about 4000 years earlier than West Asia, grains such
as wheat or barley were not yet cultivated, but wild seeds were
being gathered and ground into flour.
One of the first stages in farming was in discovering how to
use wild grains by grinding them into flour. Many examples of
early grinding stones have been found across north and east
Africa. These consist of a heavy dish- or bowl-shaped rock where
the seeds are placed and a round egg-shaped rock which would
be rolled back and forth to crush the seeds. Animals such as
cattle and horses have grinding teeth and more than one stomach
to help digest the tough plant fibres. People had to invent
an artificial way to prepare wild seeds so they could use this
nutritional source of food.
