Reading Passage:->
Scant physical evidence remains of the first human domestication of grain. Still, there is enough to conclude that ancient peoples, motivated by the nutritional value of bread or cakes make of wild wheat, looked for controlled ways to grow ut to provide a consistent food supply. Three related discoveries are likely to have led to the introduction of bread as the first grain-based food.

The first discovery was that wheat could be prepared for use by grinding. People probably began consuming wheat by chewing it raw. Because wheat is very hard, they gradually discovered that it was less trouble to eat if crush to paste between two stones. The result would have been the ancestor of the drier more powdery wheat flour we use today.

From there, it was a short step to the next breakthrough- baking the simplest brand, which requires no technology but fire. Loaves of wheat past, when baked into bread, could be stored for long periods, certainly longer than raw seeds. This kept the food value of wheat available for and extended period after it had been harvested.

Finally, ancient peoples found that, if the paste was allowed to sit in the open, yeast spores from the air settled on it and began fermenting the wheat. This natural process of fermentation caused bubbles to form in the wheat paste, suggesting that it would be lighter in texture and even easier to eat when baked.
