Researchers have found the world's oldest [exemplar / example] of bread. A research team from the universities [of / for] Cambridge, Copenhagen and London found ancient breadcrumbs while on an archaeological [dig / digger] in Jordan. The breadcrumbs were charred and [burning / burnt] , which is how they survived for so [length / long] . The researchers dated the crumbs and found they were roughly 14,400 years old. This [meaning / means] that people in the Stone Age were [baking / baked] bread. The researchers said humans were making bread 4,000 years earlier than scientists [thought / taught] . The people who baked the bread lived [in / on] Jordan from around 12,500 to 9,500 B.C. They were hunter-gatherers and lived thousands of years before humans settled [up / down] to become farmers.
The researchers [discovered / discovery] 24 burnt breadcrumbs. They analyzed them and found they were made from [serial / cereal] plants such as barley, wheat and [oat / oats] . Lead researcher, Dr Amaia Otaegui, said the bread took a long time [for / to] make. The ancient Jordanians began by grinding cereals into a [fine / finely] flour. They then mixed the flour with water to make dough. After that, they baked [them / it] in the hot ashes of a fireplace or on a hot stone. The bread looked like the flat pitta bread still made [across / cross] the Middle East today. Another researcher said the bread could be one [reason / reasoning] for the agricultural revolution starting. Stone Age people realized it was easier and more [convenience / convenient] to farm the wheat for bread instead of [gathering / gather] it from the wild.
