Researchers found 24 ancient breadcrumbs from the world's oldest bread. They found them on a dig in Jordan. They were burnt, which is how they have survived. The crumbs are about 14,000 years old. This means that Stone Age people who lived from 12,500 to 9,500 B.C. were baking bread. This is 4,000 years earlier than we thought. They were hunter-gatherers. The people lived thousands of years before humans became farmers.
The breadcrumbs were made from barley, wheat and oats. The bread took a long time to make. The ancient people made flour and mixed it with water. After that, they baked it in hot ashes or on a hot stone. The bread looked like flat pitta bread. Another researcher said the bread could be a reason why the agricultural revolution started. Stone Age people understood it was easier to farm the wheat instead of getting it from the wild.
