What discovery makes the scientists surprising?

The burned remains of bread made about 14,500 years ago in northeastern Jordan have given scientists a surprise：humans started making bread long before they developed agriculture. The bread was found in a stone fireplace at an ancient site in Jordan’s Black Desert. It is the oldest bread ever found. Researchers said that the discovery shows that hunter-gatherers in the Eastern Mediterranean learned to make bread more than 4,000 years before farming began.
