About 12,000 years ago, our human ancestors, who once lived as hunter-gatherers, began doing things differently. They started growing crops, domesticating animals, and using new tools. The way people inhabited the landscape also changed as they built some of the first settlements and monuments.

This cultural transition, often called the Neolithic Revolution, was a turning point in prehistory. However, with no existing written records, it’s difficult to truly understand why this shift occurred, how Neolithic societies functioned, and why they built grand monuments, like Stonehenge. Hear how archaeologists, like Dr. Jim Leary of the University of York, are piecing together some of the ancient clues left behind in earth and stone.
