As the glaciers of the last Ice Age receded, humans ventured into the far north, exploring a wild, fertile territory. Nomadic hunter-gatherers at first, they made the decision to stay for good - to farm and to build. The landscapes they lived on were remarkable in their diversity. Vast forests of pine and birch ran through one of the world's oldest mountain ranges - once as high as the Himalayas but over millennia scoured and compressed by sheets of ice a mile thick. On hundreds of islands around a saw-edged coastline, communities flourished, linked to each other and the wider world by the sea, the transport superhighway of ancient times. It was a place of challenges and opportunity. A place we know today as Scotland. Over the past 10,000 years, every inch of Scotland - whether remote hilltop, fertile floodplain, or storm-lashed coastline - has been shaped, changed and moulded by its people. No part of the land is without its human story.
