Summary:
"What was life on earth like two million years ago? A thousand years ago? The years in between? When did people start wearing clothes? When did farming begin, and how did that change things? This series takes you back to the time of the earliest humans. The dinosaurs were long gone, but the world was still strange and wild."--Back cover.
