A child plants an acorn. An oak tree sprouts. For the next two hundred years, generations of people come and go, but the tree remains standing strong, sole witness to the remarkable changes taking place all around it. This inventive picture book relays history from a unique perspective, showing how much the world can transform from a single vantage point. In the span of two hundred years, methods of transportation, communication and energy use progress rapidly while other things hardly seem to change at all. Perfect for budding historians and nature enthusiasts alike, the time-lapse quality of the detail-packed illustrations will draw readers in as they pore over each spread to spot the changes that come with each new era. A fact-filled poster is included to add to the fun. Praise for G. Brain KarasOn Earth'Original and appealing . . .
