Homo sapiens have remained the same species, largely unchanged in genetic makeup and anatomy since the Cro-Magnon era. By contrast, the cultural, social, and technological changes since then have been nothing less than extraordinary. At the core of this development is the ability of humans to store and transmit knowledge, so that each new generation stands upon the shoulders of its predecessors. This ability to use what has gone before is what sets humans apart. Telling our story, from prehistory to the present day, DK's "History" is a thought-provoking journey, revealing the common threads and forces that have shaped human history. Taking a broad-themed approach, acknowledging varied factors at work, from climate, ecology, disease, and geology and their roles in the human story, this visual celebration makes history accessible and relevant, putting events in their wider context and showing how they have shaped the world we live in.
