T1, E1: Extraordinary new discoveries suggest that civilization as we know it began 12,000 years ago.

See how recent excavations are rewriting the first chapter in man's long journey to civilization. Then track how these ancient societies expanded to Africa, Europe, and ultimately became inexorably linked with the Western world, thanks, in large part, to the conquests of Alexander the Great.
