This week on History Happy Hour: What better topic for our hoist-a-glass history show than the role of intoxication in the rise of civilization?

Drinks in hand, host Historians Chris Anderson and Rick Beyer welcome Edward Slingerland, author of "Drunk: How We Sipped, Danced, and Stumbled Our Way to Civilization." Find out how evidence from archaeology, history, neuroscience, and genetics suggests our taste for chemical intoxicants isn’t a flaw – it has helped solve a number of distinctively human challenges. The historical impact of humanity’s appetite for getting juiced up. Sunday at 4PM ET on History Happy Hour, the spot where history is always on tap.
