Kalahari Bushman Storyteller (IMAGE) University of Utah Caption A !Kung Bushman, sporting a Calvin Klein hat, tells stories at a firelight gathering in Africa's Kalahari Desert. University of Utah anthropologist Polly Wiessner has published a new study of the Bushmen suggesting that when firelight extended the day for human ancestors, stories told around the campfire helped stimulate human mental, social and cultural development.
