Did fire help humans bond? I’m Bob Hirshon and this is Science Update.
[storytelling around fire]
Around a campfire in the Kalahari Desert, a !Kung woman shares a story about a long journey and strange foreigners. The story’s unique, but the experience of sharing around a campfire is universal and primal. University of Utah anthropologist Polly Wiessner studies how human society may have changed when fire let us extend our days.
POLLY WIESSNER (University of Utah):
You extend the day by four or five hours and produce time and space that cannot be used for any productive activities.
HIRSHON:
In the Proceedings of the National Academy of Sciences, she compares the conversations Kung people have during the day with those at night, around a fire. She theorizes that fire drew people close and helped catalyze the social bonding that defines us as a species today. I’m Bob Hirshon, for AAAS, the science society.
