It is possible that early humans diverged from other primates when they began eating meat. This meat was likely burnt from frequent lightning strikes on the African savanna. They did not even have to know how start a fire, only how to keep one going. Eating cooked meat gave a much higher caloric intake and human brains grew significantly larger than their primate cousins. As humans developed a taste for meat and a source of constant fire at their campsites, they had to work together socially. Hunting or gathering during the day was very task-focused but in the evening groups of our ancestors sat around the fire for protection. This is where storytelling began. Modern day Ju/’hoansi of the Kalahari Desert reflect this in their daily routine — ‘daytime talk’ and ‘fireside talk’ are quite different. The vocabulary of the latter is much larger and evenings are much more engaged in storytelling.
This is one of the initial premises of Edward O. Wilson’s book, The Origins of Creativity. We all belong to, and still carry some of the attributes, of this early tribe. The creative arts, enabled by our ability to share language, are what makes us human. But the study of the humanities has lost its way, says Wilson.
