The theory I'm putting forward here is that storytelling is a genetic characteristic in the sense that early human hunters who were able to organize events into stories were more successful than hunters who weren't—and this success translated directly into reproductive success. In other words, hunters who were storytellers tended to be better represented in the gene pool than hunters who weren't, which (incidentally) accounts for the fact that storytelling isn't just found here and there among human cultures, it's found universally.
