A while back I was reading Yuval Harari s book Sapiens and came across the idea. Now, having read both works of serious history and works like "A history of English speaking peoples", I got a feeling that the work was more akin to the story telling rather than history - which by itself is not bad. The only caveat there is perhaps, that one should hear the same story through other perspectives to gain the understanding of history.

With that in mind, is it a valid idea? What does it constitute ? And what were the causes and effects of the cognitive revolution among humans and could we possibly see something similar happening to another mammal - if not our other great ape cousins ?
