A bit lighter than usual. My thoughts on the caveman. To clarify before the inevitable comments: Our intelligence has shown an increase over time, yes. There are likely a number of reasons, from atmosphere to diet to leisure time. The point of this video is not to explain the science of judging intelligence over history, but to contemplate on how we treat humans of the past. Also, the Areni 1 cave winery is over 6000 years, not 8000. That slipped in to two videos somehow without us noticing.
