What Made Early Humans Smart
It&#x27;s an interesting piece of natural history and discussion. It talks about some of the things that made smartness <i>possible</i>, including big brains and roaming around. However it doesn&#x27;t seem to address the question of what actually made us smart.<p>My answer would be: our genes, and later on our culture too, began to optimise for meme transmission and storage. This process snowballed and we went further down that route than any other species.
