HT Henry Warwick, but I'm afraid he's very very short on facts. I certainly resonate with the idea, knowing how much my amygdala flips out with bliss whenever I swallow something with cholesterol in it. Surely it was a good survival mechanism in an environment without much cholesterol. But like a lot of survivor mechanisms, it proves fatal when there's a different environment (the Anthropocene).
Strange, yes? The death drive latent in the survival mode really kicks in in a consumerist economy.
I recently read some evidence that Palaeolithic humans made bread. And I'm very happy to be a vegan right now. And so is the climate.
And he's flat wrong about flour milling. There were no mills until 1880? This guy is a joke. Another very good reason not to listen to scientists on (human) history. Did he ever read Chaucer?
Just because humans didn't get a lot of calories out of whatever they did, doesn't mean they didn't do it. We do a lot of energy expensive things.
