自下而上：万物进化简史

Ridley's analogy between natural selection and innovation made me think differently about how progress actually happens. I wonder what led him to make that connection.

While the concept is fascinating, I was curious whether certain comparisons felt a bit forced or if they really hold up across different domains of change.

The stories he chose were compelling, but I wonder if he had a specific framework for selecting these examples or if they evolved during writing.
