What significant similarity does Gould point out between the process of natural selection proposed by Darwin and the characteristics of rational economy as described by Adam Smith?

Gould highlights that both Darwin's natural selection and Adam Smith's rational economy operate through decentralized processes that lead to complex outcomes without central planning. In natural selection, individual organisms adapt to their environments, while in a rational economy, individual market participants make decisions based on their own interests. Both systems rely on the aggregate effects of individual actions to drive evolution or economic progress, demonstrating a parallel in how order arises from seemingly chaotic interactions.
