Natural selection and ecological interactions at work are the reason why forests maintain complex ecosystems without intent. Each species adapts to its environment for survival and reproduction, each forming a complex network with other organisms and the environment. This interaction builds up and results in the complexity of the entire ecosystem. Even without intention or purpose, the natural processes of evolution over time and adaptation to changes in the environment support the diversity and stability of the forest.
Yes, the complexity of the forest is due to the accumulation of local optimizations. Each species and plant adapts to its own survival environment and finds locally optimal solutions through resource use, competition, and symbiotic relationships. These local optimizations interact with each other to maintain the complexity and stability of the ecosystem as a whole. Even though there is no intentional overall design, individual local optimizations create balance and diversity in the forest as a whole.
That’s right. Similarly in markets, the overall dynamic is created by individual players making self-interested, optimal choices. Firms and individuals trade and invest to maximize profits, and dynamic changes in supply and demand adjust market prices and the distribution of resources. In this way, individual self-interested actions often accumulate, resulting in the efficient functioning of the market as a whole. This phenomenon, also known as Adam Smith’s “invisible hand,” is a classic example of order emerging without deliberate central planning.
