Certain outcomes can be classified as emergent, meaning no other outcome was possible, meaning the discovered outcome was inevitable on a sufficient time horizon for it to emerge.

Examples:

- out of the phenomenon 'life' emerges energy use efficiency.

- out of the phenomenon 'vibration' emerges harmonics

- out of the phenomenon 'entropy' emerges uncertainty

- out of the phenomenon 'memory' emerges concept of time

- out of the phenomenon 'fractional reserve banking' emerges expansion of currency units

This list is endless, and clarifying emergence can help us understand large systems.
