Emergence definition

The structure that grows from a bird's skin, comprising a shaft with interlocking barbs, arises from the unique combination of the bird's ability to interact with and respond to its environment and the skin's role as a covering for the body, enabling the creation of a light, flat, and insulating feature that facilitates flight.
