Emergent properties

Definition

Emergent properties refer to the complex traits or behaviors that arise from the interactions and organization of simpler components within a system. These properties are not present in the individual parts but emerge when those parts work together, showcasing a higher level of complexity that can lead to new functionalities and characteristics, especially relevant in the context of biological systems like gene circuits.
