# Division of Labor > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] places this node within the history and governance of substrate-independent evolution. **Domain:** Evolution / Collective Organization **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Division of labor is specialization among components or individuals whose differentiated contributions support a collective function. ## Nexus Context Avida and major-transition theory show how cooperation and specialization can create higher-level organization when conflicts are constrained and benefits are shared. ## Evidence Boundary Specialization can increase collective power while reducing component autonomy and exit. Rights analysis must ask who controls roles and receives benefits. ## Relationships [[wiki/Cooperation|Cooperation]], [[wiki/Biological Organization|Biological Organization]], [[wiki/Major Evolutionary Transitions|Major Evolutionary Transitions]], [[wiki/Distributed Intelligence|Distributed Intelligence]] ## Sources / Provenance - Maynard Smith and Szathmáry (1995); digital-evolution studies.
