# Artificial Selection > **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 / Breeding / Governance **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Artificial selection is differential reproduction directed by human choices about which variants breed or persist. ## Nexus Context Genetic algorithms and current evolvable-AI techniques usually operate in this breeder regime because designers choose encodings, objectives and retention rules. ## Evidence Boundary Human direction does not eliminate evolution, but it changes control, fitness and accountability. Selection criteria can still produce unexpected or harmful solutions. ## Relationships [[wiki/Breeder Scenario|Breeder Scenario]], [[wiki/Genetic Algorithm|Genetic Algorithm]], [[wiki/Natural Selection|Natural Selection]], [[wiki/Objective Function|Objective Function]] ## Sources / Provenance - Darwin’s comparison of artificial and natural selection; evolutionary-computation literature.
