# Evolutionary Dynamics > **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] places this concept within the history and governance of substrate-independent evolution. **Domain:** Evolution / Population Processes **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Evolutionary dynamics studies how mutation, selection, drift, recombination, spatial structure and interaction change populations over time. ## Machine-Evolution Context Digital systems make many such dynamics fully observable because every instruction, birth, mutation and lineage can be logged. This turns evolution into an experimental generator of data. ## Continuity and Evidence Boundary A changing model or software ecosystem is not automatically an evolutionary population; the units, inheritance path and selection environment must be specified. ## Relationships [[wiki/Population Dynamics|Population Dynamics]], [[wiki/Mutation Rate|Mutation Rate]], [[wiki/Fitness Landscape|Fitness Landscape]], [[wiki/Evolving Population|Evolving Population]] ## Sources / Provenance - Nowak, _Evolutionary Dynamics_ (2006); Avida literature.
