# Genomic Complexity > **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 / Information **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Genomic complexity is the amount or organization of functional hereditary information in a genome, measured relative to an environment and method. ## Nexus Context Avida permits complete lineage records and controlled environments, allowing researchers to track how functional information can accumulate through mutation and selection. ## Evidence Boundary Genome length alone is not complexity, and model-specific metrics should not be treated as universal measures of biological or cognitive sophistication. ## Relationships [[wiki/Genome|Genome]], [[wiki/Avida|Avida]], [[wiki/Complexity|Complexity]], [[wiki/Evolutionary Covariation|Evolutionary Covariation]] ## Sources / Provenance - Lenski et al. and Avida complexity literature; Adami’s information-theoretic work.
