Branching Descent - Bryant McGill

# Branching Descent **Entity class:** Concept or analytic term > **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:** Lineage / Continuity / Technology **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Branching descent occurs when one ancestral state or lineage gives rise to multiple continuing descendants. ## Nexus Context It describes species divergence, software forks, blockchains and copied persons at a shared structural level while allowing their mechanisms to differ. ## Evidence Boundary Common ancestry does not make descendants numerically identical to the ancestor or one another. A fork creates a continuity problem, not its automatic solution. ## Relationships [[wiki/Lineage|Lineage]], [[wiki/Descent with Modification|Descent with Modification]], [[wiki/Hard Fork|Hard Fork]], [[wiki/Forked Continuity|Forked Continuity]]  This entry is routed through [[collections/Consciousness Continuity|Consciousness Continuity]], [[collections/Neurotech|Neurotech]], and [[collections/Machine Succession|Machine Succession]].
