# Genetic Recombination
**Domain:** Genetics / Inheritance / Variation
**Doc Type:** Canonical Concept Node
**Maturity:** Foundational
## Definition
**Genetic recombination** creates new combinations of genetic material through exchange or reassortment of DNA.
## Evolutionary Nexus
Joshua Lederberg's Nobel-recognized bacterial work showed that bacterial inheritance could include recombination rather than simple clonal copying. [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] places this discovery upstream of his AI and exobiology work.
## Continuity Context
Recombination makes descent reticulate. A descendant can inherit from multiple sources, strengthening the need to distinguish provenance from identity in merged models and reconstructed persons.
