# Rosalind Franklin > **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:** Chemistry / X-ray Crystallography **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition Rosalind Franklin was a chemist and X-ray crystallographer whose measurements and analysis were crucial to establishing DNA’s helical structure and dimensions. ## Nexus Context Her work supplies the article’s reminder that hereditary architecture became legible through instrumentation and collaborative evidence, not conceptual elegance alone. ## Evidence Boundary A rigorous history distinguishes her direct experimental contribution from later narratives that minimized it, while avoiding claims unsupported by the surviving record. ## Relationships [[wiki/X-ray Diffraction|X-ray Diffraction]], [[wiki/Double Helix|Double Helix]], [[wiki/DNA|DNA]], [[wiki/Maurice Wilkins|Maurice Wilkins]] ## Sources / Provenance - Franklin and Gosling, “Molecular Configuration in Sodium Thymonucleate,” _Nature_ 171 (1953).
