# C. Titus Brown > **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:** Computational Biology / Digital Evolution **Doc Type:** Canonical Wiki Node **Maturity:** Developed ## Definition C. Titus Brown is a computational biologist and software researcher who co-developed the early Avida platform. ## Nexus Context His role connects artificial life, executable evolutionary experiments and later computational biology infrastructure. ## Evidence Boundary Authorship and institutional affiliations should follow the chronology of each paper; later Avida results involved a wider team. ## Relationships [[wiki/Avida|Avida]], [[wiki/Christoph Adami|Christoph Adami]], [[wiki/Charles Ofria|Charles Ofria]], [[wiki/Computational Biology|Computational Biology]] ## Sources / Provenance - NASA Astrobiology, “Computing the Origin of Life”; Avida histories.
