Before revision: I revisit two theories of cell differentiation in URLanisms published a half-century ago, Stuart Kauffman's global gene regulatory dynamics ( GRGD ) model and Roy Britten's and Eric Davidson's modular gene regulatory network (MGRN) model, in light of newer knowledge of mechanisms of gene regulation in the metazoans (animals).
