This article focuses on the interweaving of constructive praxis with communication in ontogenesis, in phylogenesis and in biocultural niche evolution (ecogen-esis), within an EvoDevoSocio framework. I begin by discussing the nature of symbolization, its evolution from communicative signaling and its elaboration into semantic systems. I distinguish between the symbol-ready and the language-ready brain, leading to a discussion of linguistic conceptualization and its dual grounding in organism and language system. There follows an outline account of the interpenetration in the human biocultural niche-complex of semiosphere and technosphere, mediated by the evolution of the niche of infancy. Symbolization (the foundation of the semiosphere) is by definition normative; the normative character of the technosphere is demonstrated by the interrelations in human development between affordance, action schema and canonical functional object schema. A model of the neuro-computational implementation of dual grounding is proposed.
