Mythos & Symbolic Humanity presents an integrated literary–scientific exploration of the emergence of symbolic behavior in the human lineage. Part I (Mythos) is a research-informed narrative following a small hominin family—Tod, Zoe, and child Toumai—across deep time nodes of tool innovation, fire use, and communicative complexity. Archetypal figures (e.g., "Rock Man") embody material and cognitive thresholds familiar from paleoarchaeology. Part II (The Ten Nodes of Symbolic Humanity) provides the underlying scholarly synthesis: paleoanthropological evidence for tool traditions (Acheulean, proto-Levallois), early fire control and possible pyrite-based ignition, eco-stress drivers, developmental analogs for language emergence, and the conceptual framework of symbolic nodes. By pairing narrative embodiment with annotated scientific analysis, the volume invites interdisciplinary engagement from anthropologists, educators, and readers seeking empirically grounded prehistorical imagination.
