2) The Roess Anatomy Scale (A0–A5) → 1–10
Purpose. The Roess Anatomy Scale (A0–A5), indexed to a 1–10 score,
formalizes anatomical readiness for symbolic cognition—tracking cranial
capacity and shape, facial/pelvic gracility, respiratory–vocal tract proxies,
manual fine-motor anatomy, and life-history/neoteny signals. It is a
framework, not a value judgment.
Authorship note. The scale is my conceptual contribution (Roess, 2025).
Empirical anchors (Irhoud, Omo I, Herto, etc.) are cited from the literature
and used to illustrate the scale (e.g., [Hublin et al., 2017; McDougall et al.,
2005; White et al., 2003; Neubauer et al., 2018]).

3) Hardware Without the Flame: The Anatomy Plateau
By ~200–160 kya, anatomical modernity is established: Omo I (~195 kya),
Herto (~160 kya), and Jebel Irhoud (~315 kya: modern face, archaic vault) fall
within or near modern cranial volumes and morphologies [McDougall et al.,
2005; White et al., 2003; Hublin et al., 2017]. Globularity (parietal expansion)
continues to evolve within H. sapiens, with connectivity implications for
language and social cognition [Neubauer et al., 2018].
“Anatomical modernity long preceded behavioral modernity. Clearly, some additional factor
intervened to trigger the qualitative leap.
