U_4_03 — Cultural Evolution — Dual Inheritance and Cumulative Culture
Cultural evolution theory applies Darwinian principles — variation, selection, inheritance — to the transmission and transformation of cultural information (beliefs, technologies, norms, institutions). The dual inheritan
X_1_09 — Caduceus & Medical Symbolism: Serpent-Healing Connection
