Now, the European Union is formalizing a path away from that tradition, publishing a roadmap to phase out animal testing in chemical safety assessment and centering its hopes on a structured algorithm called ASPA, which weaves together computer models, human cell data, and exposure science into a single, traceable judgment. The deeper question this moment raises is not merely technical but civilizational: whether human
