A century after Hans Spemann and Hilde Mangold revealed that a tiny cluster of embryonic cells could instruct an entire body to organize itself, researchers in Jena have found that this same capacity exists in comb jellies — animals whose lineage diverged from our own some 700 million years ago. By transplanting embryonic tissue across species boundaries, the team demonstrated that the body-patterning 'organizer' is not a vertebrate invention but an ancient inheritance, present near the very origin of animal life. What once appeared to be a discovery about frogs and salamanders turns out to be
