Caption: This illustration is a montage of photographs, taken from Figure 4 of 'Testing Turing's Theory of Morphogenesis in Chemical Cells,' depicting the evolution of physical morphogenesis from an initial homogeneous state (upper left, same volume and color) through a chemically heterogeneous state (center, same volume but different colors) and into a chemo-physical heterogeneous state (lower right, different volumes and colors). This cellular differentiation takes place exactly as Alan Turing predicted it would in his 1952 paper, 'The Chemical Basis of Morphogenesis.'
