We suggest here that evolutionary and developmental processes differ primarily in scale. Both evolution and development are dynamical processes subject to bottom-up and top-down constraints, and both can be viewed as search processes in rugged landscapes with multiple attractors. An important aspect of regulative development and regeneration is the ability of the system to reach the same anatomical configuration from different starting points and despite perturbations – a robustness toward a specific “target morphology” as the set point of a homeostatic cycle. We propose that evolution can be viewed as a developmental process of life as a whole, and that principles of regulative development and regeneration can, therefore, be expected to be active at much larger spatio-temporal scales: the major evolutionary transitions, including endosymbiosis, multicellularity, and the emergence of social groups, can be regarded as features of a “target morphology” of organismal phylogeny that biolog
