In frog embryo development, each transformation introduces new structure in the form of new asymmetrically placed local symmetries inducing new layers of differentiation without dispersing the underlying deep structure.

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Ectopic eyes formed in frog embryo tails still function; eye primordia cells succeed in forming an eye, optic nerve, and correct neural connections despite abnormal spatial context.finding0.788
• In embryological development, chemistry and cell migrations are mechanisms that do the work but are simply not the principal thing going on — the fifteen properties and their unfolding are.claim0.783
  Alexander's interpretive priority claim distinguishing mechanistic substrate from the morphogenetic principle at work
• The apparent mysteries of embryological morphogenesis may be more easily understandable when we consider that evolution from time t to t+1 is governed by strengthening centers while preserving and enhancing as much structure as possible.hypothesis0.779
  Alexander's predictive hypothesis that the principle of unfolding wholeness will provide new explanatory leverage for embryology
• Morphogenesis is not simply an emergent result of local rules but has complex, multi-scale feedback mechanisms that implement teleonomy and problem-solving.claim0.779
  Posits genuine goal-directedness in development.
• Parts created during the process of differentiation must become locally unique; otherwise the process is not a living process.claim0.770
  Necessary condition that prevents mechanical mass-production and enforces local adaptation.
• Developing Xenopus tadpoles can attain normal anatomical outcome despite starting with craniofacial organs scrambled or with wrong number of cells.finding0.769
  Evidence of morphogenetic problem-solving and anatomical homeostasis across serious perturbations; demonstrates collective intelligence in development.
• Every living process resembles, in general terms, the process which underlies the unfolding of an embryo—morphogenesis.claim0.768
  Deep structural analogy that argues living process in architecture mirrors biological differentiation and division.
• Embryogenesis of a mouse foot demonstrates harmony-seeking through emergence of strong centers, boundaries, gradients, levels of scale, contrast, local symmetries, and good shape across four developmental days.finding0.768
  Example demonstrating how latent structures in development are progressively consolidated and solidified through structure-preserving transformations.
