- Tadpoles with scrambled craniofacial organ positions (Picasso tadpoles) develop into largely normal frogs.finding0.880When eyes, nostrils, and jaws were mispositioned, they moved via novel trajectories and stopped upon reaching correct frog face positions, demonstrating anatomical homeostasis.
- Xenopus tadpoles with scrambled craniofacial structures rearrange to form normal frog faces.finding0.864From Vandenberg et al. 2012; demonstrates anatomical homeostasis beyond hardwired movements.
- Evidence for multi-scale competency: morphological goal-seeking independent of initial conditions
- Evidence of morphogenetic problem-solving and anatomical homeostasis across serious perturbations; demonstrates collective intelligence in development.
- Empirical example of regulative development: when craniofacial organs are positioned abnormally, they reposition via non-natural paths until correct frog face is achieved.
- Tadpoles with displaced craniofacial organs can still develop normal face through organ movement.finding0.818From Vandenberg et al. (2012) and Pinet et al. (2019), reveals regulative morphogenesis.
- Cited as evidence for anatomical goal-directedness regardless of starting configuration
- Embryological finding showing the specific mechanism — insertion of new local symmetries — by which wholeness is preserved and extended in biological development
