- Salamander limbs regenerate missing parts precisely and stop when target morphology is reached, demonstrating goal-directed morphogenesis.
- Biological example of anatomical homeostasis: amputated limb regrows and knows when to stop, demonstrating error-minimization and setpoint-seeking behavior.
- Indicates that prior experience can alter morphogenetic capacity.

- Frog legs regenerated after specific induction did not form a paddle with interdigital apoptosis but grew digits from a central core, reaching correct final form via atypical intermediate states.
- Planarians cut into pieces regenerate precisely what is missing and re-scale tissue to form complete worms.
