Ectopic Eye Formation via Bioelectric Signaling

Misexpression of potassium channels in frog tadpole gut or tail induces formation of complete, functional eyes in ectopic locations; demonstrates that morphogenetic modules can be triggered by high-level bioelectric signals without specifying molecular details.

Claims (1)

claim

Morphogenesis is the behavior of a collective intelligence of cells solving problems across multiple scales.
supports
Levin's main interpretive reframing: rejects purely emergentist/mechanistic views of development in favor of treating morphogenesis as cybernetic, goal-directed problem-solving by cellular swarms.
