Findings (2)
finding
- Ectopic eyes induced by ion channel misexpression; if few cells injected, they recruit unmanipulated neighbors to produce normal-sized eyes—collective recruitment competency.
- In tadpoles with disrupted bioelectric signaling: different reagents produce 0-100% conversion rates in populations, but individual animals are entirely converted or entirely normal—collective decision-making phenomenon.
