finding

Brief chloride ion channel activator drug exposure converts normal melanocytes to melanoma-like phenotype in an all-or-none population-level fashion (Blackiston et al. 2011, Lobikin et al. 2015)
supports
Reveals that melanocytes across the whole animal make a coordinated, stochastic decision to convert or remain normal.

Melanoma conversion is all-or-none at animal level despite population variationfinding0.776
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.
