    DOI: More than compounds have been found in poison frogs, but fewer than 70 are well understood, says Tarvin. What's more, it turns out that the frogs evolutionarily stumbled across this resistance on at least three separate occasions, a testament to that mutation's usefulness.

    Acetylcholine and epibatidine bind to the nerve receptor at the same place, so if mutations changed the receptor's shape too much, acetylcholine wouldn't be able to do its crucial day-to-day job. Protein mutagenesis experiments implicate a shared binding side for the enantiomers in the inner pore cavity of NaV. Phyllobates terribilis.
