> Let me see if I follow: once the snake population has the warning coloration, and predators know not to eat them, then individual snakes being successful at eating poisonous newts is unrelated to the snakes living long enough to pass their genes (i. e. being successful in terms of natural selection). So a snake which has the right colors will be successful, regardless of its diet.
Sort of. Whether the snake is poisonous is unrelated to its success, because it dies upon being eaten whether there are consequences to its predator or not. (The article takes some pains to show that this is untrue of the newts, but not the snakes.)
However,

This does not reflect a good understanding. Success means having more children, not having any children.

I never said "any children", so your remark doesn't reflect a good understanding of what I wrote.
Try not being pedantic for pedantry's sake, and engage with a question asked in good faith without playing games of one-upmanship.
You said that living long enough to reproduce constituted Darwinian success. That idea is (1) extremely common, and (2) dead wrong.
