Isn't more that that their RNA is constantly being rewritten than the cephalopods themselves doing writing? What force is responsible for choosing the new RNA?

I would not say it is the animals themselves doing the writing as a force of will, sentience, or consciousness, which is what the headline implies.
The article itself says:
> Their RNA is extensively rewritten, particularly the codes for proteins found in the animals' neurons.
Tune in next week for more headline pet peeves
- dluan 10y agoThat's a valid question, for which you shouldn't be downvoted, but you should know that it's not anything about it being a force of will by the animals, more that it's a new behavior of how the animal cells are diverse. In other words, maybe the animal is in higher temperatures that trigger a gene to begin executing this particular 'circuit', which causes proteins to form that make slightly more responsive nerve cell ion channels. Where previously we assumed that variation was spread mainly through genes in DNA, this headline shows that there are other ways beyond just DNA-> RNA-> protein. I may have totally borked this attempted analogy, so hope that helps.
