Squid and octopus can edit and direct their own brain genes
New Scientist
Unlike other animals, cephalopods – the family that includes octopuses, squid and cuttlefish – do not obey the commands of their DNA to the letter. Instead, they ... and one cuttlefish. The mechanics of cephalopod RNA editing are still being investigated.

How the Octopus Broke the Rules and Got So Smart
WCAI
There's a textbook version of evolution that goes something like this: random changes to an individual's DNA are inherited by its offspring. The worst changes are weeded out by natural selection, and the process goes on. Unless you're an octopus or a ...

Evolutionary genetics Fantastic beasts — cephalopod RNA recoding
Nature.com
Four species of coleoid cephalopod (two species of octopus, a squid and a cuttlefish) were compared to more primitive species (a nautiloid and a mollusc). For the squid, octopus and cuttlefish species, 80,000–130,000 A-to-I editing events were obtained.
