Octopus and Squid Evolution Is Weird

“This shows that high levels of RNA editing is not generally a molluscan thing; it’s an invention of the coleoid cephalopods,” said co-lead researcher, Joshua Rosenthal of the US Marine Biological Laboratory. The researchers analysed hundreds of thousands of RNA recording sites in these animals, who belong to the coleoid subclass of cephalopods. As the next step, the team will be developing genetic models of cephalopods so they can trace how and when this RNA editing kicks in.
