Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire.

Not so with genetic instructions for making proteins. Even a small change can prevent a protein from doing its job properly, with possibly deadly consequences. Only occasionally is a change beneficial. It seems wisest to preserve genetic instructions as they are written. Unless you’re an octopus.

Octopuses are like aliens living among us — they do a lot of things differently from land animals, or even other sea creatures. Their flexible tentacles taste what they touch and have minds of their own. Octopuses’ eyes are color-blind, but their skin can detect light on its own (SN: 6/27/15, p. 10). They are masters of disguise, changing color and skin textures to blend into their surroundings or scare off rivals. And to a greater extent than most creatures, octopuses squirt the molecular equivalent of red ink over their genetic instructions with astounding abandon, like a copy editor run amok.

These edits modify RNA, the molecule used to translate information from the genetic blueprint stored in DNA, while leaving the DNA unaltered.

Scientists don’t yet know for sure why octopuses, and other shell-less cephalopods including squid and cuttlefish, are such prolific editors. Researchers are debating whether this form of genetic editing gave cephalopods an evolutionary leg (or tentacle) up or whether the editing is just a sometimes useful accident. Scientists are also probing what consequences the RNA alterations may have under various conditions. Some evidence suggests editing may give cephalopods some of their smarts but could come at the cost of holding back evolution in their DNA (SN: 4/29/17, p. 6).
