Octopuses Are Rewriting Their Own Genetic Code — And It’s Making Them Smarter Than Evolution Intended 🐙🧬
Octopuses have long captivated human imagination. They solve puzzles, escape aquariums, wield tools, and even recognize individual people — feats of intelligence rarely seen outside of primates. But how did these soft-bodied invertebrates, with brains so different from ours, become so astonishingly clever?
The answer, it turns out, may be that octopuses are literally reprogramming their own brains in real time.
Recent research has revealed that octopuses and their close relatives (squid and cuttlefish, collectively known as coleoid cephalopods) engage in a massive amount of RNA editing — a process by which genetic instructions are rewritten on the fly to produce proteins that aren’t encoded in their DNA. Unlike most animals, which treat RNA editing as a rare glitch-correction system, oct...
