Octopus and squid evolution is officially weirder than we could have ever imagined
Just when we thought octopuses couldn’t be any weirder, it turns out that they and their cephalopod brethren evolve differently from nearly every other organism on the planet.
In a surprising twist, scientists have discovered that octopuses,
along with some squid and cuttlefish species, routinely edit their RNA
(ribonucleic acid) sequences to adapt to their environment.
This is weird because that’s really not how adaptations usually
happen in multicellular animals. When an organism changes in some
fundamental way, it typically starts with a genetic mutation – a change
to the DNA.

The findings have been published in Cell.
