'Smart' cephalopods trade off genome evolution for prolific RNA editing
April 6, 2017
Octopus, squid and cuttlefish are famous for engaging in complex behavior, from unlocking an aquarium tank and escaping to instantaneous skin camouflage to hide from predators. A new study suggests their evolutionary path to neural sophistication includes a novel mechanism: prolific RNA editing at the expense of evolution in their genomic DNA.
