Established: A 2026 Current Biology study reported an unusual ribosomal-RNA arrangement in octopuses that may help them produce proteins with unusual accuracy. The researchers and outside scientists connect this possibility to the demands of maintaining long-lived neurons. Uncertain: the evidence does not yet prove that this molecular feature caused octopus intelligence; correlation is still wearing the suspiciously large hat.
