Octopuses' Ribosomes Hint at a Convergent Route to Smarter Brains
Researchers propose that octopuses may have boosted their nervous system complexity through a unique H88 break in ribosomal RNA that increases the accuracy of protein synthesis, reducing misfolded proteins in long-lived neurons; experiments even implementing a similar ribosomal change in E. coli support the idea that this tweak enhances protein folding, highlighting a convergent evolutionary path to smarter brains driven by challenging environments.
