The intelligence of cephalopods — a category of marine animals that features octopuses, squid and cuttlefish — has lengthy been a topic of fascination amongst biologists. Not like most invertebrates, these animals possess outstanding recollections; use instruments to resolve issues; excel at camouflage; react with curiosity, boredom and even playful malevolence to their environment; and might dream, if the ripples of colours that flash throughout their pores and skin as they sleep are any indication.

Now, this new research, revealed Dec. 5, 2022 within the journal Present Biology, means that key components of the components for superior intelligence, on Earth no less than, stay the identical.

“Our conclusions have been shocking as a result of loads of what we learn about nervous system growth in vertebrates has lengthy been considered particular to that lineage,” research senior writer Kristen Koenig, a molecular biologist at Harvard College, stated in a assertion. “By observing the truth that the method could be very related, what it instructed to us is that these two [lineages] independently advanced very giant nervous methods utilizing the identical mechanisms to construct them.”
