Humans tend to put our own intelligence on a pedestal. Our brains can do math, employ logic, explore abstractions and think critically. But we can’t claim a monopoly on thought. Among a variety of nonhuman species known to display intelligent behavior, birds have been shown time and again to have advanced cognitive abilities. Ravens plan for the future, crows count and use tools, cockatoos open and pillage booby-trapped garbage cans, and chickadees keep track of tens of thousands of seeds cached across a landscape. Notably, birds achieve such feats with brains that look completely different from ours: They’re smaller and lack the highly organized structures that scientists associate with mammalian intelligence.

    Yes, this is cool, but imagine if you will the octopus, evolving intelligence from inside phylum mollusca, whose common ancestor with us (and all chordates) is an ancient worm.

    Their brains might as well be alien compared to chordate intelligence.

      It’s super interesting that they’re not social animals either. So much of our brainpower goes towards complex social bonds and effective cooperation, whereas octopuses generally just do not care about that stuff

        But that’s also what holds them back, because without socialization, they can’t accrue and pass on knowledge through communities or down generations. They’re incredibly intelligent, perhaps rivaling our own; but they’re perpetually stuck in the Neolithic Era, because each has to learn tool use from scratch.

          Plus they live very short lives, giving less opportunity for the accumulation of a lot of knowledge.

          Their reproduction strategy and life cycles also basically don’t allow for generational interaction: most octopuses reproduce only once, produce tens of thousands or even hundreds of thousands of offspring, and die shortly after reproduction. Then the young paralarvae drift as plankton until they grow large enough to settle wherever on the sea floor they happen to be.
