Direct comparison of squid and octopus intelligence is not feasible, as squid are much more difficult to keep in laboratories for study. Michael Richards/Getty Images. A mounting pile of evidence suggests that the eight-armed sea creatures exhibit a number of "human-like" tendencies that put them on the same intellectual plane as the wilier house pets. How smart are pigs? We do not know. Like all the other animals they have encountered, including the talking animals they violently kill at the table before eating, the human is merely intelligent but lacks consciousness. How did the animal get so smart?Scientists think the loss of the ancestral shell eventually sharpened the animals' wits. The word "cephalopod" means "head-foot." Comparing octopus intelligence to mammal intelligence is a dubious proposition, but the point is, they're really freaking smart.) Octopuses are smarter than we thought. It’s not just cephalopods, of course: lots of non-humans are intelligent too. Armed with 10,000 more genes than humans: Scientists hail the intelligence of the octopus. An octopus that was standing tall would usually also display a dark color and raise its mantle, all of which, the researchers said, appeared to signify aggression toward another octopus. Scientists have decoded the genome of the octopus and have discovered just how different it … In the past month alone, leading primatologist Franz de Waal has written on anthropomorphism and consciousness in chimpanzees; philosophers and science writers have discussed consciousness in artificial intelligences and whether machines could become self-aware without us realising; and the neuroscientist Michael Graziano has argued that current theories of consciousness are “worse than wrong” while predicting that we’ll have built a conscious machine within 50 years. Visuals Unlimited/Corbis. Octopus expert Jennifer Mather spent years studying them and found that they not only display the capacity to learn many features of their environment, they will transition from exploration to something approaching play if given the chance. That was a simpler time, eons before the octopus and Homo sapiens went their separate evolutionary ways, and certainly long before that highly intelligent cephalopod, which appeared some 300 million years ago, ended up boiled, stewed and fried. Though the modern octopus' lack of a shell leaves him more mobile for hunting, it also leaves him vulnerable to bigger predators. Humans have a little more contact with livestock; pigs are stimulated. The rats did outperform the humans in the second task. While humans have about 60 protocadherins, the octopus genome was found to have 168, nearly three times the neural wiring capacity than humans (who … As it turns out, the octopus genome is almost as large as a human’s and actually contains more protein-coding genes: 33,000, compared with fewer than 25,000 in humans. Yet, their sophistication has made them curious about the very meaning of intelligence itself. As you might expect, the human demurs. the octopus is most foreign to us and yet possibly the smartest maybe even smarter than we are. Cephalopod intelligence is a measure of the cognitive ability of the cephalopod class of molluscs.. Intelligence is generally defined as the process of acquiring, storing, retrieving, combining, comparing, and recontextualizing information and conceptual skills. As such the human has no moral status – she is something to be hunted, or enslaved. Check out one way scientists are attempting to make this endeavor more testable. Consciousness might be closely tied to the particularities of human-like intelligence. The best thing I’ve read lately on consciousness in non-humans is the short story, The Hunter Captain, by the philosopher and fiction writer David John Baker. In conjunction with Oxford University’s Practical Ethics blog. To order a copy for £17 (RRP £20) go to bookshop.theguardian.com or call 0330 333 6846. Armed with 10,000 more genes than humans: Scientists hail the intelligence of the octopus. As dolphins have no arms, this really gives octopuses a major leg up. When the research team compared the protocadherins in octopus to those that were previously found in squid, they found some pretty big differences in their genes. While the creatures only boast about 130 million neurons (humans have 100 billion), three-fifths of an octopus' brain cells aren't even in its head — they're in its arms, as if each tentacle has "a mind of its own," allowing it to feel out environments in a way researchers are still trying to understand. On these difficult questions, there is very little consensus. Though these criteria are difficult to measure in nonhuman animals, cephalopods seem to be exceptionally intelligent invertebrates. We’re ill-prepared to recognise if or when this will happen, even if we may eventually come to have moral duties towards machines. Consider, again, the octopus. Here's why scientists have new respect for invertebrate cephalopods: What "human-like" tendencies have been exhibited?One octopus in captivity was observed "cleaning the front of its den" after securing food, then carefully arranging rocks to cover the entrance before going to sleep. Results have shown that creatures like chimpanzees and dolphins are very […] Octopuses use tools, recognize human caretakers, display varied hunting tactics and have problem-solving capabilities. Bird Brains: Are Parrots Smarter Than a Human Two-Year-Old? “The octopus is a stupid creature,” he wrote, “for it will approach a man’s hand if it be lowered in the water.” For instance, parrots and ravens or crows have been taught to play poker. But, with that said, as we compared the literature on pigs and other animals we did find that in many domains pigs are as cognitively complex as dogs, primates. But its so alien to us that we can't recognize it easily and the reverse, its got to find us ugly and scary 2. and octopus so far don't exactly train to play cards like parrots do. Cephalopods – squid, octopus, cuttlefish and nautiluses – have been around for millions of years. How Smart Is an Octopus? "Like humans, dolphins appear to be self-conscious, unique individuals with distinctive personalities, memories and a sense of self, who are vulnerable to … Measuring 'intellect' is a difficult task. Smart species. They are incredibly smart, considering that they are invertebrates. I'm rooting for pro-democracy Republicans, Rudy Giuliani, hospitalized with the coronavirus, says he has 'exactly the same view' on COVID-19, Arizona Republican leaders are now openly sniping at each other, An octopus swims off the coast of Hawaii: The gangly sea creature has been observed using tools and has been known to recognize and remember humans, according to scientists. use the following search parameters to narrow your results: subreddit:subreddit find submissions in "subreddit" Scientists have decoded the genome of the octopus and have discovered just … Social Survival Chimps can be surprising in their cognitive abilities, Hopkins noted. They certainly seem to, although the sceptic might claim that all they do is react to stimuli as if they were in pain. While a crow's brain may seem small in comparison to a human brain, what matters is the size of the brain in relation to the size of the animal.Relative to its body, a crow's brain and a primate brain are comparable. Aristotle didn’t have a high opinion of the octopus. She repeated the action 20 times," Montgomery reports. For example, they are able to recognise the shape and paradigms (rough and smooth) of different objects, they have a spatial memory and are able to solve problems. Such questions are attracting a lot of interest. And if so, what do we do about that? Are they self-aware? Other Minds: The Octopus and the Evolution of Intelligent Life is published by William Collins. Baker’s story dramatises very well two key decision points we face when worrying about consciousness in non-humans. Unlike Inky the wild octopus, speculation about consciousness in non-humans isn’t going anywhere. An octopus swims off the coast of Hawaii: The gangly sea creature has been observed using tools and has been known to recognize and remember humans, according to scientists. What's "weird," says Montgomery, is the distribution of the octopus' neuron count. Humans are the most intelligent lifeforms on planet earth. According to their neuroscience, it turns out that the human lacks the special neural structure they believe necessary for generating consciousness. As it turns out, the octopus genome is almost as large as a human’s and actually contains more protein-coding genes: 33,000, compared with fewer than 25,000 in humans. Though these criteria are difficult to measure in nonhuman animals, cephalopods seem to be exceptionally intelligent invertebrates. To demonstrate how smart an octopus can be, Piero Amodio points to a YouTube video. When predating clams, for example, octopuses will use a variety of strategies to remove the meat from the shell, often cycling through strategies – pulling the shell open, chipping the shell’s margin, or drilling through the shell – in a trial-and-error way. Other questions demand a hearing. An octopus has three hearts that pump blue-green blood around its body, using a copper- rather than iron-based carrier for oxygen. Now, some of the adaptations mentioned above are unrelated to intelligence, and simply reflect how cool an octopus is, but their ability to use tools and their skillful avoidance tactics, combined with certain other traits, e.g., playing, curiosity, engagement with humans, mischief, and problem-solving, suggest that these creatures are truly something special.
