Octopuses are typically antisocial, short-lived, and prone to dying after mating for the first time, which makes them very different to other intelligent animals, but pretty similar to you.
How did octopuses (not "octopi") get so smart? They're not sociable or long-lived. But they do have 1 thing in common w humans: free prehensile limbs, allowing IQ to be not pure cogitation but actionable.
We're increasingly aware that octopuses are smart. But WHY did they become smart? Here's one possible explanation
Octopuses are very intelligent, but they’re also unsociable, short-lived, and prone to cannibalizing their peers. That makes them unique in the animal kingdom, according to scientists who have evidently never met any grad students
Why did octopuses become so insanely smart? Marine biologists have puzzled over this for years. One new theory: Because they lost their shells. Or: Vulnerablility makes you smart. You *need* it. My gloss, but it’s the tl;dr of this terrific piece
Smart animals tend to be sociable and long-lived. Octopus are among the smartest – but they're not sociable or long-lived. Why did they evolve their great intelligence? According to a recent paper, it's to compensate for losing their shells.
(who has me blocked) has seriously misrepresented animal intelligence in such a way that I'm back on Twitter just to rage. This idea that sociality is a primary driver in animal intelligence is an oft-repeated fallacy that has no basis.

For intelligent animals, cephalopods are weird, in that they live short, solitary lives. But these notable traits might all be linked to a fourth, writes —the ancestors of octopuses lost their shells.

Octopuses (and other cephalopods) are unusually smart for how short their lives are. How did they become smart?
"cephalopods aren’t just weirdly intelligent; they’re also very weird for intelligent animals." - is very, very good! On literally any topic - slime, octopi, microbiome ...
A new hypothesis suggests that their vaunted intelligence and short-lived, solitary nature are all linked to a fourth trait
The horror story of evolution and intelligence... #octopus #predators #intelligence

I am compelled to point out that classic studies of octopus intelligence are plagued by methodological problems. A better study found that 3 octopuses failed to learn a reversal task; the 4th passed, but did not score as highly as a bumblebee or cockroach.
