Jumping spiders are very cute though, and can dance - so I anticipate them being very friendly.

I wouldn't consider anything with that kind of dinner etiquette to be friendly if scaled up -- humans included.

Bianca? Portia? (minor spoiler to the books)

The OP refers specifically to the Portia genus. ; )

I just finished reading Children of Time and was indeed imagining that he was looking at earlier research on this subject, because the way he describes the spiders' initial thinking skills quite echos the article. It was very fun to read from that perspective!

wonderwonder• 2 years ago

loved the first 2 books, could not get through the 3rd

codeulike• 2 years ago

Children of Time by Adrian Tchaikovsky is probably the best sci-fi I've read in the last 10 years. Its won the Arthur C Clarke award and recently the series (the other two books in the series are also great) won a Hugo

nemo• 2 years ago

Anyone who's watched jumpers hunt a while can see they're really clever little spiders. Always love finding them outside, they're little muppet spiders.

jcims• 2 years ago

Next time you see a jumping spider, interact with it. Try to coax it to you with slow repetitive movements. Get close to it. Tap and wiggle your fingers gently. You'll likely find that they come to you. They seem to be curious on a different level than any other spider that I've interacted with (which are all garden-variety spiders in north america). They do tend to freak out if you try to take their picture with a multi-lens phone camera...presumably because it looks like a set of robot spider eyes looking at them.

nomel3• 2 years ago

They're one of the only insects that show hunting behavior, as in pattern recognition and path planning [1], with brains so large that their esophagus has to go through it, to fit, with one of the largest brain to body rations of any animal. And, they dance [2]!

Easily my favorite little critter.

They're one of the only insects

They're not insects at all. They're spiders.

Edit: Here's an evolutionary tree: https://en.wikipedia.org/wiki/Arthropod#Evolutionary_history.... Insects are a group under "Hexapods", and are more closely related to crabs, lobsters, shrimp, centipedes, and millipedes (none of which are insects) than they are to spiders, which are under "Chelicerates".

JohnMakin2• 2 years ago

I think the scientific consensus for cognition and brain size has been for a long time that the size matters much less than we previously thought. For instance, ravens/crows show remarkable problem solving skills and intelligence on par with much larger animals and their brains are extremely small.

Given how much meat we as a society consume, and how we treat animals generally, it makes sense that we'd collectively accept and yearn for a narrative that animals are dumb. I think science is steadily showing that this is not really the case.

aulin2• 2 years ago

Anyone who's ever interacted with any kind of animal knows how they are intelligent.

The lack of science on this matter is not the reason we still consume meat and more science won't change anything.

We've always found ways to justify/accept our need for meat and wel'll continue doing this as long as science doesn't find an equally nutritious alternative that can be produced at scale.

rickydroll2• 2 years ago

Anyone who's ever interacted with any kind of animal knows how they are intelligent.

Anyone who's ever had backyard chickens knows they are not intelligent. Nature gave them a brain to keep the spinal cord from fraying.

JohnMakin2• 2 years ago

I’m not making any kind of statement as to why we consume meat or whether we should, just making an observation

adriand• 2 years ago

I forget who said this or exactly what they said, but someone has pointed out that the more research humans conduct the more we find that animals and even plants are more complex, more intelligent and more sophisticated than we thought. It is worth keeping this in mind the next time someone tells you a small creature (perhaps a crustacean) cannot feel or think or do something that would mean we ought to be less cruel towards them.

ChatGTP4• 2 years ago

In my opinion, many ancient cultures have known this for a long time. Of course the universe eats itself, everything seems to eat everything, that's natural, but having respect for this process is what I think we've lost.

gingerrr• 2 years ago

That's so sad. I'm pretty militantly anti-spider but jumping spiders, despite seeming like they were sent from hell to terrify us, are just little furry big-eyed arthro-bros

Fezzik2• 2 years ago

I take the opposite approach - any spider I see inside, even Black Widows, I carry outside in a cup. At least they then have a chance. And Widows will do their level best to nest somewhere far out-of-site and never bother you. I also encourage my neighbors to not sterilize around their houses with industrial bug spray because spiders and bugs are 99,999/100,000, nothing but beneficial.

TaylorAlexander2• 2 years ago

I think you are trying to come off as like, cute or funny or ironic or something. But I think this attitude is impoverished. Unless you live in a place that has spiders which are particularly dangerous to humans or pets, most spiders are just another little bug that has no interest in harming you.

Over the last ten years I went from smashing every bug I saw in my house to taking a moment to carefully scoop it up with paper or a cup and then take it outside. Most bugs (at least in my area) are safe to handle. Instead of seeing them as a threat to be destroyed, I recognize that they are innocent creatures that have no desire to mess with me, and I can serve as a steward to move them somewhere more acceptable.

There are some exceptions - pest creatures which nest in your walls or go after your food which must be exterminated to ensure a safe living environment for your home - but most often I just find little bugs trying to do their own thing, and I take a moment to provide them a little care so we don't get in each other's way.

I think this mindset helps me be more respectful of all living creatures, rather than presuming I have the right to kill those which I dislike.

I_am_tiberius• 2 years ago

That's horrible. When I see a spider, I let it crawl on a piece of paper and move it outside.

dleeftink3• 2 years ago

Exposure therapy can help squashing irrational fears, which is what I would suggest in the case of small creatures triggering a fear response.

timeon• 2 years ago

Why?

secretsatan• 2 years ago

I learnt to control my phobia over time, luckily I live somewhere where there's nothing dangerous or large, so I can leave them be.

I used to have a particular fear of jumping spiders, I blame the film "Arachnaphobia", I don't know why I agreed to see it, I was petrified the whole way through. I can handle it now, I made a point of trying more media that had spiders in them, from b movies to documentaries to photos.

But I don't think I could handle any of the bigger ones in the wild still, like tarantulas, or the absolutely massive Orb spider I saw in Africa once, ugh..

rpmisms3• 2 years ago

I had a pet jumper in my first apartment. He would follow me and my wife from room to room, wave at us, and sit by the sink when he was thirsty. We gave him water and called him Steve.

nomel3• 2 years ago

There's a reasonable pet trade for them. I never had the heart to put one in a box though.

The most interesting interaction I had was watching one hunt a fly. The fly landed, and it crawled down on the side of the board the fly was on, out of sight. It emerged behind the fly, then snuck up on it, similar to how a cat does (move, pause, move, pause). Then, when it attacked, it didn't jump at the fly, but jumped up in the air where the fly would be. It grabbed onto the flys back, then rotated, so the spider landed on its back, so the flys legs would be straight up, so it couldn't try to crawl away. It bit its neck area, waited a bit, then dragged it away. Really amazing, especially considering the fly was about the same size as the spider's body.

AlexandrB2• 2 years ago

Jumping spiders have definitely helped me get over arachnophobia a bit. They're just too cute to be afraid of.

blooalien• 2 years ago

I had a similar experience with one many years ago, but with the differences that it happened on a chair, and another fly tried to save his "buddy", which I had never seen before. It was like watchin' somethin' from the Nature channel unfold right there in "real life" in front of me. Smartest little spiders I know of. Amazing little critters for sure.

distortionfield• 2 years ago

They can take down prey much larger than themselves including small crickets and worms. They’re cool little creatures.

They are fairly common in the SF Bay Area.

Not only are they cute (the have a fuzzy look about them) but they tend to eat the stuff we hate. I tend to have one or two in my back yard almost every summer.

ianstormtaylor• 2 years ago

This is really interesting research. It’s fascinating to hear about how these experiments are designed in the first place.

If anyone is interested in this topic, I highly, highly recommend the book “Ways of Being” by James Bridle. [0]

It covers such a diverse range of ideas about intelligence, including neural network–style intelligences, that I think pretty much everyone would find something of interest.

One of the takeaways is that these intelligence-seeking experiments have been poorly designed for so long, that they tend to reveal way more about the humans running the experiment than the animals being researched. And part of that is due to how uncomfortable we are with admitting that animals have completely different (not better or worse) ways of being and thinking than us.

It makes you aware of the limitations of our hierarchy-and-comparison-based concepts. For example, even a simple phrase from this article:

Although spiders can’t literally count one-two-three, the research suggests some jumping spiders have a sense of numbers roughly equivalent to that of 1-year-old humans.

The experiment doesn’t really prove that spiders can’t count, and surely if they did count it wouldn’t be by speaking out loud like we do. Saying that their faculties are equivalent to 1-year olds only really serves to diminish them. Not that I’m blaming the author, it’s just so easy to accidentally slip into these very limited ways of thinking.

The experiment doesn’t really prove that spiders can’t count

There is very easy to prove spiders can count. They can tell bigger object from smaller, so they have some concept of measure and comparison. They can tell 10 is bigger than 2 and so on.

The rest is only how precisely they can count.

hhthrowaway1230• 2 years ago

I always feel like these papers are excuses. Like: Whoops, we found out they are intelligent, while what really happend is that we over estimated our own intelligence and downplayed the lifeforms we can't understand.

dinkleberg• 2 years ago

One of the craziest things to me when looking at a jumping spider is the unbelievable size and mass difference between us. An 80kg person is ~6,000,000x heavier than the average jumping spider. Whereas a blue whale is only like 2,000-3,000x heavier than that 80kg person (if I'm doing my math right).

They are obviously tiny, but I wouldn't have imagined what titans we must be from their perspective.

tsimionescu3• 2 years ago

A thought I've sometimes had is that if we had evolved to be as tiny as something like these spiders, but still at our current level of intelligence and society, chimps or elephants or whales would still be almost insurmountable threats to us even with today's level of technology.

It'd take entire nations years of effort to build a gun or rocket that could even hurt something that much bigger than us.

huppeldepup• 2 years ago

Which is why animals at that scale develop techniques of very rapid flight instead of brute fight. That and poison. We would probably pour the resources into genetic engineering and biological warfare.

Kinrany• 2 years ago

Not clear, we might have ended up building industrial machines of roughly the same size. Elephants are soft compared to metal no matter how tiny the driver.

sph8• 2 years ago

I wonder if anyone has calculated a range of body sizes which maximise intelligence and the ability to exploit resources of their planet.

Could a spider-sized human intelligence build a rocket to go to the moon? Would it have been easier to develop our civilization if we had been as large as a whale?

Maybe the universe is teeming with life a little too large or too small to build an ultra-technologic culture, or space travel. Imagine how long it would have taken us just to explore the Earth if we had been spider-sized, with spider legs and spider eyes.

gaiagraphia• 2 years ago

They also could provide insurmountable opportunity. You'd have a huge advantage against enemies if you could develop some kind of mutualism with the beasts of nature.

Imagine living on top of an elephant. I guess you would attend to its skin and health, in exchange for a great defensive position, free transport, the potential to live off dying cells and moisture, etc.

Fast forward a very long time, and you might have humans controlling all the animals of the wild, which would have developed their own ways of survival, territory and rivalries. Animals which lack this 'army' of humans tending to them would die out. Wouldn't be so different to now...

odyssey72• 2 years ago

Animal intelligence will continue to be surprising for as long as animal exploitation remains mainstream.

noman-land2• 2 years ago

The more I learn about various living beings around us, the more I'm convinced that they are all unique, individual people, with unique opinions and desires. They have unique DNA and unique personalities.

If you've ever spent an extended period of time with any animal, you know that they all have different personalities and opinions that differ from other animals of the same species, eerily similar to humans. They truly are different people. Some are shy. Some are gregarious. Some are brave. Some are lazy. Some are dumb. Some are mean. They're all different.

I don't really know how to reconcile this feeling and I'm very much an omnivore but the thought is inescapable to me.

In order for you to keep living, something with a unique personality, opinions, and desires has to die. And that includes plants.

hombre_fatal• 2 years ago

Is that moral justification for eating or stepping on the sentient being over the plant, just because they’re both alive?

noman-land2• 2 years ago

If anything it's moral justification for not doing that. I was pointing out how I kill living things in order to remain alive, even though I think they are unique individual people and it's troubling and confusing to me (because in order to live, another thing has to die).

wolverine8764• 2 years ago

Thinking seriously about it:

Of course you can try to minimize the sentience of what you eat - wheat < ants < pigs < people - which may be better than nothing, but I'm sure you've thought of that.

I heard of a small religion that eats only nuts and fruits, with the belief that the plants want them eaten - they evolved to make the nuts and fruits desireable in order to spread the plant's seeds. It's arguably still exploitation: The plants evolved that way because it is the least bad option among predators.

odyssey72• 2 years ago

If panpsychism is true, then even the molecules our bodies cleave apart during digestion could be sentient.

ChatGTP4• 2 years ago

Alan Watts used to say, it's ok to eat plants and animals, as long as when you cook them, you make something beautiful out of them to respect their sacrifice. It's the least you can do.

I feel there is some truth to this. Eventually, your body will be consumed by insects.

OK, so how can we analyze whether results are made up, partially made up, credible, etc.?

I'm sure people would hate to fund that too, or have their lab or university associated with it. How could they avoid it?

Actually, I wish we allocated more money to biology and understanding the living rather than bullshit technology that literally is destroying the world (which is an observable fact).

These results could well be made up.

Sure, but in terms of priority about "made up" results, I would first look at all those damn startups that literally make up results in order to get VC money.

The first time I ran into one of these cute little jumping spiders was in a backyard while I was reading a book. I felt something on my chair and moved and I saw something jump across to the small table next to me. I noticed that it was a spider. I didn't know spiders could jump like that. I was very surprised when it turned around and looked at me. Scrutinizing me. It literally was moving its head looking at me trying to figure out what had disturbed it. After that my girlfriend at the time joked that he was my little friend.

I had a pet jumping spider that came to me one day. She was magical. She used to make artistic scribbles in the (sometimes) foggy glass of her terrarium.

shoo• 2 years ago

previously: science fiction author Peter Watts' 2009 post musing about spider intelligence vs Turing machines:

https://rifters.com/real/2009/01/iterating-towards-bethlehem...

Here's the thumbnail sketch: we have here a spider who eats other spiders, who changes her foraging strategy on the fly, who resorts to trial and error techniques to lure prey into range. She will brave a full frontal assault against prey carrying an egg sac, but sneak up upon an unencumbered target of the same species. Many insects and arachnids are known for fairly complex behaviors (bumblebees are the proletarian's archetype; Sphex wasps are the cool grad-school example), but those behaviors are hardwired and inflexible. Portia here is not so rote: Portia improvises.
But it's not just this flexible behavioral repertoire that's so amazing. It's not the fact that somehow, this dumb little spider with its crude compound optics has visual acuity to rival a cat's (even though a cat's got orders of magnitude more neurons in one retina than our spider has in her whole damn head). It's not even the fact that this little beast can figure out a maze which entails recognizing prey, then figuring out an approach path along which that prey is not visible (i.e., the spider can't just keep her eyes on the ball: she has to develop and remember a search image), then follow her best-laid plans by memory including recognizing when she's made a wrong turn and retracing her steps, all the while out of sight of her target. No, the really amazing thing is how she does all this with a measly 600,000 neurons— how she pulls off cognitive feats that would challenge a mammal with seventy million or more.
She does it like a Turing Machine, one laborious step at a time. She does it like a Sinclair ZX-80: running one part of the system then another, because she doesn't have the circuitry to run both at once. She does it all sequentially, by timesharing.

Blindsight. One of the most interesting sci-fi stories I found impossible to get into and enjoy due to the author's dense and obtuse prose. I have a squirrel brain, so maybe it's just me.

Jumping spiders are quite common here in Singapore, and occasionally one will wander across my monitor while I'm working.
