Honeybees Seem To Understand the Notion of Zero, Study Finds (sci-news.com) 154

A new study published in the journal Science finds honeybees are able to understand the concept of zero numerosity, joining the ranks of dolphins, parrots, and primates. Sci-News.com reports: The study authors set out to test the honeybee on its understanding, marking individual honeybees for easy identification and luring them to a specially-designed testing apparatus. The bees were trained to choose an image with the lowest number of elements in order to receive a reward of sugar solution. For example, the bees learned to choose three elements when presented with three vs. four; or two elements when presented with two vs. three. When the scientists periodically tested the bees with an image that contained no elements versus an image that had one or more, the bees understood that the set of zero was the lower number -- despite never having been exposed to an "empty set."

      Also, the concept of "0" seems very different than "none" to me.

      When I think "concept of zero" I think 10>2, since that's pretty much how the concept is taught (that it was invented/discovered and revolutionized mathmatics).

        Zero and none are not different, they are the same. Zero is the numerical notation for nothing.

        why is 10 > 2?

        Because 10 equals one ten and none ones. The revolution was assigning a symbol to a concept we all instinctively "get". Look at old Babylonian for math without a symbol for zero. They used empty spaces (nothing) to denote zero.

          You are arguing that extensionally, the two concepts are the same. However, intensionally (in the philosophical meaning of intension) the two concepts are different. The stock example is that Venus is both the morning star and the evening star.

          In Frege's terms, although the analysis is a bit different, the senses of morning star and evening star are different even though their references are identical. Here, we think of Frege's sense (Sinn) as the route to reference (Bedeutung) (see here https://en.wikipedi [wikipedia.org]

            Now map this subtlety to the test of bees reacting to zero or none elements.

            The point is the distinction between those scenarios is not testable in non-sapient beings. The interesting nuance of zero being distinct from none is a human invention, and being amazed that an animal can tell nothing is there is a crazy eventuality of overthinking it.

              Yeah, like everything, it’s with a context. Zero what? None what? And their experiment had to use a real world context. So it is arguable whether the bees “understood the concept” as if it is some piece of pure logic. Rather, their nervous system could fuzzily proceess the patterns. Just like animals won’t jump down from a height that’s too great, isn’t evidence that the animal understands the concept of gravity and acceleration and weight. It has some fuzzy processing of

      • Actually, that was a step towards zero, but very much NOT what makes zero special or important.

        Using zero as a placeholder in a positional numeric system is natural... once you have a zero. But many (like the Babylonians) used various positional placeholder strategies without having a formal concept of zero.

        Zero in contrast stands on it's own. It's a formal, numerical symbol for nothing as a concrete concept, NOT just a placeholder. It's a necessary "pivot point" for much of higher mathematics. For exam

        Say instead of abstract number of elements, it was instead competing insects for the sugar. Then they would learn to prefer the less competitive environment as indicated by fewer elements. They learn a correlation, whether positive or inverse and they go with it to the natural conclusion of none. It would be odd if these natural mechanisms *did* short out when it goes from 1 to none, and yet we are repeatedly surprised to find that nature doesn't blow up at the complete lack of something.

        It's amazing because even humans living in Rome thousands of years ago created a way to write numbers but no way to write "none".

        They had a way to write nothing: by writing nothing.

        The Romans were pragmatists. This saves paper. Imagine the cost of inscribing "zero Bugblatter Beasts" on every urn, vase, and ceramic dufflebag?

        Turns out, some nebbish recruit did invent zero, but the squadron leader spotted the unfamiliar symbol one day and then he said "what the fuck is this?" and somebody said "it means we didn't get any X in our rations this month" and then the squadron leader's veins bulged out of his neck while he barked "who's the jackass wasting a perfectly good resource to record what he didn't get?" and then the jackass had to run 100 laps around the Colosseum draped with a heavy marble placard reading "lion food / reward offered"—this while the people inside were cheering the lions (more than once he panted out excitedly "look, an elephant!" pointing at some unlikely bush when people got too close for comfort, while summoning yet another painful micro-sprint, and through this device he did avoid detection in the end).

        Never made that mistake again. Not ever. Neither did anyone else, which, of course, also means that no-one was foolish enough to write a line itemizing the empty set of damn fools (many of whom invented zero, but knew better than to write it down).

      • The way to write none was a dash, or "none" (with a long o, derived from nonus).
        How do you come to the stupid idea they had no way to write "none"?

    • Well, no. Bees can see that they've already visited a flower; the visitation itself marks the flower so they don't visit it again too soon—just because we can't see those traces doesn't mean they can't. Besides, flowers don't get 'empty' quite like that.

      Understanding none is an interesting thing; it wasn't part of our system of mathematics for a long time (though it's incredibly likely people understood 'none' before it was codified into our written math) and so that makes it interesting to us.

      Considering that insects don't have the same kind of image processing or, indeed, even the same kind of eyes, I find this far more likely than they are counting elements. It is far more likely that a bee is being trained to go where there is less overall of whatever color it is the "element" is and gravitating that way. Or, and this now strikes me as being even more likely, they are going where there is more of the background. A human can look at an image and with our image processing, break it down into elements and count them. Our brains do this in the background and it might not even strike us that the image with fewer elements has more background because that's not how our brains work. It is how our brains work so strongly that it is also appearing as a bias in the way these results are being interpreted. But from a color, shade, or pixel perspective, it can be equally said that the image with fewer "elements" on it also has more background.

      I must say I find it frustrating the article has no reference to what the images were of or what the "elements" were that the bees were supposedly counting.

        That would still count as zero recognition. If it's going after more of the background. Background is a concept in itself. It needs something in the foreground to define it. Else the bees would hover toward any similar color at various distances in the general environment.

        But zero means no foreground color. Nothing to define the background. So normally the bee should be confused or gravitate toward the single "option". If they trained the bee with zero, then that's leaves it kind of open. But they didn't. They trained it with two colors where one had less. There was always two options with both colors. Then the bee recognized zero which it was never trained for... thus it was already knowledge it had.

      Did they repeat the experiment but instead of rewarding the bee when it selected the image with fewer elements, instead they rewarded the bee when it selected the image with more elements (including the occasional introduction of zero)?

    Their communication system alone is amazing. Their mental mapping when flying between locations is based on the direction of the sun, but they automatically adjust for how the sun will move (even at night or when it's otherwise not visible), in a manner that adjusts for latitude and the passing of the seasons. In the hive, they waggle dance to indicate the direction and distance to a resource (the static charges they build up can be perceived by nearby bees when they waggle). Moving straight up means "in the direction of the sun" - not "the direction of the sun when I last set out", but the current direction of the sun. Every second spent on the waggle before looping back to the start represents a kilometer of distance. A waggle dance is usually enough to bring another bee to within a couple hundred meters of a target, wherein they start searching visually. Bees don't blindly listen to waggle dances; if they're having good luck on their own, they're unlikely to listen to it, only bees that have been having trouble finding resources tend to follow them. If a bee had a *bad* experience with the location being danced to - found no resources, found a dead bee, etc - there's a "NO" buzz frequency (380Hz) which they can do. The more impressed a bee is with their location, the more vigorously they waggle dance, while the more opposed a bee is to a location, the more it does its "NO" buzz; they can even end up getting into physical fights over the issue. Advocates of different locations can also get into fights with each other.

    It's easy to think of individual bees as mindless drones as part of a "greater whole", but they really aren't; they're impressive even individually. In addition to solar navigation, they also have landmark navigation, visual navigation to small targets, and they learn what sort of things pay good rewards (which as this study shows, can involve significant reasoning). Contrary to the popular image, the queen doesn't "give direction"; she's not a "leader". She just "smells nice", and other bees want to be near her. But beyond that, each bee is an individual.

    They're fastidiously clean. They not only will remove debris and any dead bees from a hive, but they're adamant about not defecating in the hive. Honeybees will literally hold it until they die if they can't leave (e.g. in the winter due to weather) rather than foul their own hive. And maintaining the hive is a constant struggle because there's an endless list of pests and predators that want to eat either the bees, their larva, or the honey; a hive is such a tempting resource.

    Preserving the honey is of course quite the task, and bees have specific climate requirements in general. They do amazing job at managing the internal climate. Some bees will act like air conditioners, fanning with their wings to create airflow through certain areas. They'll add or remove propolis to the hive to adjust how "weathertight" it is, to get the right amount of airflow without letting in pests. In the winter, they cluster together for warmth in the "winter cluster", which slowly migrates across the comb, eating their honey stores as they go; their collective body heat keeps them from freezing, and they minimize their surface area by clustering together. Some (non-European) honeybees have taken this even further - made famous by The Oatmeal, Japanese honeybees fight off attacks from otherwise impervious Japanese giant hornets (aka real-life Tracker Jackers) by clustering around them and raising their body temperature to the point that they survive but the hornets effectively die of heat stroke.

      Son of a beekeeper here. All correct! Also, they have fairly intelligent swarming behaviour. When times are "economically" good, the sexless worker bees charged with feeding the queen will begin feeding certain larvae the special queen food, so these larvae - instead of becoming sexless workers - become queens. One of the new queens will then take part of the swarm with her (sometimes it will be the old queen btw). Individual bees decide on joining or not joining the outgoing swarm. We know they have a decision mechanism involving criteria - we simply don't understand the mechanism yet. Bees are fascinating.

      • This is not entirely accurate. Swarms always contain the old queen; the new queen stays put. This is because the swarming event actually takes place shortly before the new queen(s) emerge -- the old queen leaves so there is no fight with the new queen.

      Actually when the winter time starts, the queen is breeding special warm up bees (and most of the remaining stock dies), usually about 50 or so bees that have very short wings but much bugger muscles than the ordinary workers. So they produce a considerable amount of warmth.

    Sure, they understand '0', but do they understand what happens when you put a '1' or a '2' in front of it?
    I bet they don't.

    • What makes you think that bees understand decimal? Humans have 10 digits on their hands and feet, so decimal was pretty obvious. Bees would probably use base 6.
    • Why is that relevant? You are describing two very different mathematical concepts. You can do mathematics just fine without ever counting in a decimal notation. Maybe bees use roman numerals.

      • Maybe bees use roman numerals.
        It is actually not very easy to calculate in roman numbers. Precisely because they don't use positions to indicate value and have no zero.
        Play with a roman abacus and you understand.

        • Oh I know, but it was possible. Heck to be honest it's hard enough to count in roman numerals :)

          • Yeah, it is possible, but calculations like multiplication or division were usually done by math geniuses in their mind.

            I guess if you simply 'grasp' two numbers like vii and viii you simply add them in your mind, too, and then rewrite them as xv.

    Maybe they're not counting dots, but white space area? More white space area is better, no concept of 0 required.
    That would be fact similar to how human babies learn count. At an early stage in development they only notice/care about differences in surface area. Show them 2 objects with a 50% surface area each and 1 object with a 100% surface area and they will regard them as equal. Only later on human babies distinguish between the 2 situations.

      I know this is against Slashdot policy, but I did take a look at the original article in Science, and the training images had clearly different sized items in them, with the total area being about the same, so your area theory does not quite hold.

    Even in the case of zero the bee is still being shown a picture. In the bee's brain that might count as a "something" where this pure "something" is more attractive than that dirty "something" when it is collecting nectar. It might not be anything more than that.

    We took the concept of "nothing" and made a TV show about it [wikipedia.org].

  • Of course animals understand that no stuff is less than any amount of stuff. No lions is less lions than 1 or 2 lions.

    Zero is a symbolic representation. The innovation is assigning a symbol.

  • Are any known examples of creatures who *can* count, but who *don't* understand zero? In other words, creatures who can be trained to pick the image with the smaller number of elements, but who fail to recognize that an empty image contains fewer elements than an image that is not empty?

    That would actually be a more interesting result (I guess). I'm having a hard time getting my ahead around why this is an important question. I know that *written* systems for counting did not always use a symbol for zero

  • Do honey bees understand?
    slime mold can solve a maze , but I would not impart to it the ability to 'understand' that it is solving a problem.
    Honey bees recognize quantity , but that seems a vast a difference between that and understanding that nothing is a quantity or even recognizing quantity as a property.

    Do computers 'understand' the programs we write? certainly I could program some drones to perform the same task , would a person then claim the computer 'understands' quantity?
