ARTICLE TEXT:
Humans’ invention of zero was crucial for modern mathematics and science, but we’re not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.
Honey bees are known to have some numerical skills such as the capacity to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting quinine.
Once the bees had learned to consistently make the correct choice, the researchers gave them a new option: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose this option rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren’t just going for the empty picture because it was new and interesting: Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.
In further experiments, the researchers showed that bees’ understanding of zero was even more sophisticated: For example, they were able to distinguish between one and zero—a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.
thank you king
Hmm, “64%” part irks me. What if statistical error was involved?
Amazing! Thanks for sharing. :-)
I love bees, and now I respect them even more. Glad it was interesting to someone other than me!
Wait until you find out ants pass the mirror test.
One study found that three species, Myrmica rubra, Myrmica ruginodis, and Myrmica sabuleti have shown potential for self-recognition (Cammaerts and Cammaerts, 2015). When exposed to a mirror, ants of all three species marked with a blue dot would attempt to clean themselves by touching the mark. Similar results were not exhibited when ants were marked with a brown dot, which is the same color as their body. It appears that the ants used their mirror reflection to see the unusual blue dot and attempt to clean it. If true, this behavior would indicate self-recognition.
One thing I like to do with my pets when they’re young is play with them through the mirror so they can make the connection that kitty getting their neck scritched is the same kitty getting their neck scritched. There’s nothing more rewarding than the moment they look at you through the mirror, then look up at you directly and then do that little slow eye close showing that they know you are also the same person.
I didn’t even realize they could see much at all tbh. I thought most of their navigation was through smell! This is a super interesting article!
Amazing, specially considering that gorillas either fight or flee their reflection on mirrors. There are videos on YouTube, quite entertaining btw.
Interesting stuff!
Heh. I’m sure we all know a few of those non-“recent” humans that can’t seem to grasp the concept. I just hope they’re in lower numbers than expected this November. 😶
Sounds like a snarky suckjob for genociders to me
This might be hard for you to understand but there might even be zero of them left
Edit
lol, I love how controversial this comment is. The joke was that if there were “zero of them”, it wouldn’t be hard for to understand for anyone. If it’s hard for them to understand, the number of “non recent” humans wouldn’t be zero. It’s a self contradiction, a paradox, what ever. First and foremost it was a joke.
Just read the article. 64% is awfully near to 50%. Specially if the number of trials was low.
Its a 28% increase. To me, thats colloquially significant.
Now, I went to the research article. The number of trials (n) was 10. To me, this is not strong evidence. If an independent group would take upon this work and find similar results, I would very much be inclined to change my mind.
10 trials is lot of replication and more than reliable enough. Thats improbable, even for a 50:50. Honestly, I’m quite taken aback that you think 10 repetitions of the same result isn’t strong evidence and it screams that no one would ever be deemed independent enough, unless they found the results you wanted.
If bees had 2 options, by random chance they would go to any of them (i.e. no learning or concept of zero). That’s 50%. The article is based on 10 bees, and only 6.4? chose the correct answer. Ok, I am definitely not understanding this. I would need to re-read it…
Maybe this is just my hippocampus privilege, but I have a hard time imagining the concept of zero as being difficult to comprehend
