Bees May Understand Zero, a Concept That Took Humans Millennia to Grasp

If the finding is true, they’d be the first invertebrates to join an elite club that includes primates, dolphins and parrots

As a mathematical concept, the idea of zero is relatively new in human society—and indisputably revolutionary. It’s allowed humans to develop algebra, calculus and Cartesian coordinates; questions about its properties continue to incite mathematical debate today. So it may sound unlikely that bees—complex and community-based insects to be sure, but insects nonetheless—seem to have mastered their own numerical concept of nothingness.

Despite their sesame-seed-sized brains, honey bees have proven themselves the prodigies of the insect world. Researcher has found that they can count up to about four, distinguish abstract patterns, and communicate locations with other bees. Now, Australian scientists have found what may be their most impressive cognitive ability yet: “zero processing,” or the ability to conceptualize nothingness as a numerical value that can be compared with more tangible quantities like one and two.

While seemingly intuitive, the ability to understand zero is actually quite rare across species—and unheard of in invertebrates. In a press release, the authors of a paper published June 8 in the journal Science called species with this ability an “elite club” that consists of species we generally consider quite intelligent, including primates, dolphins and parrots. Even humans haven’t always been in that club: The concept of zero first appeared in India around 458 A.D, and didn’t enter the West until 1200, when Italian mathematician Fibonacci brought it and a host of other Arabic numerals over with him.

But animal cognition researchers at the RMIT University of Melbourne, Monash University in Clayton, Australia and Toulouse University in France had a hunch that honey bees might just be one of the few species able to grasp the concept. Despite the fact that they have fewer than one million neurons in their brain—compared to 86,000 million in a human brain—the team recognized their cognitive potential.

1. Uhhh, I don't think humans lacked the concept of zero

for a long time. Their numbers didn't have a specific digit to represent zero, but that is not remotely the same as not having the concept.

2. bumblebees solve AI problems in fewer iterations of training data

than modern supercomputers.

Bumblebees will train the entire hive (workers) on the "relative best" route to fly to gather nectar (the traveling salesman problem). This isn't the absolute optimum route but a "good route" that conserves energy and time.

AI algorithms running similar problem sets using tools like TensorFlow typically take more iterations of the training data to solve the same problem (but much faster of course).

3. It's long been known that some bees are very clever and intelligent.

Take, for example, the spelling bee. Or the quilting bee...
