Originally of my analysis profession round 15 years in the past, any suggestion {that a} bee, or any invertebrate, had a thoughts of its personal or that it may expertise the world in an intricate and multifaceted method could be met with ridicule. As Lars Chittka factors out within the opening chapters of The Thoughts of a Bee, the attribution of human feelings and experiences was seen as naivety and ignorance; anthropomorphism was a unclean phrase.
Pet homeowners eagerly ascribe feelings to their animals, however the easy mind of a bee absolutely couldn’t expertise the wealthy tapestry that’s our existence. They’re far too simplistic and robotic, proper?
Lars Chittka has been researching honeybees for the previous 30 years. The Thoughts of a Bee is a group of his analysis tales. It additionally covers the influential figures in bee analysis and supplies a historic perspective on the analysis that a lot behavioral work is constructed on right now.
Folks have lengthy been curious concerning the habits of bees. Many questions posed within the 1800s are nonetheless round. Whereas Chittka’s superbly collated and fascinating “story” doesn’t current analysis outcomes which are essentially new, to learn them offered collectively like this, I discover myself tantalized by questions I had not thought to ponder. For instance, how do bees determine who stays and who leaves when a swarm is shaped?
The World of a Bee
The e book opens by difficult you to place your self into the world of a bee.
A honeybee’s expertise of the world is so fully overseas to our personal that to grasp and analysis it’s a problem to not be underestimated. Certainly, it’s comprehensible that now we have relegated the expertise of bees to one thing simplistic and robotic while you uncover the difficulties confronted by researchers.
First, image your self as a bee. You could have wings, permitting flight. Your imaginative and prescient isn’t as sharp anymore, worse than your grandfather’s along with his coke-bottle glasses, however you see issues extra rapidly. Life is skilled on a sooner timeline—what was as soon as a film is now extra like a collection of pictures in a slideshow.
The antennae protruding out of your head operate as fingers, ears, tongues, and noses, multi functional. You’ll be able to inform if somebody has visited a flower earlier than you—a flower you picked out of a subject of lots of by its scent, and which you discovered by following the instructions you felt a fellow bee dance for you contained in the pitch-black hive maybe ten kilometers out of your present place.
Chittka then invitations us to think about the lifetime of the bee. Upon exiting the hive for the primary time, you could study its location by means of a collection of flights—habits noticed in different central-place foragers equivalent to ants and wasps. Failure to acknowledge your hive and return house equals demise.
After you have memorized the situation of your hive, you then should efficiently navigate your technique to and from numerous resource-rich patches as effectively as potential, studying new places, the timing of sure flowers releasing their nectar, and the strategies required to govern different flowers into relinquishing theirs.
To this point, this sounds instinctual, a primary response to starvation. But Chittka presents extra analysis—historic and present—that gives insights into the cognitive abilities of bees. We study that bees can rely. They’ll study guidelines and categorize flowers. And so they can study from others, not solely which flowers are rewarding, however the way to entry them.
One in every of my favourite experiments, maybe for the movies that accompanied the publication, is of bumblebees pushing balls into holes to get rewards. This talent could be learnt by an observer bee and, what is really fascinating, it may be improved upon. The observer bee can resolve the duty by copying the aim somewhat than strictly copying the method, demonstrating an understanding of the duty and the specified final result.
However when would a bee ever must push a ball right into a gap to be rewarded with some “nectar”?
As Chittka rightly factors out, the questions we pose to grasp the minds of bees should have a organic relevance to make sense. That’s, we have to perceive what’s necessary to the survival of bees, what is crucial of their existence, and body our questions of intelligence and sentience round that facet. If we ask the incorrect questions, we’ll by no means absolutely perceive the solutions—like asking a fish to climb a tree and discovering it missing.

Consciousness and Emotion
The punch this e book packs is within the refined build-up to the ultimate chapters, whereupon it turns into more and more arduous to disclaim the “thoughts” of a bee.
Whereas it’s unimaginable to show consciousness in one other organism, the analysis Chittka has collated supplies a compelling argument. In The Thoughts of a Bee, you’ll learn that bees really feel feelings and ache, show metacognition (that’s, they know what they know), and present particular person variations of their potential to study, with quick and sluggish learners. Bees are conscious of their our bodies and the outcomes of their actions, and so they show intentionality by means of software use—beforehand solely acknowledged in people, primates, and the corvidae household of birds.
No matter whether or not you imagine a bee has a thoughts or not, globally there was a change in analysis practices as invertebrates are seen to expertise the world extra absolutely.
Ethics approval is required for work on some invertebrates, together with crustaceans and cephalopods, and statements of moral therapy of different invertebrates are required for submission of manuscripts to some journals. To counsel an invertebrate, equivalent to a bee, might have these fuller experiences of life is now not attracting ridicule, however as a substitute is creating an uncomfortable area for insect researchers, who might not want to confront the truth of their experiments.
We’ve underestimated the intelligence of bees and different “decrease” species for much too lengthy; it’s time to listen. Chittka reveals us that bees have the important thing elements of a thoughts: they’ve a illustration of area, they’ll study by statement, and so they show easy software use. Bees have demonstrated a versatile reminiscence, with concepts of what they wish to obtain, a capability to discover appropriate options to get it, and an consciousness of the potential outcomes of their very own actions.
Experiments have additional proven that bees seem to connect emotional states to rewards and punishments. Whereas their biology and expertise of the world may be very completely different to ours, it’s cheap to imagine that they do certainly possess a thoughts able to experiencing the wealthy tapestry of life now we have so lengthy thought solely out there to us.
Written with moments of levity and soaked in curiosity, The Thoughts of a Bee is a delight. Whereas some will not be able to ascribe sentience to one thing as “easy” as a bee, this e book will immediate you to query why not. As Chittka so eloquently put it in a latest speak: “We’re considering, struggling, having fun with beings in a world of different considering, struggling and having fun with beings, with completely different minds and perceptions.”
I for one am wanting on the world a bit in another way with that in thoughts.
