Honeybees pass their math test, upending an animal intelligence debate

We've run the numbers and the verdict is in: Honeybees do have the ability to process numerical information. New research led by Monash University has now addressed recent international debate over whether bees are truly assessing numbers or simply reacting to visual patterns.

The study highlights the necessity of designing cognitive experiments that align with an animal's specific sensory and biological constraints. When stimuli are evaluated from a bee's-eye view, the evidence for numerical cognition is strengthened rather than diminished.

The study, published today in Proceedings of the Royal Society B: Biological Sciences, re-examined previous critiques of bee intelligence by accounting for the honeybee's unique sensory and perceptual constraints. By evaluating experimental stimuli from a biologically relevant perspective, researchers demonstrated that previous criticisms, which suggested bees were merely sensitive to visual cues like spatial frequency, do not hold up.

Monash University Senior Lecturer Dr. Scarlett Howard, from the Monash School of Biological Sciences, said the findings underscore the importance of avoiding human-centric biases in animal research.

"We must put the animal's perspective first when assessing their cognition or we may under or overestimate their abilities," said Dr. Howard. "We see and experience the world quite differently from animals, so we must be careful of centering human perspectives and senses when studying animal intelligence."

The research team argues that to accurately assess cognitive abilities, experiments must be designed to match the natural sensory capacities of the subject species.

Dr. Mirko Zanon, from the Center for Mind Brain Sciences at the University of Trento and first author on the study, said that ignoring how an animal perceives the world risks leading scientists to the wrong conclusions.

"There has been a debate about whether bees are really 'counting' or just reacting to visual patterns. Our results show that this criticism doesn't hold when you consider the biology of the animal," said Dr. Zanon. "When we analyze the stimuli in a way that reflects how bees actually see the world, what remains is actual sensitivity to number."

Dr. Howard added, "It can be challenging to put ourselves in the mind of a bee to imagine how they see the world, but trying to see the world through an animal's eyes is an essential part of our work. The bees always surprise us with how they move through the world, interpret our questions, and make decisions."

Damn the bees are doing better than i did last semester

And they also produce delicious fluid out of their ass or something.

At least i still got that going for me

I read the study. I don't see where they actually test the bees on numbers. All I see is testing their visual acuity with barcode-style patterns.

Just vomit, so, from their mouths. I think

They have a separate honey stomach, so it's nice clean vomit.
