Honeybees Can Count

Yesterday, John Clayton followed up on my earlier post about bees. New research supports the idea that honeybees can count. This is despite the fact that a honeybee’s brain has fewer than one million neurons (compared to a human brain’s 86 billion neurons) and weighs less than one milligram (human brains weigh 1300-1400 grams).

Earlier research indicated that bees could count, add, subtract, and understand the concept of zero, but other scientists were skeptical of that data. The new research, published in the journal Proceedings of the Royal Society B, seems to support the earlier findings. Mirko Zanon, a neuroscientist at the University of Trento in Italy, said, “Our results show that [previous] criticism doesn’t hold when you consider the biology of the animal.”

Research showing that honeybees (Apis mellifera) can perform counting tests in the laboratory translates into useful skills in the field. For example, if honeybees can count, then counting flowers or petals could help them find the plants that offer the most nectar.

Processing numerical information by honeybees seems amazing when you consider the size of their brains. Learning the concepts of “greater than” and “less than” can be useful for the bee’s survival. The researchers in their report stated that “when viewed through a lens accounting for bee’s perceptual abilities, their behavioural responses observed in the numerical tasks investigated here are probably guided by actual numerosity rather than special cues.”

Of course, the report credited the numerical ability of honeybees to evolution, but couldn’t it be likely that the Creator placed in the tiny brains of these bees the neurological structure they need to survive?
