    We’ve learned bees can understand zero and do basic math. Now a new study shows their tiny insect brains may be able to connect symbols to numbers.

Adrian Dyer, a professor in the RMIT University, said the research showed brains far smaller than humans’ could know numbers. “Humans learn numbers as children, but being able to recognize what numbers really represent needs a certain level of cognitive (认知的) ability,” Dyer says, “Studies have shown primates (灵长类动物) and birds have this ability, but this is the first time we’ve seen this in insects.”

It’s important for humans to do the research. There are 86 billion neurons (神经元) in humans’ brains. Bees only have less than a million. If bees have the ability to learn something difficult to understand like human-made symbolic language, this will open up exciting new paths for future communication between humans and animals.

Studies have shown that a number of animals have been able to learn symbols of numbers, including parrots and monkeys. Monkeys were taught Arabic numbers and could order them correctly. An African grey parrot called Alex was able to learn numbers and could do simple calculation.

Understanding how tiny brains of bees manage information opens paths to technology, which is good for the future design of computing (计算) systems.
