Studies have shown that a number of non-human animals have been able to learn that symbols can represent numbers, including pigeons, parrots, chimpanzees and monkeys, but this is the first time we've seen this in insects.
RMIT UNIVERSITY: ‘We’ve learned bees can understand zero and do basic math, and now a new study shows their tiny insect brains may be capable of connecting symbols to numbers. Researchers have trained honeybees to match a character to a specific quantity, revealing they are able to learn that a symbol represents a numerical amount. It’s a finding that sheds new light on how numerical abilities may have evolved over millennia and even opens new possibilities for communication between humans and other species… Associate Professor Adrian Dyer said while humans were the only species to have developed systems to represent numbers, like the Arabic numerals we use each day, the research shows the concept can be grasped by brains far smaller than ours…
Studies have shown that a number of non-human animals have been able to learn that symbols can represent numbers, including pigeons, parrots, chimpanzees and monkeys. Some of their feats have been impressive — chimpanzees were taught Arabic numbers and could order them correctly, while an African grey parrot called Alex was able to learn the names of numbers and could sum the quantities. The new study for the first time shows that this complex cognitive capacity is not restricted to vertebrates…
“We take it for granted once we’ve learned our numbers as children, but being able to recognise what ‘4’ represents actually requires a sophisticated level of cognitive ability,” Dyer said. “Studies have shown primates and birds can also learn to link symbols with numbers, but this is the first time we’ve seen this in insects. “Humans have over 86 billion neurons in our brains, bees have less than a million, and we’re separated by over 600 million years of evolution. “But if bees have the capacity to learn something as complex as a human-made symbolic language, this opens up exciting new pathways for future communication across species”.’ SOURCE…
