Honeybees are the first non-human animals to demonstrate the ability to differentiate between even and odd numbers, a new study reveals.
Scientists, including those from Monash University in Australia, say odd and even categorisation – also called parity classification – had never been shown in non-human animals until now.
A new study, published in the journal Frontiers in Ecology, showed that honeybees can learn to do parity tasks that are considered to be abstract, high-level concepts in humans.
