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 澳大利亚, say odd and even categorisation – also called parity classification – had never been shown in non-human animals until now.

A new study, 发表在期刊上 Frontiers in Ecology, showed that honeybees can learn to do parity tasks which are considered to be abstract, high-level concepts in humans.
