Detailed explanation-1: -Until now odd and even categorisation, also called parity classification, had never been shown in non-human animals. In a new study, published today in the journal Frontiers in Ecology and Evolution, we show honeybees can learn to do this.

Detailed explanation-2: -Our results showed the miniature brains of honeybees were able to understand the concepts of odd and even. So a large and complex human brain consisting of 86 billion neurons, and a miniature insect brain with about 960,000 neurons, could both categorise numbers by parity.

Detailed explanation-3: -In the past, scientists have shown that bees have some surprising math skills. Now, new research shows that bees can even be trained to tell the difference between odd and even numbers. Before this, humans were the only animals known to have this ability.

Detailed explanation-4: -A new study has shown that honeybees can learn odd and even number categorisation - also called parity classification. A new study has shown that honeybees can learn odd and even number categorisation - also called parity classification. Till date this had never been shown in non-human animals.

Detailed explanation-5: -It might seem a little strange - bees are insects, after all; what do they know about mathematics? A lot, it turns out. These eusocial flying insects can add, subtract and even comprehend the concept of zero. “You can see their decision-making process in their movements and flight patterns,” Howard said.
