Most people know that humans are mostly right-handed, but fewer realise that many animals also show similar side preferences. This natural bias, known as handedness or lateralisation, plays an important role in survival and behaviour across species. From chimpanzees cracking nuts with a favoured hand to parrots gripping food with a preferred claw, handedness helps animals act more efficiently in their environment. It reflects the brain’s specialisation, where each side handles different functions. Studying handedness gives scientists insight into how brains evolved to divide tasks, conserve energy, and support complex behaviours such as communication and problem-solving. Handedness, in simple terms, is the consistent use of one side of the body over the other for certain actions. In h
