Squirrels that favour one side of their body are slower learners compared with those who use both paws. A study found that squirrels that favour one side of their body performed worse at tasks that required learning. Many animals have a preferred side of the body for carrying out certain actions, though the strength of this preference can vary. This could help animals survive, as being strongly lateralized is linked to better cognitive performance. In humans research suggests that ambidextrous people may be more creative.
