Why would we show an optical illusion to a monkey or a sparrow? To learn how they experien

Animals may inhabit the same world as us, but new research shows how their perceptions of what is around them differsImagine standing in your garden. A bumblebee whizzes overhead too quickly to follow, a sparrow darts from the fence to the trees, and a snail lugs itself across th
