Let’s imagine walking in Florence and looking for a specific restaurant. Your smartphone, surprisingly, is not helping you out, but fortunately a local is giving you directions, “Go straight and turn left on the third street.” To find your destination, you need to use a specific kind of numerical information, which allows you to identify a street, between others, on the basis of its ordinal position.
Various species master this kind of ability; such as rhesus monkeys, rats, Clark’s nutcrackers, domestic chicks and honeybees.
