From the ashes of classical concepts, a new view arose. It said that a concept is represented in the brain as the best example of its category, known as the prototype. For example, the prototypical bird has feathers and wings and can fly. Not all instances of “Bird” have these features, such as ostriches and emus, but they are still birds. Variation from the prototype is perfectly fine, but not too much variation: a bee is still not a bird, even though it has wings and can fly.
