The noun “mimesis” comes from the Greek verb “mimeisthai,” which means “to imitate.” There are a few usages for this word. It can refer to art or literature that imitates real life, or it can be used in a sociological context to refer to one group of people imitating another. Mimesis is also seen in zoology, as many creatures imitate other animals or things. For example, a chameleon uses mimesis to imitate its surroundings.
