We often think of culture as solely human. We think of our music, our clothes, our food, our languages. However, culture stretches far beyond Homo sapiens. As evidence of the existence of culture in other animal groups emerges (from insects, rats, fish to land mammals, primates and dolphins), humans need to rethink what it means to have culture. We must accept that what we have long considered our own might be shared.
