Many believe that culture is an exclusively human phenomenon. But this book is about cultures whose bearers are not people: they are wild animals that inhabit the virgin regions of our planet. Karl Safina proves that sperm whales, macaws or chimpanzees are also able to recognize themselves as part of a community that lives in its own way and has its own traditions. Safina proves that for both animals and people, culture is the answer to the eternal question: "Who are we?" Culture makes individual members of a species feel like a group. But cultural groups often tend to avoid each other, and even to be at enmity. By demonstrating that this tendency is equally characteristic of a variety of animals, Safina explains why we humans can never get rid of intercultural conflicts, even though the differences between us often do not have a significant objective basis.
