The Great Ape Project (GAP), founded in 1993, is an international organization of primatologists, psychologists, ethicists, and other experts who advocate a United Nations Declaration of the Rights of Great Apes that would confer basic legal rights on non-human great apes: chimpanzees, bonobos, gorillas, and orangutans. The rights suggested are the right to life, the protection of individual liberty, and the prohibition of torture. (See Declaration on Great Apes.)
