Are "Human" Rights Discriminatory? Great Apes and Us

Peter Singer congratulates the Spanish parliament for endorsing the idea that great apes, such as chimps, gorillas, bonobos, and orangutans, deserve rights of life, liberty and protection from human torture and slavery. Great apes, according to Singer, should only be in captivity for purposes of conservation since they have rich intellectual and emotional lives on par with humans.

Do the great apes deserve the protection and consideration usually given to human beings through international human rights law?
