At some point in the next four months, Spain will likely become the first country to extend legal rights to great apes, thereby protecting gorillas, orangutans, chimpanzees, and bonobos from abuse, torture, and unnatural death. The measure will, in practical terms, prevent the inhumane confinement of and testing on great apes, which are singled out among nonhuman animals for their cognitive abilities—on par, it is believed, with a 1-year-old human child. But there's another ape that might be just as sensitive and intelligent as the great apes, and yet the Spaniards are prepared to offer it no special rights or protections. No one stands up for the gibbon.
