Retirement for chimps is, in its way, a perversely natural outcome, which is to say, one that only we, the most cranially endowed of the primates, could have possibly concocted. It's the final manifestation of the irrepressible and ultimately vain human impulse to bring inside the very walls that we erect against the wilderness its most inspiring representatives -- the chimps, our closest biological kin, the animal whose startling resemblance to us, both outward and inward, has long made it a ''can't miss'' for movies and Super Bowl commercials and a ''must have'' in our laboratories. Retirement homes are, in a sense, where we've been trying to get chimps all along: right next door.
