The research presented at the “Primate Theory of the Mind” lecture only further adds to the wealth of observations of chimpanzee intellect, emotions and culture once only relegated to humans (“Chimps, people think alike,” 11/ 10). Unfortunately, despite this evidence, approximately 1,200 chimpanzees — some once free and wild in Africa — are still being held, many for decades now, in American laboratories.
But there is hope for those chimpanzees remaining in labs. Mounting public opposition to invasive research conducted on chimpanzees and the extremely high financial and ethical costs of keeping them in labs already have led to a noticeable decline in their use. The writing is on the wall: The United States needs to end the use of chimpanzees in biomedical research and testing — because chimps deserve better.
