One was filed on behalf of Kiko, a chimpanzee whose severe beating with a steel rod on a movie set left him partially deaf, and who was now forced to live in a cage in a cement storefront in Niagara Falls without chimpanzee companions. The last two were Hercules and Leo, 2-year-old chimpanzees seized from their parents and leased by Louisiana's New Iberia Research Institute to Stony Brook University. There they spent their entire childhood in a cage in the basement of a campus computer building, unable to play outdoors or live as part of a normal chimpanzee group. Worse, they endured thin wires being thrust into their muscles and were frequently forced to undergo general anesthesia, all to satisfy the curiosity of anatomy professors as to how humans evolved to walk on straight, rather than bent, legs.
