  It should be noted that the U.S. National Institutes of Health has ceased funding biomedical research with chimpanzees, and many private companies have followed suit (Collins 2015; Human Society of the United States n.d.). With Gabon being the only remaining country that has a captive research population of chimpanzees (Nature 2011), the question remains as to how applicable DeGrazia’s arguments are to other great apes and other non-human primates.
