There are a number of ethical questions regarding the use of animals for biomedical research and particularly the use of the primates who are closest to humans genetically and who have been shown to have capacity for language and reason. Even if it is determined that humans have the right to use animals to further their own purposes then the question arises as to when and for what reason is the suffering or death of an animal justified. Also there is great debate on the validity of research that rests on the premise that primates such as chimps are close enough to humans to give accurate information. As new methods such as computer modeling and cell and tissue cultures are developed, they are showing higher levels of accuracy for some tests. These are only a few of the many questions facing anyone who is considering a stand on the issue of using primates or other animals in biomedical research. 8 pgs. 14 f/c. 12b.
