Chimpanzees - An Unnatural History An excellent PBS Production which discusses human - chimpanzee interaction. You can find more information about this program at Chimpanzees. Chimpanzee DNA is 98% the same as humans, so are they "people"? If so, is it ethical to use them for medical experments? There is an excellent book which describes how "human" chimpanzees are. It is Next of Kin by Roger Fouts. I believe that this question needs to be discussed in a rational and impartial forum. I welcome comments from both sides of this issue.
