Many animal rights activists consider that all research carried out with animals is indefensible. This would apply especially to research with chimpanzees. I assume that chimpanzees are the closest relatives to humans and that they deserve ethical considerations which are similar to those accorded humans. Nevertheless, I believe that it is ethically justifiable to carry out certain types of experimentation with this species, as it is also with humans. I welcome the opportunity to defend this position here.
