Chimpanzees and other animals have moral status, which leads people not to mistreat them unnecessarily and to receive support in such cases. However, the question lies in their actual moral status. Most humans believe themselves to be superior or rather conservative and protective of our own species; believe in “speciesism”. As Peter Singer describes it, it is “prejudice or prejudice in favor of the interests of one's own species…against those of members of [the others]” (BBC). Humans are believed to be more self-aware than other species and to be more autonomous in their life purpose. This belief is thought to give humans moral superiority over other animals, but even then it is biologically natural to prefer one's own kind over others and treat them more favorably (BBC). Which leads to the argument that animals and even non-human primates cannot be considered equal to humans, to the consequentialist argument that the benefits to humans of biomedical research outweigh the harm to humans. animals.
