Still other people think that animal testing is acceptable because animals are lower species than humans and therefore have no rights. These individuals feel that animals have no rights because they lack the capacity to understand or to knowingly exercise these rights. However, animal experimentation in medical research and cosmetics testing cannot be justified on the basis that animals are lower on the evolutionary chart than humans since animals resemble humans in so many ways. Many animals, especially the higher mammalian species, possess internal systems and organs that are identical to the structures and functions of human internal organs. Also, animals have feelings, thoughts, goals, needs, and desires that are similar to human functions and capacities, and these similarities should be respected, not exploited, because of the selfishness of humans. Tom Regan asserts that “animals are subjects of a life just as human beings are, and a subject of a life has inherent value. They are . . . ends in themselves” (qtd. in Orlans 26). Therefore, animals’ lives should be respected because they have an inherent right to be treated with dignity. The harm that is committed against animals should not be minimized because they are not considered to be “human.”
