although the two main sides of the abortion debate tend to agree that a human fetus is biologically and genetically human (that is, of the human species), they often differ in their view on whether or not a human fetus is, in any of various ways, a "person". pro-life supporters argue that abortion is morally wrong on the basis that a fetus is an innocent human person or because a fetus is a potential life that will, in most cases, develop into a fully functional human being. they believe that a fetus is a person upon conception. others reject this position by drawing a distinction between "human being" and "human person", arguing that while the fetus is "innocent" and "biologically human", it is not a "person" with a "right to life". in support of this distinction, some propose a list of criteria as markers of personhood. for example, mary ann warren suggests consciousness (at least the capacity to feel pain), reasoning, self-motivation, the ability to communicate, and self-awareness. according to warren, a being need not exhibit all of these criteria to qualify as a person with a right to life, but if a being exhibits "none" of them (or perhaps only one), then it is certainly not a person. warren concludes that as the fetus satisfies only one criterion, consciousness (and this only after it becomes susceptible to pain), the fetus is not a person and abortion is therefore morally permissible. other philosophers apply similar criteria, concluding that a fetus lacks a right to life because it lacks brain waves or higher brain function, self-consciousness, rationality, and autonomy. these lists diverge over precisely "which" features confer a right to life, but tend to propose various "developed" psychological or physiological features not found in fetuses.
