Biological Parenthood: Gestational,Not Genetic

Common-sense morality and legislations around the world ascribe normative relevance to biological connections between parents and children. Procreators who meet a modest standard of parental competence are believed to have a right to rear the children whom they brought into the world. I explore various attempts to justify this belief, and find most of these attempts lacking. I distinguish between two kinds of biological connection between parents and children: the genetic link and the gestational link. I argue that the second can better justify a right to rear.
