Genetic Engineering: A Fundamental Moral Approach. Recent discoveries in molecular biology have radically altered the science of genetics, posing new challenges for scientists and moralists alike. This new genetics requires a new model of creation that adequately addresses the weaknesses of two models of creation, the stewardship model and the co-creator model, that have been used to assess the limits and possibilities of genetic manipulation in human beings.
