Abstract and Keywords

This article considers the extraordinary ways in which it is now possible to alter animals and to create new life forms by transgenesis and by the creation of hybrids and chimeras. Transgenic animals are created by transferring genes from one species to another. Hybrids are created by mixing the sperm of one species with the ovum of another. Chimeras are created by mixing cells from the embryo of one animal with those of a different species. In each case, one source of an animal so engineered could be a human being. The discussion uses the term “genetically modified animals” (GMAs), to refer to these transgenic animals, hybrids, and chimeras. It questions the adequacy of the ethics we currently have in place to exert proper control over and evaluate the creation of GMAs.

Keywords: transgenesis, hybrids, chimeras, gene transfer, human, GMAs
