Book excerpt: These essays, written at the time when the Bill for Human Fertilization and Embryology Act (1990) was going through Parliament, touch on the British debate (on in vitro fertilization, gamete donation and maternal surrogacy) from an anthropological perspective. The implications of the medical developments that lay behind the Act are world-wide and these new procreative possibilities formulate new possibilities for thinking about kinship. The essays are informed by recent re-thinking of models of kinship in Melanesia.
