As the science of selection develops in the context of human reproduction, features such as the genetic improvement of health, athletic prowess or intelligence may become accepted grounds for choosing future children. Thus, the biological enhancement of the human race, so central to the discredited eugenic regimes of the twentieth century, may now be resurfacing under a new guise.

Unnerving similarities between earlier eugenic selection programmes and those now being proposed in the context of twenty-first century human reproduction, with the development of procedures such as gene editing, suggest that a more ‘sanitised’ era of a new eugenics has dawned. There is, therefore, an urgent need to consider and evaluate both current and future selection practices from a Christian perspective based on Scripture.

Calum MacKellar offers an accessible, inter-disciplinary analysis, blending science, history and Christian theology, enabling readers to develop an informed opinion about the topics encountered. To some degree, all members of society are affected by these new scientific developments in human reproduction, regardless of background, and will thus benefit from such a survey.
