Improving animals, improving humans: transpositions and comparisons
n the past, domestic animals were improved by identifying those animals bearing desired traits and judicious breeding of these specimens. Today, controlled reproduction and biotechnology allow breeders to plan and direct reproductive development, to disseminate desired traits and accelerate genetic improvement. Moreover, in addition to changes in hereditary traits, there are multiple treatment techniques which stimulate performance, whether it be in horse racing or animal production. What are the repercussions of these methods? Can the issues raised by the practices of animal breeding and the stimulation of animal performance be transposed to human enhancement? Can they eventually shed new light on the issues raised by human enhancement?
