As the eugenic movement peaked and crashed, advances in reproductive technology made designer babies thrillingly, frighteningly possible. In the 1920s and early ’30s, visionaries imagined divorcing love and even marriage from procreation. Reproduction could be done scientifically, rationally, in a test tube. For optimists such as the biologist J B S Haldane, such ‘ectogenesis’ would permit humans to take the reins of their own evolution, eliminating disease and mutation, and perhaps enhancing qualities such as intelligence, kindness and strength of character. ... The development of molecular biology in the 1950s and ’60s transformed genes from abstractions into hard chemicals. Suddenly, scientists understood basically what a gene was. They thought they understood what a human was. ... By the mid-1980s, enthusiasts were discussing ‘genetic surgery’. The idea was to treat genetic disease by inserting a therapeutic gene into a modified virus and then ‘infect’ the patient; the virus would do the tricky part of inserting the gene into the chromosome. Through the 1990s, gene therapy was hyped almost as hard as CRISPR (clustered regularly interspaced short palindromic repeats), the new technology for ‘editing’ genes, is today. ... in terms of bringing us closer to a science-fiction world of intelligently designing our children – utopia or dystopia, take your pick – gene editing is more precise than accurate. The qualities we want in a child or in society can’t be had by tweaking a few nucleotides. There are no short cuts. To think otherwise is to conflate power with knowledge, to overestimate our understanding of biology, and to overestimate the role of genes in determining who we are.

It seemed absolutely crazy. The idea that an Iowa housewife, equipped with the cutting-edge medical tool known as Google Images, would make a medical discovery about a pro athlete who sees doctors and athletic trainers as part of her job? ... First, it was with her family’s Emery-Dreifuss, then when she thought they had lipodystrophy, and now she thought that she and Priscilla just must have a mutant gene in common because of the exact same pattern of missing fat. But how, then, did Priscilla get a double-helping of muscle while Jill’s muscles were scarcely there?
