A lot of hot air is around at the moment—and quite a bit of overselling—about advances in genetics, personalised genomics, and gene therapy. Only a small part of the variance in human illness is explained by genetics; most is explained by lifestyle, behaviour, and social factors such as poverty. Yet large sums are spent in a quixotic pursuit of the genetic basis for everything.
The hope—some say fear—is that we will be able to use advances in medical technology to reshape the genome of individual patients, curing ailments by changing somatic genes. Some even hope that we will be able to modify our species for the better by introducing changes into our germline.
Ethicists hotly debate this topic, arguing about the case for or against “perfection.” Do we have the right to develop technologies that would allow us to change the human genome? Some would say this is a duty. After all, if we could develop a …
