Genetics, Bioethics and Space Travel: GATTACA
It has been said that all stories set in the future say more about the concerns of the time in which they are written than they do about future possibilities. Long before the genome era, writers were investigating the possibility of changing the biological make-up of humans. Questions about human biology, identity and eugenics (from the Greek ‘well-born’) have been raised by writers ever since Plato; classic novels addressing these issues include H.G. Wells's The Island of Doctor Moreau (1896) and Aldous Huxley's Brave New World (1931). Eugenics in fiction passed out of fashion after the Second World War, but recent developments in genetics and genomics have brought these ideas into the foreground again.
