Genesis redux
A new form of life has been created in a laboratory, and the era of synthetic biology is dawning
IN THE end there was no castle, no thunderstorm and definitely no hunchbacked cackling lab assistant. Nevertheless, Craig Venter, Hamilton Smith and their colleagues have done for real what Mary Shelley merely imagined. On May 20th, in the pages of Science, they announced that they had created a living creature.
Like Shelley’s protagonist, Dr Venter and Dr Smith needed some spare parts from dead bodies to make their creature work. Unlike Victor Frankenstein, though, they needed no extra spark of Promethean lightning to give the creature its living essence. Instead they made that essence, a piece of DNA that carries about 1,000 genes, from off-the-shelf laboratory chemicals. The result is the first creature since the beginning of creatures that has no ancestor. What it is, and how it lives, depends entirely on a design put together by scientists of the J. Craig Venter Institute and held on the institute’s computers in Rockville, Maryland, and San Diego, California. When the first of these artificial creatures showed that it could reproduce on its own, the age of artificial life began.
The announcement is momentous. It is not unexpected. Dr Venter’s ambition to create a living organism from close to scratch began 15 years ago, and it has been public knowledge for a decade. After so much time, there is a temptation for those in the field to say “show us something we didn’t know.” Synthetic DNA is, after all, routinely incorporated into living things by academics, by biotech companies, even by schoolchildren. Dr Venter—a consummate showman—and the self-effacing Dr Smith (uncharacteristically in the foreground in the picture of the two above) have merely done it on a grand scale. … Continue Reading
