dna is the construction material of the future

spiegel |  George Church, 58, is a pioneer in synthetic biology, a field whose aim is to create synthetic DNA and organisms in the laboratory. During the 1980s, the Harvard University professor of genetics helped initiate the Human Genome Project that created a map of the human genome. In addition to his current work in developing accelerated procedures for sequencing and synthesizing DNA, he has also been involved in the establishing of around two dozen biotech firms. In his new book, "Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves," which he has also encoded as strands of DNA and distributed on small DNA chips, Church sketches out a story of a second, man-made Creation.

SPIEGEL recently sat down with Church to discuss his new tome and the prospects for using synthetic biology to bring the Neanderthal back from exctinction as well as the idea of making humans resistant to all viruses.

SPIEGEL: Mr. Church, you predict that it will soon be possible to clone Neanderthals. What do you mean by "soon"? Will you witness the birth of a Neanderthal baby in your lifetime? 

Church: I think so, but boy there are a lot of parts to that. The reason I would consider it a possibility is that a bunch of technologies are developing faster than ever before. In particular, reading and writing DNA is now about a million times faster than seven or eight years ago. Another technology that the de-extinction of a Neanderthal would require is human cloning. We can clone all kinds of mammals, so it's very likely that we could clone a human. Why shouldn't we be able to do so? 

SPIEGEL: Perhaps because it is banned? 

Church: That may be true in Germany, but it's not banned all over the world. And laws can change, by the way. 

SPIEGEL: Would cloning a Neanderthal be a desirable thing to do? 

Church: Well, that's another thing. I tend to decide on what is desirable based on societal consensus. My role is to determine what's technologically feasible. All I can do is reduce the risk and increase the benefits. 

SPIEGEL: So let's talk about possible benefits of a Neanderthal in this world.

Church: Well, Neanderthals might think differently than we do. We know that they had a larger cranial size. They could even be more intelligent than us. When the time comes to deal with an epidemic or getting off the planet or whatever, it's conceivable that their way of thinking could be beneficial.
