There is a fear of science and scientists. It's strange to me that people don't realize that the way to deal with that fear is to learn about it. We scientists are not very fearful people. a samewhat different way, but we kmwe the same good and bad as everyone else. The negative things about scientists are the same as the negative things about anyone else. There's a lesson to be learned there, because if people would talk to us and learn what we're like, they would realize We look upon the world in shw tcaik A this, and they would then be less afraid of science. don't want to talk about scientific issues. But a lot of people They draw very firm lines. MOYERS: Bn't you think they say, ItLetts let Maxine Singer handle it. Let's let the scientists do it.t1 SINGER: Well, they do and they don't, because eventually it canes kr10cJcing on their door. One of the very good examples of this in our society is the constant trouble we have had for forty or fifty years with the notion of evolution. Every couple of years, this becomes an issue in American schools, and we fight this battle all over again. There are people who have a very fumlamntal belief in the Bible as a description of 6 the world an3 as essentially a scientific document, but they represent a very mall percentage of the population. Yet mre than fifty percent of Americans, when asked year after year, say they believe that creationism should be taught along with evolution in the schools. Thatis an amazing number. It tells us that over fifty percent of Americans, and that includes a lot of very highly educah ed Amricans, are very uneasy about the notion of evolution. I think itls because they think that if we accept the theory of evolution, we scmehm leave behind a lot of the premises on which our human interactions are based. MOYERS: Religious folks say that the work of people like Maxine Singer establishes the relationship of everything to a common ancestor, that genetics confirm evolutionary biology, and that it leads to a profoundly mechanistic view of the world, in which there is no room for God. That's part of the fear leadirig to the dete.rmination that creationism will be taught in the high schools along with evolution. SINGER: It is true that -ern genetics has confirmed all of the ideas of evolutionary biology. A very famous geneticist said, many years ago, that there was no way to think about the natural world that made any sense except in terms of evolution. If you try to think about the living world without the concept of evolution, it would be sarnething like teaching lawyers to be lawyers without reference to the United States Constitution.

And modern genetics has confirmed that- PE?ople fear the challenge of a mechanistic view of life, and that is indeed what modern genetics teaches =--a very mecham 'stic view of life.

SINGEEI: No, the best way to look at it is that a gene is like a sentence in an encyclopdia.

All tcgether, the sr; \\\an5 -+I&-- of cells in your bociy do all the things that make you who you are, and that make a corn plant what it is, and that make a yeast cell what it is.

ID=: SIN-: what are you trying to explore about it? Well, in fact, what my colleagues and I in my lab do is not quite looking at what a gene is like. It turns out that a lot of c%IIA doesn't clearly have any information, at least as far as we know now. It's as though you had an encyclopedia, and on every third page there was a lot of jabberwock. exactly the same jabbemock again--& two pages later, there it was again. And then you turned six more pages, and you repeated It doesn't look like a gene--that is to say, it doesn't look like a meaningful sentence. And I'm certainly confounded by the fact that it occurs so my times. My colleagues and I in the human gene that occurs probably on the A are looking at a..sdmme order of 100,000 times, and altogether mdkes up about five percent of the DNA in every cell. Why? We don't know. What is it doing? We don't know. I can't figure out what it is. DNC\ SC?..W@u\f. (h We do know that new copies of it can be made in i&e human cell and put in a new place in the W. And we know, thanks to the work of scrme human geneticists at Johns Hopkins, that it can cause mutations. That was a very exciting finding in the last year for us, because it says that this piece of gendc jahberwock can pi& itself up fm one place in the gen- and settle dawn somewhere else, where it can cause a mutation-in this particular case, two instances of the disease of hemophilia. So, it's very real and very serious. ID-: what is the value of finding this out? SINGER: The value is severalfold. First of all, if we can understand what mdkes such a sequence me about, we will have understood the cause of a certain amount of genetic disease. We will be able to understand the role of flexibility in the molecule. The analogy to 11 the encyclopedia falls dawn once you realize that INA raves itself abaut and changes in all of us, all the the. we'll learn, That's one of the things that mYEFG: There's a lot of talk in this city about the human gename project, which will cost billions of dollars. What is it? SINGER: To continue the analogy I've been using, it would be e equivalent to saying that we could write out th& encyclopedia for human INA, and that we would know all of the information in a human cell. We would how how to find it, as we do when we look in an inda of an encyclopedia, or when we look up sanething alphabetically. We would know how to turn to the gene that causes hemphilia when it's mutated. We would how how to turn to the page that says this gene is going to be important in causing a certain tumr. gene in a person, and perhaps make sane guesses as to whether that person is likely to develop a certain tumor or not. We would know hm to look at that MOYERS: So if you hew that, then you could begin to think about altering the gene to prevent the disease. SINGER: The genome project is defined ery grandly.

For example, right mer here in Maryland, at The anirral rights people say we SINGER: It's very difficult to argue that we are special as human beings without also aryuhg that we ought to pay special attention to our own species. our species who suffer from disease, stamation, an3 so forth. best ways we have of trying to help that suffering is experktation, learning new information about how living things work. questions we ask about living things, the only way that we have to answer them is to do a certain amount of experimentation on animals. Within that special attention is the need to help those of One of the For many of the Naw, there is no question but that work that has gone on in the past Some i-r me& A has misused animals unnecessarily. There is no question but that insufficient attention was paid to the lives and suffering of those animals.

SINGEE?: The animal rights people are misguided in sane of their concerns, and in the extranes to which they go. message which has been important. Many people within the scientific camunity deal with the same questions that are raised by animal rights people, but apprcach them in rational, thoughtful ways that are not extreme, and that allow for a balance between our need to help our awn specid species, and our need to pay sane attention to suffering animals. How would you respond to the more severe critics of genetic But they also have a core MOYERS: engineering, like Jeremy Rifkin, who says we had better be very careful what we release into the ernriromtent, because we donlt how enough yet about the unintended consequences. Genetic engineering ought to be done under only the most protected, sheltered, restricted circumstances imaginable. SINGEE?: Let me say first of all that Jeremy Riflcinls view of the situation is a very extreme one. we get the impression that they do because he is given a great deal of space on television, and in newspapers and magazines. Not many people take his view, although The release of organisms, which Rifkin still speaks about, was, of CoULse, the crux of the issue, ard that was raised not by m.

Now, Mr. fifkin knows that very, q strict guidelines were put into place and that, as a consecpence of a great deal of new scientific information, and consideration by scientists, ecologists, molecular biologists, and physicians, those guidelines have been relaxed. knows that there are still strict guidelines in place for those expriments that have the remotest possibility of being dangerous, that there is extensive review of experiments, and that there is extensive mrdtoring of what goes on. He is still crying about such things wen in the face of a history of responsibility on the part of scientists and the gavermmt of which we can all really be proud.

I myself have not learned big things in my am research. 11x1 not Watson or Crick or Weinberg, -. 1 learn 24 srrall things.
