Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council www.national-academies.org Copyright © 2003 National Academy of Sciences. All rights reserved.

Gardner, 1965, upon appointment as the Secretary of the Department of Health, Education, and Welfare Rarely in the modern history of humans has biology played such an important role in human affairs as it does today. In the eighteenth and nineteenth centuries, explorers stimulated the first major advance in biology by bringing back countless new species that Darwin, and others, put into a logical order based on the theory of natural selection. The development of evolutionary thinking and the clarification of the rules of genetic inheritance resulted in the theoretical base for targeted artificial selection—an essential component of progress in biology and agriculture. A second major advance currently is underway. Due to the basic understanding of inheritance at the molecular level and the tools this has made available to biologists, it no longer is necessary to depend upon natural or artificial selection and breeding of progeny to produce new and improved individuals. Genes from the same or other species can be inserted into a genome, or the activity of a specific gene can be blocked. Further, once the genome has been altered artificially, large numbers of new plants and animals ix Copyright © 2003 National Academy of Sciences. All rights reserved.

Producing animal models of human diseases for research, improving medical procedures, and increasing food production are but three modern advances that already have come to pass. More advances are predicted for the future. The committee— early in its discussions—recognized that not everything that bloomed from the biotechnology garden was a flower ready to be picked for the human bouquet. As was true for other technologic advances in the past, advances do not come without expected and unexpected risks. The committee also recognized that the technology it was studying is in its infancy. Many of the problems, such as inefficient reproduction and production of abnormal offspring, are receding as the technology advances. Therefore, the committee presents a “snapshot” of biotechnology and of potential concerns about that technology at present. In view of the rapidly-changing biotechnologic landscape, federal agencies with responsibility for ensuring food safety, maintaining modern medical treatment standards, minimizing environmental impacts, and ensuring the welfare of animals requested that a committee formed by the National Research Council (NRC) of the National Academies explore concerns related to animal biotechnology. A committee of 12 scientists, physicians, and experts in regulatory issues accepted the task of defining science-based concerns associated with products of animal biotechnology. The committee’s report presents science-based concerns it identified but it does not contain specific recommendations. Identification of the concerns will allow others to develop regulatory policy where appropriate. While the focus of the committee was on the scientific information that could clarify the issues, it remained aware of the social and other policy issues involved in moving biotechnologic advances from the laboratory to the “real world.” Thus, assuming a bit of flexibility in our charge, our report addresses some of the policy issues involved as well. In a sense, almost any issue related to a technologic advance can be a concern. The committee attempted to place concerns in relative priority order within sections of the report (i.e., hazards associated with the techniques themselves, food safety, environmental impacts, and animal welfare). In only a few cases was it possible to state that an issue brought to our table was not of concern. Much of the basic biology underlying the techniques remains to be discovered, and we have only partial information on the consequences of using biotechnologic techniques. This is true especially in terms of the environmental concerns raised. It became quickly apparent that more information was needed to assess the priority of concerns raised. Only more research will resolve this problem. The committee relied heavily on published information, on presentations made by experts at an NRC-sponsored workshop, and on previous NRC reports. The NRC report, Environmental Effects of Transgenic Plants: The Scope and Adequacy of Regulation—recently completed by experts from the botanical half of the biologic world—was a valuable source of information.
