NEW YORK -- A "study released today ")}reveals a critical, long-overlooked flaw
in the science behind the multi-billion dollar genetic engineering industry,
raising serious questions about the safety of genetically engineered foods.
In a new review of scientific literature reported in the February issue of
Harper`s Magazine, Dr. Barry Commoner, a prominent biologist demonstrates
that the bioengineering industry, which now accounts for 25-50 percent of
the U.S. corn and soybean crop, relies on a 40-year-old theory that DNA
genes are in total control of inheritance in all forms of life. According to
this theory -- the ``central dogma`` -- the outcome of transferring a gene
from one organism to another is always ``specific, precise and
predictable,`` and therefore safe.
Taking issue with this view, Commoner summarizes a series of scientific
reports that directly contradict the established theory. For example, last
year the $3 billion Human Genome Project found there are too few human genes
to account for the vast inherited differences between people and lower
animals or plants, indicating that agents other than DNA must contribute to
genetic complexity.
The central dogma claims a one-to-one correspondence between a gene`s
chemical composition and the structure of the particular protein that
engenders an inherited trait. But Dr. Commoner notes that under the
influence of specialized proteins that carry out ``alternative splicing,`` a
single gene can give rise to a variety of different proteins, resulting in
more than a single inherited trait per gene. As a result, the gene`s effect
on
inheritance cannot be predicted simply from its chemical composition --
frustrating one of the main purposes of both the Human Genome Project and
biotechnology.
Commoner`s research sounds a public alarm concerning the processes by which
agricultural biotechnology companies genetically modify food crops.
Scientists simply assume the genes they insert into these plants always
produce only the desired effect with no other impact on the plant`s
genetics. However, recent studies show that the plant`s own genes can be
disrupted in transgenic plants. Such outcomes are undetected
because there is little or no governmental regulation of the industry.
``Genetically engineered crops represent a huge uncontrolled experiment
whose outcome is inherently unpredictable,`` Commoner concludes. ``The
results could be catastrophic.``
Dr. Commoner cites a number of recent studies that have broken the DNA
gene`s exclusive franchise on the molecular explanation of inheritance. He
warns that ``experimental data, shorn of dogmatic theories, point to the
irreducible complexity of the living cell, which suggests that any
artificially altered genetic system must
sooner or later give rise to unintended, potentially disastrous
consequences.``
Commoner charges that the central dogma, a seductively simple explanation of
heredity, has led most molecular geneticists to believe it was ``too good
not to be true.`` As a result, the central dogma has been immune to the
revisions called for by the growing array of contradictory data, allowing
the biotechnology industry to unwittingly impose massive, scientifically
unsound practices on agriculture.
``Dr. Commoner`s work challenges the legitimacy of the agricultural
biotechnology industry,`` said Andrew Kimbrell, Director of the Center on
Food Safety. ``For years, multibillion dollar biotech companies have been
selling the American people and our government on the safety of their
products. We now see their claims of safety are based on faulty assumptions
that don`t hold up to rigorous scientific review.``
The "study reported in Harper`s Magazine")} is the initial publication of a new
initiative called The Critical Genetics Project directed by Dr. Commoner in
collaboration with molecular geneticist Dr. Andreas Athanasiou, at the
Center for the Biology of Natural Systems, Queens College, City University
of New York.
