Search
for "Gay Gene" Is "Bad Science" Says Nebraska Professor
By Peter J. Smith
UNITED STATES,
August 8, 2007 (LifeSiteNews.com) - Genes, environment, and self-agency
determine human behavior says an expert on behavioral genetics, who also says
that homosexual politics and not good science is behind the search for the
"gay" gene.
Douglas A. Abbott,
PhD, a professor of Child, Youth, and Family Studies at the University of
Nebraska, calls the "hypothetical evidence" for genetic determinism
of homosexuality" both "overstated" and "overrated."
"Except for
the rare physical abnormalities (such as Huntington's Disease) at the present
time, there is no evidence of a direct causative link between a single gene and
complex psycho-social behavior such as sexual preference," says Abbott.
In his July
article for the National Association for Research and Therapy of Homosexuality
(NARTH), Abbott explains that much of the public perception is misguided about
the relationship between genes and behavior. Media reporting aids this
confusion with headlines such as "Gene X Found to Cause Behavior Y".
Abbott, however, says this is a "simplistic" view of the science of
behavioral genetics, which studies "how genes, operating within their
complex environments, connect to human environments."
"Environment"
in behavioral genetics means any non-genetic influence, including internal
biological factors such as nutrients, bacteria, viruses, and medicines, and
external forces on a person such as parenting, family life, peers, the media,
geography, war, calamities, etc.
While genetics
play a role in a person's predispositions, this is a far cry from
predetermining that a person will engage in certain behaviors - such as
homosexuality - a view corroborated by Dr. Francis S. Collins, the head of the
Human Genome Project.
Abbott employs
excellent analogies to explain the relationship of genes and environment to
human behavior, perhaps the most lucid being the image of a sailboat. A
sailboat needs a hull (genetic dispositions) and sails (environmental factors),
but most importantly a captain (free agency of the will) who "may be
constrained by genes and environment - but he is not absolutely determined by
them."
Supported by the
authority of other numerous experts in the field of behavioral genetics, Abbott
asserts there is no undisputed evidence that same-sex behavior is hard-wired
into a person. Abbott also exposes the methodological, sampling, and interpretation
flaws behind the "genetic theory of homosexuality" formulated in the
early 1990s in three problematic studies.
"It is
obvious to me, and to many others, that environmental factors play the major
role in same-sex behavior, if this were not so how does one explain the
thousands of men and women who have left homosexuality," writes Abbott.
One such ex-homosexual is high profile former homosexual activist leader
Michael Glatze, who embraced homosexuality at 14, but at age 30 "seriously
began to doubt," and this year renounced his homosexuality, and embraced
Christianity.
In
conclusion," says Abbott, "I believe that the genetic evidence for
homosexuality is just not there. It's the values and politics of homosexuals
and their supporters that is driving the gay gene agenda, not good
science."
