We are lucky to live in an era where so much is being discovered about our minds and bodies. Unfortunately, oftentimes scientific inquiry is driven by political expediency and so it becomes difficult for the general public to know what to believe. Complicated data are reduced to sound bites that often bear little resemblance to the conclusion of the actual research being reported on. Information about same gender attraction has been caught in the throes of this war of words, trying to sway the public’s opinion towards a notion of biological inevitability. However, this viewpoint is inconsistent with other scientific evidence.
In the last ten years neuroscience has made incredible discoveries. My opinion is that this research has been more objective since it has not been for the purpose of supporting a specific political agenda as in the case of research on homosexuality. What scientists overwhelmingly agree on is that the human mind is much more plastic (malleable) than had previously been believed and that humans are capable of learning throughout their life span. How wonderful to realize that we have amazing capacities to influence our own thinking, feeling and behaving. We are not bound by our biology but can choose to maximize or minimize whatever genetic predispositions we may have-whether they are physical, emotional or intellectual. You can improve your coordination, increase your I.Q., alleviate most depressive symptoms, overcome the ravages of strokes, learn to speak a new language after 50, etc. It is widely held that every aspect of being human involves nature and nurture. So even though they have found a gene for racism, and for most everything else by the way, no one is making the claim that people are justified in acting on those predispositions The same gender movement would have you believe that your sexuality is the ONLY part of your humanness that is beyond your control-that you are “born that way”.
In a recent article in this paper Dr. Clifford cites one study done in 1993 by Dean Hamer. Dr. Hamer is someone with same gender attraction and his study was on self reported same gender men. However, rather than citing the researchers own opinion he cites the conclusion picked up by the news media-that “genetics plays a significant role in determining homosexuality”. Let me quote Dr. Hamer in his own conclusion “...”suggesting the possibility of sex linked transmission in a portion of the population,”at least one subtype of male sexual orientation is genetically influenced.” Hardly a ringing endorsement for a gay gene. A study done by Dr. Rice trying to replicate Hamer’s findings, found “ our study was larger than that of Hamer et al, we certainly had adequate power to detect a genetic effect as large as reported in that study. Nonetheless our data do not support the presence of a gene of large effect influencing sexual orientation…”
It would appear that all human behavior is influenced genetically. But exactly how is still not understood. The same gender movement has researched every possible angle to prove sexual orientation is not a choice and so far the findings show correlations, descriptions but not causation. So it is inaccurate and misleading to use science to bolster claims for equal rights. It would be more honest to say this is something the same gender movement really wants but not something they are owed or should be granted based on their biology. There is insufficient evidence for the claim that homosexuality is a condition but lots of evidence for the argument that homosexuality is like all other human behaviors a complex interplay between biology and environment.

1. LeVay, Simon, "A Difference in Hypothalamic Structure Between Heterosexual and Homosexual Men, Science, Volume 253: 1034-1037
2. Hamer, Dean, Hu, Stella et al. "A Linkage Between DNA Markers on the X Chromosome and Male Sexual Orientation", Science, Volume 261, July 16, 1993: 321-327.
3. Bailey, J.M. and Pillard, R.C. "A genetic study of male sexual orientation", American Journal of Psychiatry,150(2):272-277, 1993.
The first two studies have not been replicated and have serious methodological flaws. There is another gene study that is supposed to come out this year. The third researcher, Dr. Bailey was indicted for engaging in fraud and so his research has been questioned but again not by anyone outside of scientific circles. There are additional twin studies but they found lower than the 50% that Bailey found of identical twins exhibiting same gender attraction. Still only half of identical twins shared a homosexual attraction indicating that there is something else going on in the expression of same gender behavior.
There are a few organizations and or scientists who have been brave enough to present other interpretations for the data being reported by the mainstream media.
The first and third articles listed on the side bar are by Dr. Jeffrey Satinover and provide an easy to read explanation of genetic research.
Here is an additional link of a video showing three marriage and family researchers discussing concerns regarding same gender marriage. http://link.brightcove.com/services/link/bcpid1847329084/bctid1825879383
Listed below are three organizations dedicated to helping individuals and families dealing with same gender issues. They are excellent resources of information, research, treatment options, support groups, etc.

One last article on a different way to view the data .
Happy reading and viewing!
