Glen Eyrie Spring Break 2015 Scientist Quotes

Glen Eyrie Notes, Session III quotes of scientists regarding homosexuality being genetic

  • Francis S. Collins, one of the world’s leading genetic scientists, head of the human genome project, in his book, The Language of God, “Evidence from twin studies does in fact support the conclusion that heritable factors play a role in male homosexuality. indicating that sexual orientation is genetically influenced but not hardwired by DNA, and that whatever genes are involved represent predispositions, not predeterminations.[1] (italics added)
  • Paul R. McHugh, M.D. – the University Distinguished Service Professor of Psychiatry at the Johns Hopkins University School of Medicine. “(1) there is no scientific consensus on what homosexuality is, and the number of people who fit in the class varies widely, depending on which definition of homosexuality is used and (2) there is no scientific consensus that homosexuality is exclusively or primarily genetic in origin.”[2]
  • Homosexual activist and Researcher Dean Hamer (author of the Gay Gene) “We knew that genes were only part of the answer. We assumed the environment also played a role in sexual orientation, as it does in most, if not all behaviors…”[3]
  • Researcher N. Mitchel, “Homosexuality is not purely genetic…environmental factors play a role. There is not a single master gene that makes people gay…I don’t think we will ever predict who will be gay” (Mitchell, 1995).[4]
  • Homosexual activist and researcher, Simon LeVay “It’s important to stress what I didn’t find. I did not prove that homosexuality is genetic, or find a genetic cause for being gay. I didn’t show that gay men are born that way, the most common mistake people make in interpreting my work. Nor did I locate a gay center in the brain.”[5]
  • Mark Breedlove, “a researcher at the University of California at Berkeley, demonstrated that sexual behavior can actually change brain structure. Referring to his research, Breedlove states: These findings give us proof for what we theoretically know to be the case-that sexual experience can alter the structure of the brain, just as genes can alter it. [I]t is possible that differences in sexual behavior cause (rather than are caused) by differences in the brain” (Breedlove, 1997, p. 801).[6]
