Last fall, a biochemist and scientific research consultant from New Zealand, Neil Whitehead, co-author with his wife of My Genes Made Me Do It, was in the United States to give a presentation at NARTH on some research he’s done regarding genetic contribution to homosexuality—primarily through twin studies. His wife, Briar, is the author of Craving for Love: Relationship Addiction, Homosexuality, and the God Who Heals.
While Dr. Whitehead was in the US, he was invited to come to Salt Lake City to give a fireside presentation—an abbreviation of his NARTH presentation—sponsored by Evergreen International, which I attended. In some of the discussions on here about the etiology of homosexuality, some of the info he presented kept coming to mind, and I wanted to be able to see a copy of his slide show to re-examine his stats. A copy of that slide show is now online.
Dr. Whitehead also maintains a website on the subject.
