New Paper Proposes Epigenetic Pathway to Homosexuality (UPDATED)

I am still reading the paper by William Rice, Urban Friberg and Sergey Gavrilets (available for review here) and have asked several other scientists for their opinion of it.  It is a complex argument but one which initially seems compelling to me.

Here is the abstract:

Male and female homosexuality have substantial prevalence in humans. Pedigree and twin studies indicate that homosexuality has substantial heritability in both sexes, yet concordance between identical twins is low and molecular studies have failed to find associated DNA markers. This paradoxical pattern calls for an explanation. We use published data on fetal androgen signaling and gene regulation via nongenetic changes in DNA packaging (epigenetics) to develop a new model for homosexuality. It is well established that fetal androgen signaling strongly influences sexual development. We show that an unappreciated feature of this process is reduced androgen sensitivity in XX fetuses and enhanced sensitivity in XY fetuses, and that this difference is most feasibly caused by numerous sex-specific epigenetic modifications (“epi-marks”) originating in embryonic stem cells. These epi-marks buffer XX fetuses from masculinization due to excess fetal androgen exposure and similarly buffer XY fetuses from androgen underexposure. Extant data indicates that individual epi-marks influence some but not other sexually dimorphic traits, vary in strength across individuals, and are produced during ontogeny and erased between generations. Those that escape erasure will steer development of the sexual phenotypes they influence in a gonad-discordant direction in opposite sex offspring, mosaically feminizing XY offspring and masculinizing XX offspring. Such sex-specific epi-marks are sexually antagonistic (SA-epi-marks) because they canalize sexual development in the parent that produced them, but contribute to gonad-trait discordances in opposite-sex offspring when unerased. In this model, homosexuality occurs when stronger-than-average SA-epi-marks (influencing sexual preference) from an opposite-sex parent escape erasure and are then paired with a weaker-than average de novo sex-specific epi-marks produced in opposite-sex offspring. Our model predicts that homosexuality is part of a wider phenomenon in which recently evolved androgen-influenced traits commonly display gonad-trait discordances at substantial frequency, and that the molecular feature underlying most homosexuality is not DNA polymorphism(s), but epi-marks that evolved to canalize sexual dimorphic development that sometimes carryover across generations and contribute to gonad trait discordances in opposite-sex descendants.

The Christian Post did a quick piece on this study but did not interview anybody with any expertise about the research. Instead, they reached out to David Pruden who made the following statement:

“The theoretical model itself attributes only 10-14 percent of the factors to genetics or epigenetics. That leaves the remaining 85 percent or so of the factors to environmental influences,” said Pruden.

I don’t see anything like that in the paper so I can’t evaluate what he is claiming here. This sounds like the usual NARTH misreading of the genetic evidence but not the Rice et al paper.

UPDATE: Dr. Rice wrote to say that Pruden’s account is inaccurate. In response to my question: “Are you intending to account for homosexuality whenever it occurs?” Dr. Rice replied:  “Yes, we think that carry-over epi-marks have the potential to account for most homosexuality.”

The Reparative Therapy Makeover: Orange You Glad I Didn’t Say Banana?

In the complaint filed by the Southern Poverty Law Center against Jews Offering New Alternatives for Healing (JONAH), there are strange allegations made by the plaintiffs.  One of the strangest is the following from page 16 of the SPLC complaint:

orangesJONAH

In this paragraph, Alan Downing is a life coach who works for JONAH and was until recently recommended by Richard Cohen’s International Healing Foundation. Ferguson is one of the plaintiffs represented by the Southern Poverty Law Center. While some defenders of reparative therapy might think the plaintiffs are making this stuff up, the allegations sound believable to me.

The scenario in the complaint sounds like a description of the “Getting His Balls Back” technique suggested in manuals used to guide the New Warriors Training Adventure as put on by the Mankind Project.  Over the years, JONAH and NARTH leaders have recommended the New Warriors Training Adventure as a means of building masculinity and reducing same-sex attraction so it is not surprising to see the same processes used in their efforts with clients.

The Balls Back process is described in this 2002 manual (p. 12) written for NWTA by Steve Kushner:

BALLS BACK

WHEN TO USE

– He has given up or lost his power, masculinity or balls to someone and he wants it/them back

WHAT TO DO

– Place 2 tennis balls or oranges in Bad Role Player’s hands that are behind his back

– ASK HIM:

“Does he/she have your power, masculinity, balls?”

“Are you ready to take it/them back?”

(Have Bad Role Player bring hands out in front and taunt initiate)

– TELL HIM:

“The time is now, the place is here!” (emphasis added)

And then in this 2005 “Guts Guide” (Warriors call these processes “guts work”) by Martin Lassoff, the process is described in more detail.

2. Getting His Balls Back

When the initiate feels he has lost his courage, power or maleness to someone and wants to get it back, this is referred to as Getting His Balls Back. This process includes a Gauntlet.

Position a man at the end of a Gauntlet holding oranges or tennis balls (symbolizing his balls). (emphasis added)

The Gauntlet is described in the SPLC complaint as a “human chain” which the client must break through in order to grasp the oranges. This achievement is supposed to symbolize the client getting his “balls back.”

A book by Steven Segell which includes a description of a New Warriors weekend also outlines the process:

At 1:25 in this Colbert Report, Michael Ferguson described the technique for CNN (really you must watch the whole thing).

So it seems clear that the “oranges therapy” is derived from processes associated with the Mankind Project, an organization which Joseph Nicolosi, Arthur Goldberg, David Pickup and Richard Cohen have recommended.

Speaking of David Pickup, he told NBC News “I don’t do oranges therapy, and I don’t do naked therapy.” I established last week that as a New Warrior staff member, Pickup has recommended the New Warrior Training Adventure which involves nudity. Now today, I document that the very same “oranges therapy” Pickup said he didn’t do is also recommended by reparative therapists.
