Folks, the study said NOTHING AT ALL about “identity”. It looked at genes that were ALREADY KNOWN to be sexually dimorphic and just changed where the probable mechanism of the dimorphism was located. Likewise, it seems that people here are woefully ignorant of what “sexual dimorphism” means. “Sexual dimorphism” does NOT refer to “sexual identity”. Sexual dimorphism concerns things like men having beards (usually) and women not (usually). It concerns size differences between male and female gorillas. It refers to physical traits that distinguish between sexes. This study demonstrated that XX vs XY CHROMOSOMAL differences can be determinative in at least some aspects of sexual dimorphism.
Let’s take this through in steps:
1: The study determined that XX vs XY is fundamentally and directly related to sexual dimorphism. It is not just a matter of hormonal load.
2: If this study is taken as somehow “groundbreaking” or “normative”, the logical conclusion is that males SHOULD all be “masculine” and females SHOULD all be “feminine”, if this study is the end-all and be-all of “scientific truth” on “gender identity”. Indeed, if this study is taken as somehow “concluding” or “resolving” anything at all, it “resolves” against variation in “sexual identity” having a biological “cause”. Read the whole paper, not the digested-for-the-ignorant press releases. Indeed, to claim that this paper “resolves” the matter of “sexual identity” would require that one either presume that “maleness” or “femaleness” is “supposed” to be locked tight by XX vs. XY and that anything that deviates from this should be considered “abnormal”. Really, read the full report.
Here is a digest of what they did:
They measured expression of XX vs. XY cell cultures in identical hormonal environments. The XX and XY cultures showed measurable differences in certain proteins. They selected a handful of genes to check for mRNA. These genes also segregated along a simple XX/XY basis. Thus, if one is to draw a universal conclusion from one study (a foolish thing to do), one would draw the conclusion that, in a normal organism, XX/XY would determine everything having to do with “sexual identity” and anything that deviates from this is abnormal and unnatural. Read the full study, not the popular press misinterpretations.
However, in the real world, this study will not be taken as “resolving” the matter. It only points to a more complex set of cascades determining SEXUALLY DIMORPHIC TRAITS.
The term “sexual identity” is not used ANWHERE AT ALL in the actual study–if it had been, the editors and reviewers would have sent it back for revision. The data says nothing at all about sexual identity. Go to a good medical university library and check the issue of Molecular Brain Research.
I predict that nobody will do this. I predict that the dogmatics will still bleat on with their little dogmas on each “side” of this matter and pretend that the study said whatever they wanted it to say, regardless of what the real paper has to say.
