There’s some additional bad news out there for the “party of science” (as the Democrats have taken to calling themselves) and particularly for transgender advocates. But even if you have no interest in such social justice topics, a new study published by geneticists in Israel is still pretty fascinating. The Liberty Council has a report this week on new research material coming from Israel’s Weizmann Institute of Science, where scientists have undertaken an exhaustive study of genetic differences between the two genders which go far beyond just what’s found in their 23rd chromosomal pair or what sorts of genitalia they display externally. And some of this research could have far reaching implications in terms of fighting diseases and solving other medical mysteries on top of sorting out this “gender vs sex” question which liberals keep trying to push.

A recent study released from Israel’s Weizmann Institute of Science refutes propaganda from LGBT activists who detach gender completely from sex and promote that men can become so-called “women” by merely “identifying” as female, and vice-versa. Professor Shmuel Pietrokovski and Dr. Moran Gershoni, both researchers from the Weizmann Institute’s Molecular Genetics Department, “looked closely at around 20,000 protein-coding genes, sorting them by sex and searching for differences in expression in each tissue. They eventually identified around 6,500 genes with activity that was biased toward one sex or the other in at least one tissue, adding to the already major biological differences between men and women.”

You can access the study here in .pdf form and browse through it. They discovered all manner of fascinating things, some of which seem obvious in retrospect while others are quite surprising. They identified specific genes which are directly associated with hair growth in skin cells. These genes are far more widespread in men than women, showing up in different places. (The result of that should be obvious.) One of the more surprising developments (at least to me) came in the area of mammary glands. Both males and females have all of the “equipment” to support lactation, but it’s almost never seen in men. The study identified specific genes in men which apparently turn off that process since it’s not needed. Some others would be easier to predict, such as higher levels of muscle building genes in men as opposed to higher levels of genes which are related to fat storage in women. The list goes on.

But mostly, this is just one more brick in the wall for the folks who seem to insist on “listening to the scientists” except when it’s inconvenient to do so. Whenever this debate comes up, someone inevitably tries to point to a single study done years ago hinting that the brain waves of transgender people match those of people of the opposite sex. But further research showed that those results couldn’t be reliably repeated under laboratory conditions. To boot, experts in the field have already admitted that they can’t tell a male brain from a female brain in those scans to begin with. By comparison, any deep dive into readily measurable and repeatable genetic studies shows the true nature of our species, as well as the striking and generally wonderful difference between our two genders which are established basically at the moment of conception.
