Do the Ashkenazim share some genes with Palestinian Arabs? Journal axes gene research on Jews and Palestinians

This news goes back to 2021 but is a strange example of something being unsayable. Apparently, saying that Palestinian Arabs and Jews have some genes in common is "incorrect". But it is actually a central Israeli claim that they trace their origins to ancient Israel, a land that has also been called Palestine.

So Jews SHOULD have some Middle-Eastern genes -- and they do. Perhaps it's how you talk about the genetic commonality between Jews and Palestinian that raises hackles. Calling the two groups "almost identical" was undoubtedly a stretch. That could be nearly true of Mizrachi Jews (who come from Arab lands) but seems unlikely to be true of the Ashkenazim. Yet it seems to be the Ashkenazim who were studied in the paper concerned

A keynote research paper showing that Middle Eastern Jews and Palestinians are genetically almost identical has been pulled from a leading journal.

Academics who have already received copies of Human Immunology have been urged to rip out the offending pages and throw them away.

Such a drastic act of self-censorship is unprecedented in research publishing and has created widespread disquiet, generating fears that it may involve the suppression of scientific work that questions Biblical dogma.

'I have authored several hundred scientific papers, some for Nature and Science, and this has never happened to me before,' said the article's lead author, Spanish geneticist Professor Antonio Arnaiz-Villena, of Complutense University in Madrid. 'I am stunned.'

British geneticist Sir Walter Bodmer added: 'If the journal didn't like the paper, they shouldn't have published it in the first place. Why wait until it has appeared before acting like this?'

The journal's editor, Nicole Sucio-Foca, of Columbia University, New York, claims the article provoked such a welter of complaints over its extreme political writing that she was forced to repudiate it. The article has been removed from Human Immunology's website, while letters have been written to libraries and universities throughout the world asking them to ignore or 'preferably to physically remove the relevant pages'. Arnaiz-Villena has been sacked from the journal's editorial board.

Dolly Tyan, president of the American Society of Histocompatibility and Immunogenetics, which runs the journal, told subscribers that the society is 'offended and embarrassed'.

The paper, 'The Origin of Palestinians and their Genetic Relatedness with other Mediterranean Populations', involved studying genetic variations in immune system genes among people in the Middle East.

In common with earlier studies, the team found no data to support the idea that Jewish people were genetically distinct from other people in the region. In doing so, the team's research challenges claims that Jews are a special, chosen people and that Judaism can only be inherited.

Jews and Palestinians in the Middle East share a very similar gene pool and must be considered closely related and not genetically separate, the authors state. Rivalry between the two races is therefore based 'in cultural and religious, but not in genetic differences', they conclude.

But the journal, having accepted the paper earlier this year, now claims the article was politically biased and was written using 'inappropriate' remarks about the Israeli-Palestinian conflict. Its editor told the journal Nature last week that she was threatened by mass resignations from members if she did not retract the article.

Arnaiz-Villena says he has not seen a single one of the accusations made against him, despite being promised the opportunity to look at the letters sent to the journal.

He accepts he used terms in the article that laid him open to criticism. There is one reference to Jewish 'colonists' living in the Gaza strip, and another that refers to Palestinian people living in 'concentration' camps.

'Perhaps I should have used the words settlers instead of colonists, but really, what is the difference?' he said.

'And clearly, I should have said refugee, not concentration, camps, but given that I was referring to settlements outside of Israel - in Syria and Lebanon - that scarcely makes me anti-Jewish. References to the history of the region, the ones that are supposed to be politically offensive, were taken from the Encyclopaedia Britannica, and other text books.'

In the wake of the journal's actions, and claims of mass protests about the article, several scientists have now written to the society to support Arnaiz-Villena and to protest about their heavy-handedness.

One of them said: 'If Arnaiz-Villena had found evidence that Jewish people were genetically very special, instead of ordinary, you can be sure no one would have objected to the phrases he used in his article. This is a very sad business.'

For what interest it may have, the Abstract of the paper is below:

The genetic profile of Palestinians has, for the first time, been studied by using human leukocyte antigen (HLA) gene variability and haplotypes. The comparison with other Mediterranean populations by using neighbor-joining dendrograms and correspondence analyses reveal that Palestinians are genetically very close to Jews and other Middle East populations, including Turks (Anatolians), Lebanese, Egyptians, Armenians and Iranians. Archaeologic and genetic data support that both Jews and Palestinians came from the ancient Canaanites, who extensively mixed with Egyptians, Mesopotamian and Anatolian peoples in ancient times. Thus, PalestinianJewish rivalry is based in cultural and religious, but not in genetic, differences. The relatively close relatedness of both Jews and Palestinians to western Mediterranean populations reflects the continuous circum-Mediterranean cultural and gene flow that have occurred in prehistoric and historic times. This flow overtly contradicts the demic diffusion model of western Mediterranean populations substitution by agriculturalists coming from the Middle East in the Mesolithic-Neolithic transition

One wonders a little how their sample of Ashkenazi Jews was gathered. How reprsentative was it? Other studies have shown the Ashkenazim to have very little in the way of Middle-Eastern genes. Could that contradiction be a sampling artifact? It seems a pity that such concerns were not examined.
