A German town built a granary atop its Jewish cemetery. Now the bones are yielding insights about Ashkenazi DNA.
BERLIN (JTA) – The city of Erfurt in central Germany is home to an impeccably restored medieval synagogue made possible because local Jews had been expelled long before the Nazis began their campaign to destroy Jewish sites.
Now, Erfurt’s long-hidden Jewish past is again offering new insights — this time about the genetic history of Ashkenazi Jews.
Human remains from a medieval Jewish cemetery in Erfurt have allowed what researchers say is the largest ancient Jewish DNA study to date. Conducted without disinterring any remains, in keeping with Jewish law, the study published Wednesday in the scientific journal Cell found that Erfurt’s medieval Jewish community was more genetically diverse than their modern-day cousins, and carried many of the same Jewish genetic diseases — such as Tay Sachs and cystic fibrosis — that affect Ashkenazi Jews today.
“There have been many previous DNA studies, but not of Jews,” said geneticist Shai Carmi, a professor at the Hebrew University of Jerusalem, whose search for study material led him to an archaeological dig at the Jewish cemetery in Erfurt. He and his collaborators were able to analyze DNA of 33 individuals who died between 1270 and 1400, using teeth they found there.
The study follows a similar analysis revealed in August by researchers in England, who studied the DNA from skeletons found at the bottom of a medieval well and concluded that the remains were likely of victims of an antisemitic massacre in 1190. Analysis of six individuals prior to their identification as Jewish revealed that Ashkenazi Jews developed a unique genetic variation centuries earlier than realized.
The Erfurt analysis also includes samples from before the epidemic of Black Death that was until recently understood to have created the genetic “bottleneck” that created the genetic markers common among Ashkenazi Jews today.
Erfurt’s Jewish settlement existed from the 11th to 15th century, with a brief gap following a 1349 massacre perpetrated after the Jews were falsely blamed for causing the bubonic plague. Surviving Jews returned there, but after all Jews were expelled once and for all in 1454, the city built a granary on top of the Jewish cemetery.

In 2013, the city approved the repurposing of the unused granary into a parking lot. Because it was an historic site, a rescue excavation was initiated, overseen for the State of Thuringia by German archaeologist Karin Sczech.
Meanwhile, Carmi had been looking for Jewish cemeteries anywhere in the world “where we could analyze remains already excavated,” he told JTA in a telephone interview from Jerusalem. “I consulted historians and eventually reached the archeologist in Erfurt.” Fortunately, he said, “they still hadn’t reburied the remains.”
He approached Sczech, who later became a co-author of the new study. In 2018, with a supportive judgment from Rabbi Ze’ev Litke — an Israeli expert on genetics and Jewish law — and permission from Erfurt’s then-rabbi, Benjamin Kochan, work began to extract and analyze DNA from detached teeth found in the graves. (About 500 Jews live in Erfurt today, most of them having migrated from the former Soviet Union since 1990.)
American geneticist David Reich picked up the teeth and brought them back to the department of human evolutionary biology at Harvard University in Cambridge, Massachusetts, where drilling and DNA extraction took place.
While the skeletons were reburied, the teeth are still stored at the research institutes where they have been analyzed, in case scientists need to retest to verify the result.
The project provides an ethical basis for studies of ancient Jewish DNA, Carmi said. “Of course we couldn’t just go to a cemetery and dig and take out skeletons; this would be prohibited,” he said, referring to Jewish law prohibiting the removal of bones from where someone was buried.
But Litke opined that the study could be done, because the bones already had been disturbed for an unrelated reason. “He recommended using teeth, as the analysis does almost no damage,” Carmi said.
There are many motivations to study Jewish DNA: One can find lost relatives going back a few generations, and answer questions about Jewish origin of partners intending to marry. But the goal of Carmi’s team was “to fill the gaps in our understanding of Ashkenazi Jewish early history.”
There are several non-destructive ways to obtain DNA from human remains, said Carmi, who also works as a consultant to an Israeli firm that helps clients trace their genetic roots.
“You can take an almost microscopic slice of bone and extract DNA in a solution, or put the entire bone in a solution and extract the DNA without drilling, without disturbing the dead. This opens the way to doing studies even without teeth,” he added.
His team found that the Erfurt community appeared to fit into two genetically distinct groups, descending either from Middle Eastern or European populations. This genetic variability no longer exists, Carmi said.
At the same time, Carmi said, the analysis found remarkable continuity in the local community, as well. “One third of the Erfurt individuals descended from one woman through their maternal lines,” he said, adding that evidence suggested that she lived between 1,000 and 2,000 years ago.
In a press statement, geneticist Reich of Harvard said the work “also provides a template for how a co-analysis of modern and ancient DNA data can shed light on the past. Studies like this hold great promise not only for understanding Jewish history, but also that of any population.”
The research team, with more than 30 scientists, included Hebrew University’s Shamam Waldman, a doctoral student in Carmi’s group, who performed most of the data analysis.

Brooklyn’s Park Slope Food Coop votes to boycott Israeli products
(JTA) — Two-thirds of the famed worker-owned grocery store in Brooklyn’s Park Slope voted Tuesday night in favor of a boycott of Israeli products. The vote came after a years-long battle that divided coop members and the Park Slope community.
Of the 6,772 votes cast at a meeting that lasted for hours, 67% voted in favor of the boycott, 31% voted against, and 2% abstained, according to immediate results of the vote viewed by JTA.
Nearly 7,000 out of the 16,000 members of the Park Slope Food Coop signed on to participate in the vote, where two ballot questions decided the fate of under a dozen Israeli products sold at the neighborhood spot. Now, those Israeli products will be removed from the shelves.
The Boycott, Divestment and Sanctions effort has been a hot issue at the Park Slope Food Coop for more than a decade. But since the October 7, 2023, Hamas attacks in Israel and the ensuing Gaza war, the coop’s stance on the sale of Israeli goods has become a flashpoint among its 16,000 members. Tuesday’s vote was so contentious that coop coordinators increased security measures around the coop itself and decided to hold the vote remotely.
Coop members first voted on a resolution lowering the required threshold to pass a boycott from a 75% supermajority of members to a simple majority of 51%. This vote passed 68% to 31%, with 1% abstaining.
Only after that passed did the group consider a resolution to boycott the sale of Israeli products. That resolution declared that, “Until Israel complies with international law, including by ceasing unlawful discriminatory practices in its treatment of Palestinians, the Coop will not sell goods produced in Israel (pre-1967 borders) or in Israeli settlements in the Occupied Palestinian Territory.”
The boycott will affect nine Israeli products, including a variety of bell pepper sold only in the winter, persimmons, olive oil, sesame products, Dorot frozen herb cubes and Osem Bamba, the popular Israeli peanut-flavored snack, according to Park Slope Food Coop Members for Palestine.
The advocacy group PSFC Members for Palestine first proposed a boycott in 2024; Coop4Unity, the anti-BDS group, was founded in 2024 to prevent that.
Tuesday’s meeting was moved entirely online to accommodate the size of the “unprecedentedly large” guest list and also for security reasons, coop staff announced in an email days before the vote.
“Staff, presenters, Chair committee and other members have all raised explicit concerns about their safety, attending the meeting in-person,” PSFC coordinators wrote in their email. “We cannot guarantee their security even if supplemental security measures are introduced. Therefore, the safest way forward is to limit attendance to all virtual.”
The market’s fight over BDS has even entered the Democratic primary election discourse in the coop’s congressional district of NY-10, in which two Jewish candidates are facing off.
Incumbent Rep. Dan Goldman condemned the vote in a statement to the Forward last week. “Everyone is free to criticize the Israeli government — which I do not hesitate to do — but joining a movement that was founded on the principle of the elimination of Israel will have no impact on the Israeli government or the Israeli economy,” Goldman said. “Instead, it only succeeds at shifting the responsibility for the Israeli government’s actions to American Jews — which is quintessential antisemitism.”
Goldman’s opponent, former New York City Comptroller Brad Lander, said he is not a member of the coop but would vote against the resolution if he were.
The rhetoric at the coop over the BDS effort has escalated in recent weeks. During an April meeting, a member stated that, “Jewish supremacism is a problem in this country.”
Jewish Community Relations Council CEO Mark Treyger had called for an investigation into the incident. Coop4Unity has also filed a state human rights complaint, alleging antisemitic and anti-Israel harassment at the market.
Ahead of Tuesday’s vote, Israel supporters rallied to stave off a boycott. The leadership of Park Slope synagogue Congregation Beth Elohim called on its more than 2,300 adult members to attend the general meeting and vote against the resolutions.
“This proxy war for the war between Israelis and Palestinians is now dividing our local community into two camps,” CBE’s Rabbi Rachel Timoner said during a sermon earlier this month. “Why is this petty, annoying fight in our neighborhood grocery store worth so much time and effort? Because it is part of something much larger. In the end, it is about antisemitism, a real and rising threat which ultimately carries existential danger both for Jews and for every society in which it takes hold.”
A group of progressive New York rabbis, however, wrote an open letter to the coop community condemning those who called the boycott “antisemitic.” The letter stated that not all the signatories endorsed the boycott.

Nearly half of young U.S. Jews want to replace Israel with binational state, poll find
Almost half of American Jews under 35 say the Israeli-Palestinian conflict should be solved by creating a single country in Israel, the West Bank and Gaza with a government elected by both Israelis and Palestinians, according to a poll conducted by the Jewish Voter Resource Center.
The findings signal a generational shift in U.S. support for a binational state in Israel, reflecting a core demand of anti-Zionist protests on college campuses and beyond — even as most major Jewish organizations classify calls for a single state as an expression of antisemitism.
“The growing disaffection of younger Jewish Americans from Israel is a direct consequence of the policies of Bibi Netanyahu and the way the American Jewish establishment has demanded an ‘Israel right or wrong’ loyalty,” said Jeremy Ben-Ami, president of J Street, the liberal advocacy group. “They’re reaping the harvest of seeds they planted — this is what you get.”
Ben-Ami pointed to the destruction of Israel’s war in Gaza, in which it killed an estimated 70,000 Palestinians and destroyed more than 80% of the enclave’s infrastructure, and growing violence by Jewish settlers in the West Bank, among other actions.
The data also adds to a growing debate over what share of Jews in the United States are Zionist, The Jewish Federations of North America began circulating data earlier this year that shows that around 90% of American Jews continue to support Israel’s existence as a Jewish and democratic state, even as only 37% label themselves “Zionist.”
The Jewish Voter Resource Center poll, released on Thursday, challenges these findings. Twenty-four percent of Jewish adults polled support a one-state solution to the conflict, according to the survey, nearly double the 13% who said they preferred a binational state just two years ago. While age breakdowns were not available for the 2024 poll, an American Jewish Committee survey in 2022 found that 23% of American Jews ages 25 to 40 supported a binational state.
Half of non-Orthodox Jews under 35 — 51% — support a binational state, according to the new poll.
The Jewish Federations of North America declined to comment.
This abrupt turn comes amid a transformation in how Americans view Israel — favorability toward Israel has plummeted among almost every demographic group since 2022 — that has extended to Jews. A Washington Post poll found that 61% of Jewish adults said Israel had committed war crimes against Palestinians in Gaza, while 39% said it was guilty of genocide.
The shift in public opinion also drives a deeper wedge between Israeli and American Jews. While many Jews in the U.S. have been alarmed by Israel’s conduct in Gaza following the Oct. 7 Hamas terrorist attack, Israeli Jews have expressed a sense of increased vulnerability, and some viewed the massacre as shutting down the possibility of Israel giving up control over the Palestinian territories or granting Palestinians equal rights.
A poll from Tel Aviv University last year found that only 15% of Israeli Jews supported a two-state solution, while 29% wanted to annex the West Bank and Gaza without offering citizenship to Palestinians living there. Only 1% of Israeli Jews supported “one binational state with civil rights.”
When asked in more detail about the possibility of a one-state solution, 3% of Israeli Jews said they would support it only if Palestinians were granted equal rights while 37% said they would support it if Palestinians were not given full rights.
Jeremy Pressman, who studies the Israeli-Palestinian conflict at the University of Connecticut, said that young American Jews have little experience of Israel as a vulnerable underdog, unlike older generations that witnessed the establishment of the state or its victory in the 1967 and 1973 Arab-Israeli wars.
Instead, they’ve largely come of age while Israel has been controlled by right-wing governments and have watched Israeli violence toward Palestinians on social media. “This creates a gap between the dominant Israeli Jewish understanding of the conflict and the center-left — or sometimes radical left — understanding of Jewish Americans,” Pressman said in an interview.
The Jewish Voter Resource Center, which is affiliated with the Jewish Democratic Council of America, polled 800 registered Jewish voters and the margin of error was +/- 3.5 percentage points and +/- 6.9 percentage points for Jews under 35.
Asher Kaplan Leba, a leader of the Massachusetts Synagogue Network on Israel/Palestine in Boston, said that many Jews had become disillusioned with a two-state solution as the Israeli government took steps that seemed to make it more difficult to implement, such as expanding West Bank settlements.
“It was my position for many years,” said Leba, 32. “But I don’t want to spend the rest of my adult life waiting for the authoritarian, ethno-nationalists in control of Israel — who I share no values with — to change.”

Candidate who vowed to imprison ‘American Zionists’ loses in Texas runoff
(JTA) — Sheriff’s deputy Johnny Garcia won the Democratic nomination Tuesday in Texas’ 35th Congressional District, defeating opponent Maureen Galindo following a race shaped by scrutiny over Galindo’s antisemitic rhetoric.
The runoff in the San Antonio race drew national attention after Galindo, a local housing activist and therapist, came under scrutiny for comments that included vows to turn a local immigrant detention center “into a prison for American Zionists” and claims that it was her “perception that Zionist billionaires run the world.”
Following Galindo’s surprise first-place finish in the march primary, national Democratic leaders and Jewish organizations condemned her rhetoric and urged voters to reject her candidacy, including Texas Senate candidate James Talarico, who revealed to JTA earlier this month that he would not back or campaign with Galindo.
The district, which stretches between San Antonio and Austin, was heavily affected by Republican redistricting this year, one of several factors that local political observers and Democratic Party leaders said contributed to Galindo’s earlier win.
The race also attracted outside spending, with Lead Left PAC, a newly launched super PAC apparently tied to a Republican donation platform, pouring over $900,000 on ads and mailers promoting Galindo. Last week, the Democratic Congressional Campaign Committee launched a $35,000 ad buy against Galindo, an unusual step for the DCCC to take against a Democratic candidate.
“Republicans just spent weeks and almost a million dollars propping up an antisemite, and they should be ashamed and embarrassed — it was a disgrace,” the president of the Democratic Majority For Israel PAC, Brian Romick, told JTA in a statement. “Tonight is a victory for the voters of TX-35, for the Democratic Party, and for every Democrat who believes that antisemitism has no home in our coalition.”
Romick told JTA Tuesday night that he believed the results of the runoff signaled that Democratic primary voters “aren’t going to elect antisemitic candidates, and in the districts that we need to win, pro-Israel candidates are our best bet.”
Garcia will now face Republican nominee Carlos De La Cruz, who defeated opponent John Lujan, in the Nov. 3 general election.
