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.

‘Nobody Wants This’ star Adam Brody on Gaza: ‘Put me down as thinking it’s a genocide’
Adam Brody, the Jewish actor who plays a “hot rabbi” on the hit Netflix rom-com Nobody Wants This, called the war in Gaza a genocide in a new interview, making him one of just a few Jewish celebrities to speak out publicly against the Israeli campaign.
The comments came in an interview with GQ about Brody’s efforts canvassing for Democratic candidates in the upcoming midterms.
“Put me down as thinking it’s a genocide. Put me down as wanting a free Palestine,” he said. “It’s awful that it’s taken so much death and misery, but it does feel like it’s reaching a breaking point that it should have a while ago. I’m hopeful that another administration can really do some good and correct some of these policies that are helping that situation be as awful as it is.”
The claim of genocide in Gaza is heavily disputed. Several international bodies, human rights organizations and academic institutions have concluded Israel’s actions in Gaza since Oct. 7 fit the description, including a United Nations Commission of Inquiry. Other similar groups, like the International Court of Justice, have not applied the term.
Brody’s comments were surprising in part because he had previously kept his feelings about the war private, even as other leading Hollywood figures openly criticized it. He does not maintain a public social media presence, and he did not participate in pin-wearing campaigns or sign various petitions related to the war — an approach he indicated he might change going forward.
“I’m not wearing a pin, so I’m not inviting a certain question, and perhaps I should,” he said. “I really admire people who do. But 99% of what I’m asked about is about the show. I’m not trying to plead ignorance—here we are doing a political interview, so it makes sense that we wade into this territory—but I’ve never ducked a question, really, not a political question anyway.”
Brody — who came to fame in the 2000s as the teenager Seth Cohen on The O.C. — joins Hacks star Hannah Einbinder and Wallace Shawn (The Princess Bride) as perhaps the most high-profile Jewish actors to publicly call the war a genocide. Other Jewish entertainment figures, like Mandy Patinkin and The Zone of Interest director Jonathan Glazer, have criticized the war but stopped short of calling it a genocide.
Yet Brody’s comments are perhaps especially notable because of the character he plays on TV. In Nobody Wants This, Brody plays a rabbi dating a non-Jewish woman — introducing her to the beauty and foibles of Jewish faith and culture. Israel has been conspicuously absent from the show, with its creator, Erin Foster, saying she deliberately avoided geopolitics.
Season 3 of Nobody Wants This releases to Netflix October 22.

Why Mamdani remains focused on Israel as NYC mayor
When Israeli Prime Minister Benjamin Netanyahu spoke at the UN this week, New York City Mayor Zohran Mamdani was there — not in body, but in spirit, having condemned the Israeli prime minister and previously encouraged protests against him.
As a leader in the Jewish community, I know that many American Jews oppose Netanyahu’s government. But many also believe strongly that Israel’s survival as a Jewish homeland is critically important. They, therefore, feel boxed in by the mayor: compelled by conscience to oppose Israel’s leader and to condemn Mamdani’s repeated attacks on Israel’s existence, many of which they find offensive and dangerous.
Because of my previous work for Mayor Bloomberg, I am often asked by Jewish community members why this mayor so frequently puts them in this painful bind. The answer, I believe, lies in motivations worth understanding more clearly.
Of course, Mamdani’s focus on Israel seems partially motivated by principle. He clearly thinks Israel is illegitimate and opposes how it defends itself. I take him at his word that these convictions are sincere. But sincerity still does not explain his single-mindedness. A mayor willing to absorb this much political friction must see some benefit. But what?
To understand, let’s reexamine the 2025 election, often described as a “political tsunami.” The facts, however, are more complicated. Mamdani did defeat his closest opponent by nearly 10%, but in so doing he secured under 51% of the total vote – against a flawed and divided opposition. Viewed this way, his impressive margin seems less sweeping and much narrower.
More important than his electoral margin, though, is the coalition that produced it. His victory rested heavily on three blocs: self-identified very liberal voters; and Muslim and South Asian voters, who turned out in historic numbers. South Asian and Indo-Caribbean turnout, for example, rose 350% between 2021 and 2025, with 87% of South Asian votes going to Mamdani. Analyzing available data, I believe that, taken together, these three blocs accounted for well over 50% of all Mamdani votes.
What makes this coalition intriguing is that it consists of such strange bedfellows. The blocs differ sharply on many key local issues. On same-sex marriage, PRRI’s American Values Atlas found 33% support among Muslim-Americans in 2024, with support among very liberal Americans substantially higher. The divergence is similarly stark on policing, education, and many other policies.
In fact, it is hard to identify many things uniting these blocs besides this candidate: a skilled politician speaking the language of the left, while activating Muslim and South Asian voters just as Mayors Bloomberg and Koch activated Jewish voters and Mayors Adams and Dinkins activated Black voters.
Which brings us back to Israel.
When one barely ekes out a majority against flawed opponents, and one’s coalition is fundamentally misaligned, one must find ways to hold it together. To this end, Mamdani seems to be taking a page from Donald Trump. When Trump’s coalition buckles, he reaches for a “shiny distraction” — attacks on the press; trade wars; threatened invasions of Greenland. For Trump, the specifics are almost irrelevant; what matters is the theater of conflict and the distraction it produces.
For Mamdani, his Greenland is Israel.
Yes, it is a subject on which he holds sincere convictions. But, more importantly, it is one of few issues on which his coalition agrees. His relentless focus on Israel — to the exclusion of other worthy targets, including grave human rights offenders across South Asia and the Muslim world — is no accident. It is a political calculation allowing him to don the mantle of moral crusader while keeping his coalition on-side and united.
For those who believe Mamdani’s politics pose a danger to the Jewish community and want to slow his political momentum, this analysis yields two insights.
First, trying to persuade the mayor to soften his Israel attacks is unlikely to succeed. Doing so is not his inclination or in his political interests.
Second, and maybe more interestingly, Mamdani has a vulnerability that he seems to recognize – a fragile coalition. Allowing Mamdani to
make Israel his “shiny distraction” and engaging him on it plays his game. A different approach would be to defend Israel as-needed, but focusing efforts on pressing Mamdani to do his job – for example, elevating important issues, such as specialized high school admissions practices, on which his coalition happens to be divided.
The upshot? When smart politicians do things that seem politically risky, they usually see something others do not. Mamdani’s Israel focus offers a case-in-point. Those looking to respond should consider resisting the temptation to take the bait when possible. The wiser strategy is to engage under different rules: defending Israel when necessary, then pivoting to the difficult local issues from which Israel is meant to distract.
