Scientists usually don’t call each other “liars” and “frauds.”

But that’s how Johns Hopkins University post-doctoral researcher Eran Elhaik describes a group of widely respected geneticists, including Harry Ostrer, professor of pathology and genetics at Yeshiva University’s Albert Einstein College of Medicine and author of the 2012 book “Legacy: A Genetic History of the Jewish People.”

For years now, the findings of Ostrer and several other scientists have stood virtually unchallenged on the genetics of Jews and the story they tell of the common Middle East origins shared by many Jewish populations worldwide. Jews — and Ashkenazim in particular — are indeed one people, Ostrer’s research finds.

It’s a theory that more or less affirms the understanding that many Jews themselves hold of who they are in the world: a people who, though scattered, share an ethnic-racial bond rooted in their common ancestral descent from the indigenous Jews of ancient Judea or Palestine, as the Romans called it after they conquered the Jewish homeland.

But now, Elhaik, an Israeli molecular geneticist, has published research that he says debunks this claim. And that has set off a predictable clash.

“He’s just wrong,” said Marcus Feldman of Stanford University, a leading researcher in Jewish genetics, referring to Elhaik.

The sometimes strong emotions generated by this scientific dispute stem from a politically loaded question that scientists and others have pondered for decades: Where in the world did Ashkenazi Jews come from?

The debate touches upon such sensitive issues as whether the Jewish people is a race or a religion, and whether Jews or Palestinians are descended from the original inhabitants of what is now the State of Israel.

Ostrer’s theory is sometimes marshaled to lend the authority of science to the Zionist narrative, which views the migration of modern-day Jews to what is now Israel, and their rule over that land, as a simple act of repossession by the descendants of the land’s original residents. Ostrer declined to be interviewed for this story. But in his writings, Ostrer points out the dangers of such reductionism; some of the same genetic markers common among Jews, he finds, can be found in Palestinians, as well.

By using sophisticated molecular tools, Feldman, Ostrer and most other scientists in the field have found that Jews are genetically homogeneous. No matter where they live, these scientists say, Jews are genetically more similar to each other than to their non-Jewish neighbors, and they have a shared Middle Eastern ancestry.

  • This is what the rockets over Israel and Gaza look like from space:
  • "Israel should not let captives languish or corpses rot. It should do everything in its power to recover people and bodies. Jewish law places a premium on pidyon shvuyim, “the redemption of captives,” and proper burial. But not when the price will lead to more death and more kidnappings." Do you agree?
  • Slate.com's Allison Benedikt wrote that Taglit-Birthright Israel is partly to blame for the death of American IDF volunteer Max Steinberg. This is why she's wrong:
  • Israeli soldiers want you to buy them socks. And snacks. And backpacks. And underwear. And pizza. So claim dozens of fundraising campaigns launched by American Jewish and Israeli charities since the start of the current wave of crisis and conflict in Israel and Gaza.
  • The sign reads: “Dogs are allowed in this establishment but Zionists are not under any circumstances.”
  • Is Twitter Israel's new worst enemy?
  • More than 50 former Israeli soldiers have refused to serve in the current ground operation in #Gaza.
  • "My wife and I are both half-Jewish. Both of us very much felt and feel American first and Jewish second. We are currently debating whether we should send our daughter to a Jewish pre-K and kindergarten program or to a public one. Pros? Give her a Jewish community and identity that she could build on throughout her life. Cons? Costs a lot of money; She will enter school with the idea that being Jewish makes her different somehow instead of something that you do after or in addition to regular school. Maybe a Shabbat sing-along would be enough?"
  • Undeterred by the conflict, 24 Jews participated in the first ever Jewish National Fund— JDate singles trip to Israel. Translation: Jews age 30 to 45 travelled to Israel to get it on in the sun, with a side of hummus.
  • "It pains and shocks me to say this, but here goes: My father was right all along. He always told me, as I spouted liberal talking points at the Shabbos table and challenged his hawkish views on Israel and the Palestinians to his unending chagrin, that I would one day change my tune." Have you had a similar experience?
  • "'What’s this, mommy?' she asked, while pulling at the purple sleeve to unwrap this mysterious little gift mom keeps hidden in the inside pocket of her bag. Oh boy, how do I answer?"
  • "I fear that we are witnessing the end of politics in the Israeli-Palestinian conflict. I see no possibility for resolution right now. I look into the future and see only a void." What do you think?
