Legacy: A Genetic History of the Jewish People
By Harry Ostrer
Oxford University Press, 288 Pages, $24.95
In his new book, “Legacy: A Genetic History of the Jewish People,” Harry Ostrer, a medical geneticist and professor at Albert Einstein College of Medicine in New York, claims that Jews are different, and the differences are not just skin deep. Jews exhibit, he writes, a distinctive genetic signature. Considering that the Nazis tried to exterminate Jews based on their supposed racial distinctiveness, such a conclusion might be a cause for concern. But Ostrer sees it as central to Jewish identity.
“Who is a Jew?” has been a poignant question for Jews throughout our history. It evokes a complex tapestry of Jewish identity made up of different strains of religious beliefs, cultural practices and blood ties to ancient Palestine and modern Israel. But the question, with its echoes of genetic determinism, also has a dark side.
Geneticists have long been aware that certain diseases, from breast cancer to Tay-Sachs, disproportionately affect Jews. Ostrer, who is also director of genetic and genomic testing at Montefiore Medical Center, goes further, maintaining that Jews are a homogeneous group with all the scientific trappings of what we used to call a “race.”
For most of the 3,000-year history of the Jewish people, the notion of what came to be known as “Jewish exceptionalism” was hardly controversial. Because of our history of inmarriage and cultural isolation, imposed or self-selected, Jews were considered by gentiles (and usually referred to themselves) as a “race.” Scholars from Josephus to Disraeli proudly proclaimed their membership in “the tribe.”
Ostrer explains how this concept took on special meaning in the 20th century, as genetics emerged as a viable scientific enterprise. Jewish distinctiveness might actually be measurable empirically. In “Legacy,” he first introduces us to Maurice Fishberg, an upwardly mobile Russian-Jewish immigrant to New York at the
fin de siècle. Fishberg fervently embraced the anthropological fashion of the era, measuring skull sizes to explain why Jews seemed to be afflicted with more diseases than other groups — what he called the “peculiarities of the comparative pathology of the Jews.” It turns out that Fishberg and his contemporary phrenologists were wrong: Skull shape provides limited information about human differences. But his studies ushered in a century of research linking Jews to genetics.
Ostrer divides his book into six chapters representing the various aspects of Jewishness: Looking Jewish, Founders, Genealogies, Tribes, Traits and Identity. Each chapter features a prominent scientist or historical figure who dramatically advanced our understanding of Jewishness. The snippets of biography lighten a dense forest of sometimes-obscure science. The narrative, which consists of a lot of potboiler history, is a slog at times. But for the specialist and anyone touched by the enduring debate over Jewish identity, this book is indispensable.
“Legacy” may cause its readers discomfort. To some Jews, the notion of a genetically related people is an embarrassing remnant of early Zionism that came into vogue at the height of the Western obsession with race, in the late 19th century. Celebrating blood ancestry is divisive, they claim: The authors of “The Bell Curve” were vilified 15 years ago for suggesting that genes play a major role in IQ differences among racial groups.
