(11.08.2010) What is the essence of Jewish identity? Is it revealed in the choices we make, like giving tzedakah or observing the Sabbath, or is it in our genetic code? Is it a matter of faith, or a matter of heritability? Is it something we can choose, or is it a biological imperative embedded in nearly every cell of our body?

New genetic research, published as a paper titled “Abraham’s Children in the Genome Era” in the June issue of The American Journal of Human Genetics, highlights the strong genetic bonds both within and among Jewish communities around the world, their distinctiveness vis-à-vis the populations among which they have dwelled, and their links to the Middle East.
