Jacob's Legacy: A Genetic View of Jewish History
Here are a couple of quotes from near the end of the article if you are pressed for time:
Genes, as Goldstein shows, are interesting to unravel and fun to study. But they are emphatically not destiny. We make existential choices about how we live and what we pass on as culture and values to our children.
The great and beautiful irony is that this ancient assessment of position and potential in society, this hostility to biological determinism and respect for free human choice and its consequences, is also at the core of modernity. It is refreshing to have this truth now affirmed, and in this context, by a geneticist.
