At the heart of Jewish tradition lies the haunting mystery of the Lost Tribes of Israel. Ever since their defeat and banishment by the Assyrians in 722 BC., the Lost Tribes fate has inspired countless claims to Jewish ancestry by groups scattered on every continent. But now, surprisingly, new advances in genetics are dispelling myth and fantasy, and raising a curtain on the forgotten reality of the dispersal that happened so many centuries ago. This story will follow the first attempt to use the new tests to investigate a seemingly improbable African candidate for a Lost Tribe. It will dramatize a scientific quest that leads from the gene labs of London to the remote bush country of Zimbabwe and the lunar-like desert wilderness of southern Yemen.
