Yes, of two faiths. According to this study, the genetic results suggest that the Arab/Muslim claims of having descended from Abraham through Ishmael are probably bogus, an example of Muhammed having tried to appropriate another religion's mojo for his designer religion (He later cut out certain phenotypes he had originally put in to attract Jews to it after they told him where to stick it. He went away mad, wrote anti-Judaism in, and he and his followers have been pissed at having been dissed ever since.)
Genetic evidence again links Jews to their ancient tribe By Judy Siegel
November 20, 2001
(November 20) - Genetic evidence continues to provide additional proof to the claims that the Jewish people are descended from a common ancient Israelite father: Despite being separated for over 1,000 years, Sephardi Jews of North African origin are genetically indistinguishable from their brethren from Iraq, according to The Hebrew University of Jerusalem.
They also proved that Sephardi Jews are very close genetically to the Jews of Kurdistan, and only slight differences exist between these two groups and Ashkenazi Jews from Europe.
These conclusions are reached in an article published recently in the American Journal of Human Genetics and written by Prof. Ariella Oppenheim of the Hebrew University (HU) and Hadassah-University Hospital in Ein Kerem.
Others involved are German doctoral student Almut Nebel, Dr. Marina Faerman of HU, Dr. Dvora Filon of Hadassah-University Hospital, and other colleagues from Germany and India.
The researchers conducted blood tests of Ashkenazi, Sephardi and Kurdish Jews and examined their Y chromosomes, which are carried only by males. They then compared them with those of various Arab groups - Palestinians, Beduins, Jordanians, Syrians and Lebanese - as well as to non-Arab populations from Transcaucasia - Turks, Armenians and Moslem Kurds.
The study is based on 526 Y chromosomes typed by the Israeli team and additional data on 1,321 individuals from 12 populations. The typing of the Jewish groups was performed at the National Genome Center at HU's Silberman Institute of Life Sciences.
The Fertile Crescent of the Middle East was one of the few centers in which the transition from hunting-gathering to permanent settlement and agriculture took place. Genetic studies suggest that migrating Neolithic farmers dispersed their technological innovations and domesticated animals from the Middle East towards Europe, North Africa and Southwest Asia.
Studies of Y chromosomes have become powerful tools for the investigation of the genetic history of males, since these chromosomes are transmitted from fathers to sons.
Surprisingly, the study shows a closer genetic affinity by Jews to the non-Jewish, non-Arab populations in the northern part of the Middle East than to Arabs. These findings are consistent with known cultural links that existed among populations in the Fertile Crescent in early history, and indicate that the Jews are direct descendants of the early Middle Eastern core populations, which later divided into distinct ethnic groups speaking different languages.
Previous investigations by the HU researchers suggested a common origin for Jewish and non-Jewish populations living in the Middle East. The current study refines and delineates that connection.
It is believed that the majority of today's Jews - not including converts and non-Jews with whom Jews intermarried - descended from the ancient Israelis that lived in the historic Land of Israel until the destruction of the Second Temple and their dispersal into the Diaspora.
The researchers say that a genetic analysis of the chromosomes of Jews from various countries show that there was practically no genetic intermixing between them and the host populations among which they were scattered during their dispersion - whether in Eastern Europe, Spain, Portugal or North Africa.
A particularly intriguing case illustrating this is that of the Kurdish Jews, said to be the descendants of the Ten Tribes of Israel who were exiled in 723 BCE. to the area known today as Kurdistan, located in Northern Iraq, Iran and Eastern Turkey. They continued to live there as a separate entity until their immigration to Israel in the 1950s. The Kurdish Jews of today show a much greater affinity to their fellow Jews elsewhere than to the Kurdish Moslems.
And so Yasser, as Abraham would no doubt say to you (quoting Phil Collins), "You're no son, you're no son, you're no son of mine."
