![]() מה קרה כאן?ARBEL חבל ,רציתי שהוא יראה את ההודעה שלי, בכל אופן לאשכנזים(אני חצי אשכנזי) יש בדיוק אותם שורשים כמו לספרדים/מזרחים,וכל המחקרים הגנטים מראים שהם יותר קרובים לאוכלוסיה באיזור לבנון ולסורים/פלסטניאים יותר מאשר לאוכלוסיה הלא יהודית במדינות שלהם באירופה, יש טונות של מחקרים שעושים את המיפוי על זה על פי DNA ו-y chromosome וזה די ברור שהקשר בין אשכנזים לאירופה הוא אך ורק תפוצתי ואולי תרבותי וכמעט ולא גנטי/גזעי.במקרים הכי גבוהים אשכנזים זהים עד ל-50% לאוכלוסיית אירופה אבל זה גם עם הרבה עירבוב.
אשכנזים יותר קרובים גנטית לאוכלוסיה באיזור מאשר לאירופאים,זה ידוע, ואכן האשימו אותם כזרים באירופה מסיבה זאת(למרות שלא היו אז מחקרי DNA). לכן כל מי שחי בסרט, יכול להפסיק, וזה כולל את ההוא שלא ראיתי מה הוא כתב נגד ספרדים. מדובר בסה"כ על יהודים מהמזרח התיכון שגורשו והתפצלו עקב כיבושים זרים,בעיקר הרומי. -------------------------------------------------------- Genetically speaking, Jews aren't being assimilated to any significant degree, says a researcher at the University of Arizona. Michael F. Hammer, an associate researcher in the Division of Biotechnology at the Arizona Research Labs, is the lead author of a new study, reported in the May 9 issue of the "Proceedings of the National Academy of Sciences," that suggests the Diaspora - the dispersion of Jews throughout the world - has not had a strong effect on the genetic link among Jewish men. The study, conducted by an international team from the United States, Europe, South Africa and Israel, shows that Jews are closely related to their Arab neighbors. "We saw such a strong signal of a Middle-Eastern origin, it was kind of surprising," Hammer says. Hammer says other studies have been conducted on Jewish genetic links, but the results often have been contradictory, resulting in disputes over Jewish origins. "Our work definitely refutes a lot of that discussion of alternate origins for Jewish populations," Hammer says. "It shows that we really are a single ethnic group coming from the Middle East. Even if you look like another European with blue eyes and light skin, your genes are telling that you're from the Middle East." http://www.jewishaz.com/jewishnews/000519/study.shtml ================================= Efforts to identify the origins of Ashkenazi Jews through DNA analysis began in the 1990s. Like most DNA studies of human migration patterns, these studies have focused on two segments of the human genome, the Y chromosome (inherited only by males), and the mitochondrial genome (DNA which passes from mother to child). Both segments are unaffected by recombination. Thus, they provide an indicator of paternal and maternal origins, respectively. A study of haplotypes of the Y chromosome, published in 2000, addressed the paternal origins of Ashkenazi Jews. Hammer et al[13] found that the Y chromosome of some Ashkenazi and Sephardic Jews contained mutations that are also common among Middle Eastern peoples, but uncommon in the general European population. This suggested that the male ancestors of the Ashkenazi Jews could be traced mostly to the Middle East. http://en.wikipedia.org/wiki/Ashkenazi#DNA_clues ================================== Figure:Relatedness of Jewish and non-Jewish populations based on Y chromosomal haplotypes. Virtually all Jews came from the Middle East as evidenced by the clustering of their Y chromosomal haplotypes between Jewish groups and between Jews and non-Jewish Middle Easterners." http://www.med.nyu.edu/pediatrics/ge...h_origins.html =================================== According to several other studies, Palestinians and Jews are genetically closer to each other than either is to the Arabs of Arabia or to Europeans [5]. A study of congenital deafness identified an allele limited to Palestinian and Jews of Ashkenazi origin (those who lived in Europe in recent centuries), suggesting a common origin http://hnn.us/blogs/entries/12334.html ================================= Looking at other populations, the Technion team found that some people in Egypt, Arabia and the Levant also carried the set of mutations that defines one of the four women. They argue that all four probably lived originally in the Middle East. A study by Michael Hammer of the University of Arizona showed five years ago that the men in many Jewish communities around the world bore Y chromosomes that were Middle Eastern in origin. This finding is widely accepted by geneticists http://www.nytimes.com/2006/01/14/science/14gene.html =================================== The finding of a common set of genetic markers in both Ashkenazi and Sefardi Kohanim worldwide clearly indicates an origin pre-dating the separate development of the two communities around 1000 C.E. Date calculation based on the variation of the mutations among Kohanim today yields a time frame of 106 generations from the ancestral founder of the line, some 3,300 years, the approximate time of the Exodus from Egypt, the lifetime of Aharon HaKohen. Professor Hammer was recently in Israel for the Jewish Genome Conference. He confirmed that his findings are consistent that over 80 percent of self-identified Kohanim have a common set of markers. Wider genetic studies of diverse present day Jewish communities show a remarkable genetic cohesiveness. Jews from Iran, Iraq, Yemen, North Africa and European Ashkenazim all cluster together with other Semitic groups, with their origin in the Middle East. A common geographical origin can be seen for all mainstream Jewish groups studied. This genetic research has clearly refuted the once-current libel that the Ashkenazi Jews are not related to the ancient Hebrews http://www.cohen-levi.org/jewish_gen..._tradition.htm ================================== |
