Who says this article does need DNA section is nuts! 

 The jews used the semitic right of return in 1950 to give immigration nationality certificates to what became the citizens of Israel on the basis that they are descendents of the Semites ( descendents of Abraham of the Bible, descendents of The Ancient Israelites who lived in Palestine pre 120AD , that their ancestors were citizens of the area in ancient times, any or one of the above). 
 The DNA studies prove that Jews ( sephard Mizrahi and Ashkenazim)  are not descendents of the ancient Israelites( their ancestors never set foot in the Holy Land or near it) using the three types of DNA ( Y chromosome mtDNA and Autosomal tchromosomes) all theree testings found the jews alien to the area and their haplogroups (Y DNA, mtDNA) and Autosomal SNPs are originated in areas far away from the middle East and never been to it in the past. 
 (Now if you don't have something you can not give it , right?) 
 The current jewshave no ancestry to a man ( abraham or otherwise)  who lived in Palestine and his descendents or adherents LIVED in that Area) so even if spiritual ancestry does not exist ( claiming that a pool of different people claimed Israelite status still does not fly either)
