Edited sentence: A Jewish connection, tested for using Y Chromosomes, is most apparent among those who claim to be "cohanim" (of priestly descent).A migration similar to that described in the Book of Mormon took place with a few tribes of Jewish origin migrating to Africa at times similar to Book of Mormon times - see Lemba people.Genetic study of Lemba people revealed that despite heavy assimilation with local black population they still have many genetic markers which suggest Jewish descent.In response to criticism regarding Amerindians' lack of these genetic attributes, LDS scholars have said that there is no indication that descendants of Levi were among Lehi's group, making the existence of these specific haplotypes unreasonable.It is also noted by LDS researchers that another factor affecting genetic diversity of New World inhabitants is the fact that 90% of the population died as the result of disease introduced by the Spaniards after their arrival.Some say that genetic evidence does not support the hypothesis that American Indians are descendants of Israelites, while others disagree.The Lemba, on the other hand have maintained traditions of being descended from Cohen, or Levites, making it easier to test for their genetic inheritance.The Limited Geography Model, published in the official church magazine The Ensign in 1984, is supported by most LDS scholars and includes the proposition that other unknown peoples were present in the New World from whom indigenous Americans could also be descended.They also say that it is more difficult to test Native American DNA for Israelite heritage since traditions of Jewish descent do not currently exist
