The Book of Mormon’s antiquity has been questioned since its publication in 1830. Among LDS scholars today, one can find individuals on either side of the issue, some of whom think that it is time to separate acceptance of the book as scripture form belief in its ancient origin. Others doubt that the book accounts for all or even most Native Americans and therefore propose a limited geography in Central America. Both groups reject a literal reading and agree that Nephites and Lamanites actually never rode horses, traveled in chariots, used steel swords, raised cattle, or ate wheat or oats. FARMS has played a role in offering revisionist interpretations that seek to reconcile faith with science. But the DNA research may make this effort more difficult as the views of intellectuals and those of traditional Mormons continue to diverge.
