DNA and the Book of Mormon: What the Science Says and Why the Church Changed Its Story

For decades, The Church of Jesus Christ of Latter-day Saints taught with absolute certainty that Native Americans were the primary descendants of Lehi, a Jewish family who sailed from Jerusalem around 600 BC and populated the Americas. This doctrine was foundational, taught in missionary trainings, printed in official Book of Mormon introductions, and reinforced from the pulpit. Then, in 2006, the Church quietly altered the Book of Mormon's introduction, removing the word "principal" from the phrase describing Lamanites as ancestors of American Indians. Few members noticed. Many missionaries continued teaching the old narrative. But the change signaled something profound: DNA science had forced a reckoning that the Church could no longer avoid.

Today, the question of DNA and the Book of Mormon remains one of the most significant challenges to the historicity of the text, and one that exposes a pattern of narrative revision when empirical evidence contradicts longstanding claims.

Background: From Doctrine to Difficulty

For more than a century, the Book of Mormon's account of pre-Columbian America was presented as historical fact. Church leaders, including Spencer W. Kimball, stated without equivocation that Native Americans descended from Middle Eastern origins, not Asian populations. The 1981 Book of Mormon introduction declared them the "principal ancestors" of the indigenous peoples. This wasn't presented as theological metaphor or cultural narrative; it was stated as verifiable history backed by scripture.

The introduction itself was never claimed to be revelatory text or "from the plates." Yet it carried institutional weight, shaping how millions of members, especially missionaries serving in Latin America and among Native American communities, understood the relationship between the Nephite record and indigenous peoples they encountered.
