Losing a Lost Tribe: Native Americans, DNA, and the Mormon Church

 For the past 175 years, the Latter-day Saint Church has taught that Native Americans and Polynesians are descended from ancient seafaring Israelites. Recent DNA research confirms what anthropologists have been saying for nearly as many years, that Native Americans are originally from Siberia and Polynesians from Southeast Asia. In the current volume, molecular biologist Simon Southerton explains the theology and the science and how the former is being reshaped by the latter. In the Book of Mormon, the Jewish prophet Lehi says the following after arriving by boat in America in 600 Wherefore, I, Lehi, have obtained a promise, that inasmuch as those whom the Lord God shall bring out of the land of Jerusalem shall keep his commandments, they shall prosper upon the face of this land; and they shall be kept from all other nations, that they may possess this land unto themselves (2 Ne. 1:9).

Simon and I were both faithful Mormons years ago, and at one point I was our local Stake Young Men President when Simon was his Ward Young Men President, and we worked together in our 'callings' here in England. Who would have thought that years later our paths would cross once again as authors and exMormons - me with my Mormon Delusion series and Simon back home in Australia exposing the DNA evidence concerning Mormon claims about Native Americans. Simon's work is academically sound and worthy of reading if you want to put Mormon claims to bed once and for all.

A great resource written by a former bishop and molecular biologist for those interested in what DNA can tell us about the origins of the native americans. DNA taken from native tribes across the western hemisphere show that the native tribes came to America from Asia - Siberia at least 10,000 years ago. No pre-columbian native american DNA has been found that can be traced to Semitic ancestors.

These discoveries, which confirm what anthropologists and archeaologists have long believed, probably let to the recent change in the new version of the Book of Mormon introduction. Previous versions of the BOM had stated that the Lamanites were the principle ancestors of the native Americans. The new version has been changed by the church to read that the Lamanites are 'among' the ancestors of the native Americans.

This book does a good job exposing some of the genetic problems with the claim made by the Mormon Church that a cluster of Ancient Hebrews described in the Book of Mormon are among the principle ancestors of the native inhabitants of North and South America today; however, this book fails to discuss the practically unfalsifiable claim that a very small group could have integrated themselves into a continent and culture that was mainly inhabited by an indigenous population that had previously populated the continent prior to their arrival. Finding the genetic markers to support this claim would be like looking for a needle in a haystack. This book also fails to point out the effects of genetic drift and genetic bottlenecking and how these evolutionary processes would increase the difficulty of ever finding the correct genetic markers to prove or disprove the possibility previously described.

Prepare yourself for statistical and DNA proof that the lost tribes of Israel DID NOT travel from the Middle East to Missouri as Joseph Smith had proclaimed. A very researched and thourough account of the Human Genome Project and the resistors of the truth in the Mormon heirarchy,

Outstanding book. If you believe that archaeology or anthropology supports the Book of Mormon, you're in for a real surprise here!

In fairness, I should warn any Mormon readers: This book will seriously challenge your faith.

A GENETICIST (AND EX-MORMON) EXAMINES THE SCIENITIFIC/HISTORICAL EVIDENCE

Simon G. Southerton is an Australian plant geneticist. He wrote in the Preface to this 2004 book, “The Mormon belief that native people in the Americas and Polynesia are largely descended from Israelites is fundamental to the Church of Jesus Christ of Latter-day Saints, the ‘LDS’ or Mormon church. In addition, Mormons believe that these wandering Hebrews, when they arrived in the New World were practicing Christians centuries before the birth of Christ. These views come from the sacred writings Mormons possess in addition to the Bible, in particular the Book of Mormon… scientists also form views about human origins and the routs our various ancestors took when they colonized the earth… I will try as best as I can to introduce readers to both sides and to offer my views on what I consider to be the inevitable conclusion to the matter.” (Pg. vii)

He continues, “In this book, I will use the moderating tone of third person references to both scientists and Mormons. Disinterested commentators are rarely sufficiently motivated to write, and I am no exception. Several years ago I encountered research into molecular genealogy that compelled me to compare what I thought I knew religiously with what I knew from my training in science. I now have strong opinions about the topic, which I will express freely… My wish is not to offend or to offer advice on matters of faith. But for … Mormons who believe American Indians and Polynesians are largely descended from ancient Israelites, the recent findings of science may compel them, as I was compelled, to re-evaluate their thinking.

“For the sake of disclosure, I was a fully active member of the Mormon church for almost 30 years. I served a 2-year Mormon mission, married in an LDS temple, and served in several teaching and leadership positions including two years as a bishop… Professionally I have spent most of my career researching in the field of molecular plant biology… Just as molecular biology helps researchers decode human origins, it is applied to other animals and to plants to unravel genetic relationships and evolutionary origins.” (Pg, viii)

He explains in Chapter 1, “Until 1978 the LDS Church denied the Mormon priesthood to Africans based on the authority of the Book of Abraham. Consequently African men would not hold callings in the church or serve on missions. More critically, their families were denied certain temple rites that Mormons believe bind marriages and families together for eternity and are essential for salvation. Mormonism’s institutionalized prejudice sparked some of the most severe criticism the church has faced… In 1978 in response to considerable public pressure, the church announced a policy reversal and began allowing all worthy male members of the church to hold the priesthood… The flexibility with which Mormon theology was able to adapt … is noticeable in the rewriting of a few scriptural passages to tone down the references to skin color. The phrase ‘white and delightsome’ found in the earliest editions of the Book of Mormon was changed in some cases… to ‘pure and delightsome.’ The concept of skin color being a sign of God’s displeasure is still evident… LDS scripture asserts that those who are ‘blessed’ with a white skin are favored because of what they did as spirits in a pre-earth life.” (Pg. 11-12)

He explains, “The Book of Mormon reports that Lamanites who were converted to the Lord and became reunited with the Nephites experienced a remarkable transformation in skin color (3 Nephi 2:14-16). Their dark-skin curse was lifted and they ‘became white like unto the Nephites.’ It was once believed in the church that modern-day Lamanites who embraced the Mormon gospel would become ‘white and delightsome’ just like their ancestors in Book of Mormon times.” (Pg. 40)

He reports, “The nautical exploits of Thor Heyerdahl had captured the public imagination, among whom Mormons proved to be his most enthusiastic disciples. At the time of Heyerdahl’s voyages in the pacific, they were widely publicized in the church, particularly among Polynesian members… Research confirming that ancestors of the Polynesians sailed out of Southeast Asia rarely catches the attention of Mormons, and scholars who champion this view remain largely unknown among church members… Heyerdahl stimulated considerable activity among Pacific scholars to more carefully and thoroughly analyze the available archaeological evidence. This research has largely reconfirmed the strong links between Polynesia and the Orient. The iconic status Heyerdahl holds among Mormons resulted largely from selective examination of evidence in support of LDS beliefs.” (Pg. 52-53)

He notes, “Two Mesoameican civilizations, the Olmec and Maya… have enthralled Mormon archaeologists… Mormon scholars frequently correlate the Olmec and Mayan civilizations with the Book of Mormon Jaredite (2200 to 600 BC) and Nephite (600 BC to AD 400) civilizations respectively, the two major groups about which the Book of Mormon is principally concerned.” (Pg. 83)

He summarizes, “The ancestors of Native Americans were Asians who unknowingly became the first Americans as they walked across Beringia over 14,000 years ago. The ancestors of the Polynesians were Asians who honed their considerable nautical skills among the islands of Southeast Asia before sailing out into the Pacific during the last 3,000 years. Regardless of coincidental cultural, linguistic, or morphological parallels with the Old World, the peoples of the Pacific Rim who met Columbus and Cook were not Israelites. They were descendants of a far more ancient branch of the human family tree that had existed thousands of years before the Israelite branch sprouted in existence.” (Pg. 130)

He explains, “The front line of defense for the church has been occupied since 1979 by scholars associated with FARMS, originally a privately funded organization, but predominately staffed by Mormons employed at BYU… Through FARMS, the church is now able to mobilize a considerable number of scholars to respond to critics of church positions, typically branded as ‘anti-Mormons.’ Book of Mormon apologetics have dominated the published work of FARMS… All FARMS research is published on the assumption that the historicity of the Book of Mormon need not be questioned… FARMS has proven to be highly successful in spurring an increase in the volume of scholarly investigations into the Book of Mormon… On volume alone, the critics have fallen far behind… Such scholarship rarely reaches externally reviewed journals. Consequently, FARMS remains an insular group that preaches to the choir.” (Pg. 148-149)

He points out, “One would expect cultures of the type described in the Book of Mormon to have left significant traces of their presence. For example, they were remarkably advanced in writing, agricultural practices, and widely used metallurgy. They possessed wheel technology, practiced Christianity, built Christian temples, and established cities with populations of tens of thousands. In contrast, the land adjacent to the Isthmus of Panama lacks the remains of any large, complex civilizations.” (Pg. 156-157)

He argues, “Another impetus for the restricted geography [view of the BOM] is the obvious fact that the Americas were widely inhabited thousands of years before the arrival of the Jaredites in 2200 B.C. The astounding array of cultures and languages encountered by early Europeans could not have originated from the Hebrew said to have been spoken by the Nephites and Lamanites of AD 400. The only plausible explanation for Mormon apologists is that the two groups of Semitic immigrants---the Lehites (Lamanites and Nephites) and Mulekites---occupied a restricted area in the Americas.” (Pg. 159)

He reports, “a radically new interpretation of Book of Mormon history has emerged among Mormon scholars. Many of them have questioned the widely held belief that present-day American Indians are Lamanites. Most LDS apologists now accept that the Americans were widely and heavily populated at the time the Lehites arrived on the continent. FARMS writers propose that while Lehi and his small group quickly dominated the native populations soon after they arrived in the New World, their own populations may never have become numerically significant… the shift from a macro-history of all ancient peoples of the continents of North and South America to a micro-history of a few people who lived somewhere in Mesoamerica corresponds with the exponential growth in secular research revealing an overwhelming connection to Asia. For all the criticism leveled at mainstream dogma, the thinking of Mormon scholars is now more aligned with their Gentile colleagues than the teachings of latter-day prophets.” (Pg. 163-164)

He points out, “The wheel, another technology familiar to Book of Mormon peoples, was never used in ancient America. A wheeled child’s toy has been advanced by some apologists as evidence of the existence of the wheel. Even if there were wheeled vehicles, there were no draft animals in America to pull them.” (Pg. 172)

He concludes with the DNA evidence: “In refuting claims that DNA findings challenge the historicity of the Book of Mormon, LDS scientists have advanced the idea that if one correctly understood the principles of population genetics, one would realize how improbable it would be to find evidence for an Israelite presence in the Americas… LDS scholars have come to the conclusion that the Jaredite and Nephite peoples comprised a very small part of the vastly larger, pre-existing populations and that those who still believe the whole hemisphere was the literal descendants of Lehi live among contemporary natives of the Americas, are simply wrongheaded and have made ‘incorrect interpretations of the [BOM] text.’ … [Some LDS scholars] argue that by using DNA technology, it would be virtually impossible to test the local colonization hypothesis, requiring that one discover remnants of a small lsraelite family after its absorption into the larger indigenous population 2,6000 years ago.” (Pg. 186-187)

This book will be of great interest to anyone studying the issues of DNA, the Book of Mormon, and Native Americans.

Why I read it.
I was probably in the 4th grade. I remember reading and being taught that scientists thought that Native Americans came to the American continents some 10,000 years ago, crossing a land bridge from northern Siberia (Asia). It was unfortunate that my teacher in school merely stated the proposition without explaining any of the science that led to the theory. And of course I was told at home that such wasn't scientific fact, just a theory made up for lack of a better explanation. In our household we knew the true origin of the Native Americans. Coming home from school was like stepping back to the right side of a protective curtain.

From well before those days, the LDS church fought an undeclared war with science over the origins of the Native Americans. In LDS circles, the science was most often called the 'theories of men', and with the help of apologists, good parents did their best to protect their families from theories that conflicted with revealed truth.

Over the years I read articles and books on the emerging science on human origins and migrations, but I never kept up with the evolving responses from Mormon apologists. Simon Southerton's book, Losing a Lost Tribe, brings the science and apologetics together in an excellent summary of the current state of the battle. I found it a compelling drama.

In response to DNA evidence (and a lack of archeological evidence) Book of Mormon apologists have formulated new explanations, but they now walk a knife's edge with their theories, often (and sometimes admittedly) undermining
-the literal, clear reading of Book of Mormon text, or
-the self-proclaimed purpose of the Book of Mormon, or
-the clear teachings of a long line of LDS authorities.

But why read about it?
For me, reading this book seemed a necessary completion of passage from my younger years -- a look back to see that the curtain was indeed gone.

Simon Southerton, a molecular biologist professionally and a former Mormon bishop, explores and explains the pickle the Mormon Church is in with its insistence the Book Of Mormon is a detailed history of the origin of native peoples of the Americas and Pacific Islands. Mormons are convinced these peoples derive from Jerusalem around 600 BC. DNA evidence of their claims is non-existent. Well researched. Well explained. Bravo for someone willing to look for truth above faith. Updated 10-6-21 to add: shortly after this book was published, the Mormon Church changed its title page to the Book Of Mormon, deleting the 200+ year original title page written by Joseph Smith, that claimed the book was the literal history of the Native American Indians and Pacific Islanders. Now it says “Another Testament of Jesus Christ.” Fascinating.

A very readable explanation of the genetic hurdle facing the BOM by a molecular biologist and former bishop. Considering the Meldrum drama currently unfolding, Southerton's comments on apologists are especially poignant.

In "Losing a Lost Tribe," Simon Southerton does a great job of giving an even-handed overview of the believing perspective, as well as an overview for why the believing perspective is untenable when confronted with scientific fact.

It’s sometimes hard to read something that forces you to confront beliefs you once held so dear, but it is good to gain perspective, too. It’s amazing how clear it is that there is zero evidence to support the Book of Mormon as anything but fiction.

Published 20 years ago (2004). Discusses the lack of DNA, archaeological, and geographical evidence to support traditional claims of the Book of Mormon as a history of people who migrated from Jerusalem to America and became the ancestors of Native Americans.

The author asserts that “The faith of most Latter-day Saints is anchored by an emotional, feeling based “knowledge” that the Book of Mormon is a true history of the Americas – a knowledge that is unencumbered be the facts.” He goes on to say, “For Mormons who choose to deepen their faith in the Book of Mormon through scholarship, learning about the limited archaeological evidence to support the book can be a shock.” But, as he points out in the following paragraph, most won’t even try to do that. “Few Mormons ever come face to face with research that threatens their traditional beliefs. The closest contact for almost all members is through second-hand accounts from church leaders or LDS apologists who tell them how scientists continue to get it wrong. There is a strong taboo in Mormonism that prevents most members from reading books that are suspected of being critical of the church or challenging to its doctrines. This, combined with the fact that most members follow their leaders without question, ensures that members are effectively immunized against anything that undermines their fundamentalist beliefs. Gentile scientists who discover uncomfortable truths are commonly suspected of being in cahoots with “anti-Mormons.”

He concludes, “It seems that among the obstacles facing the church, the real stumbling block is not the failure to find evidence for horses, metallurgy, or the wheel in the New World, or the fact that there is no evidence for a Hebrew influence in Mesoamerica, or the preponderance of Asian DNA among living Native Americans and Polynesians. The real challenge comes from a failure to openly confront the evidence and state what it means for the church, as well as a failure to accommodate the apologists, who themselves feel hemmed in by the church’s insistence that members believe tenets that are clearly untrue.”

Since the book’s publication, the LDS church (~2006) changed the wording of the Book of Mormon from “…and they are the principal ancestors of the American Indians.” to “…and they are among the ancestors of the American Indians.” The Church also published a “Gospel Topics Essay” (~2014) titled “Book of Mormon and DNA studies” in which they further backed away from the historicity of the Book of Mormon stating “Although the primary purpose of the Book of Mormon is more spiritual than historical, …” before delving into the alignment/lack of alignment of the book with science.

Losing a Lost Tribe: Native Americans, DNA, and the Mormon Church by Simon G. Southerton offers an insightful, clear, and compelling look at the intersection of science, history, and religion. Southerton, a former Mormon and geneticist, deftly tackles the controversial claims of the Mormon Church regarding the origins of Native Americans, particularly the idea that they are descended from ancient Israelites. What sets this book apart is its ability to present complex scientific concepts in a straightforward, easy-to-understand manner, making it accessible to readers with varying levels of knowledge about genetics or the Mormon faith.

The book's strength lies in its irrefutable scientific analysis. Southerton meticulously examines DNA evidence, explaining how it challenges long-held religious narratives about the peopling of the Americas. His clear explanations of genetics, combined with a respectful but firm critique of the Mormon Church's claims, offer a balanced and thought-provoking perspective. Southerton’s conclusions are backed by years of scientific research, making his case both credible and convincing.

For anyone interested in the intersection of faith and science, Losing a Lost Tribe is a must-read. It offers not only a deep dive into the genetic evidence but also a personal narrative of Southerton's own journey from belief to skepticism. Ultimately, the book provides readers with an undeniable scientific perspective that reshapes our understanding of Native American ancestry and the claims made by religious institutions.
