Prolegomena to the DNA Articles

Prolegomena to the DNA Articles

Daniel C. Peterson

The quotation from Hugh Nibley that serves as the epigraph for my overall introduction
to this number of the FARMS Review bears repeating. “The normal way of dealing
with the Book of Mormon ‘scientifically,'” he wrote in 1967,
“has been first to attribute to the Book of Mormon something it did not
say, and then to refute the claim by scientific statements that have not been

Thirty-seven years later, Professor Nibley’s words still ring true.

The Book of Mormon mentions the migration of three small colonies from the Old
World to the New. Two of them consisted of Israelites who migrated to the Americas
soon after 600 B.C. One of these is described rather extensively; of the other,
we are told virtually nothing.2 The third migration, much earlier, originated
in Mesopotamia.

In his 2002 essay “Lamanite Genesis, Genealogy, and Genetics,” Thomas
Murphy argues that, since evidence from current scientific studies of molecular
DNA has been interpreted as showing an almost exclusively Asiatic genetic inheritance
for Native Americans, the Book of Mormon is almost certainly not true, and that,
accordingly, its claims to historicity should be abandoned.3 “So far,”
notes Murphy, “DNA has lent no support to the traditional Mormon beliefs
about the origins of Native Americans. Instead, genetic data have confirmed that
migrations from Asia are the primary source of American Indian origins.”4
“To date,” he says, drawing upon the published research of geneticists
pursuing entirely unrelated research goals and pressing it into service for what
has clearly become a personal crusade against the doctrine and ethos of the Church
of Jesus Christ of Latter-day Saints, “no intimate genetic link has been
found between ancient Israelites and indigenous Americans.”5

As Murphy and his fellow DNA-inspired critics depict the situation, however,
instead of taking the rational course of abandoning belief in historical Nephites
and Lamanites, some Latter-day Saint scholars now offer desperate revisionist
explanations. These include the idea that events in the Book of Mormon occurred
in a limited region of Mesoamerica and that Native Americans, or Amerindians,
whom Latter-day Saints have associated with the Lamanites, are not exclusively
Israelite but likely include among their ancestry those of other origins. These
explanations, the critics argue, contradict both the revelations of Joseph Smith
and long-held traditional views, even authoritative doctrines, about the Book
of Mormon.

Still, in a just-published article in Dialogue, Thomas Murphy claims
that defenders of the Book of Mormon are slowly, inexorably, being dragged
by the sheer force of reality and science toward his own position. According
to Murphy,

An apparent consensus on some central issues of debate about the Book of
Mormon appears to be emerging. Most Book of Mormon scholars today, including
those associated with FAIR and FARMS, reject a literal reading of the Book
of Mormon and “agree that Nephites and Lamanites never actually rode horses,
traveled in chariots, used steel swords, raised cattle, or ate wheat.” We
basically agree that the English text of the Book of Mormon does not accurately
describe the flora and fauna of ancient America in Central America or elsewhere.
We agree that the population growth attested in the Book of Mormon is mathematically
impossible for groups of the size and make-up described in the text and that
the descriptions of distances traveled in the scripture are not consistent
with a population that spread to “cover the face of the whole earth” on the
American continents “from the sea south to the sea north, from the sea west
to the sea east” (see Hel. 3:8). We agree that ethnonyms like Lamanite
from the Book of Mormon can have social and political meanings, in addition
to genealogical ones. We have reached a virtual consensus that the traditional
interpretation of the Book of Mormon as the history of the American Indians
has been thoroughly discredited by the discoveries of anthropology, biology,
and history. Thus, we would seem to agree that the teachings about Israelite
and Lehite ancestry of American Indians espoused by every LDS prophet since
Joseph Smith must necessarily be disregarded as incorrect.6

Intriguingly, though, this supposed consensus is (excepting a brief allusion to
Helaman 3:8) expressed entirely in the language of Thomas Murphy. Not a single
footnote connects Murphy’s assertions to any publication of either FAIR
or FARMS. Even the passage that Murphy cites, according to which his opponents
“agree that Nephites and Lamanites never actually rode horses, traveled
in chariots, used steel swords, raised cattle, or ate wheat,” quotes nobody
at either FAIR or FARMS. Instead, the quotation comes from an earlier essay by
Thomas Murphy himself, in which—much in the manner of the Idaho-based anti-Mormon
James Spencer—he speaks for his targets, who evidently cannot be relied
upon to say the things that they’re supposed to say.7 It is rather like
a chess game in which Murphy makes his opponent’s moves for her. Employing
such a technique, and given enough time and practice, he is quite likely to win
many of his matches. Consensus is typically easier to achieve when one is attempting
to persuade one’s own very eager self.

Refreshingly, the following five review essays represent the authentic opinions
of Latter-day Saint scientists and scholars as they actually appear in a genuine
publication of the Foundation for Ancient Research and Mormon Studies.8

In the first, entitled “Detecting Lehi’s Genetic Signature: Possible,
Probable, or Not?” David A. McClellan offers a challenging but essential
basic overview of the biology relevant to serious discussion of questions involving
DNA. The arguments advanced by Thomas Murphy and his allies plainly assume that
contemporary DNA studies are capable of either confirming or disproving the presence
of an element of Israelite ancestry in Native American roots. In fact, Murphy
attributes the same assumption to those whose position he is attacking. “Researchers
associated with the Foundation for Ancient Research and Mormon Studies (FARMS),”
he writes, “have rejected hemispheric models of the Book of Mormon but still
express ‘confidence in an Israelite genetic presence in Central America
and perhaps as far away as Arizona to the north and Colombia to the south.'”
And yet, Murphy suggests in the next sentence, the hopes of these unnamed FARMS
researchers appear doomed to disappointment: “I have found no genetic research,”
he says, “to support this expectation.”9

Once again, though, while he seems initially to be quoting a hope actually expressed
by FARMS researchers, it turns out that Murphy is really only citing himself,
speaking on their behalf.10 But David McClellan, who, unlike Thomas Murphy, is
an actual scientist actually specializing in human genetics and who, now, has
actually written for FARMS, does not expect to find “an Israelite genetic
presence in Central America and perhaps as far away as Arizona to the north and
Colombia to the south.” (They just don’t make straw men like they
used to.) McClellan points out that proper interpretation of Native American population
genetic data in the context of Latter-day Saint claims about ancient migrations
to the Americas by a few families from the Middle East requires a preliminary
understanding of several fairly complex concepts, including scientific method,
basic genomics and genetics, molecular evolution, population genetics, and genealogical
inference from molecular data. His essay seeks to outline these concepts in layman’s
terms and to evaluate the current status of Native American genetic data in light
of these concepts in order to evaluate the plausibility of the Book of Mormon
story line. McClellan’s general conclusion is that, although it may be possible
to recover the genetic signature of a few migrating families from 2,600 years
ago, it is not probable. However, the data suggest that there has been a trickle
of gene flow to the Americas from non-Asiatic source populations. Though far from
verifying or proving the Book of Mormon, these data do allow for the plausibility
of its story line.

In “Nephi’s Neighbors: Book of Mormon Peoples and Pre-Columbian Populations,”
Matthew Roper addresses the assumption, emphatically imputed to the Church of
Jesus Christ by its critics, that the peoples of the Book of Mormon were the only
inhabitants of the pre-Columbian New World and, thus, inescapably the sole ancestors
of the Amerindians. Roper’s essay calls attention to a deeply problematic
aspect of the DNA discussion thus far, a discouraging problem scarcely restricted
to this recent dispute over Amerindian genetics: All too often, rather than addressing
what the authoritative scriptural texts actually say, critics draw upon popular
belief and tradition to construct a version of Mormonism that, in their depiction,
resembles a sand castle beleaguered by the rising tide of scholarship and science.
Clearly, though, if any test of its claims is to be fairly conducted, the text
of the Book of Mormon itself, and not tradition or external commentary on it,
is and must remain primary. In fact, contrary to the charge that the rise of the
limited geographical view of the Book of Mormon is a recent and rather pathetic
response to scientific difficulties, many close students of latter-day scripture,
including prominent church leaders, have long recognized the overwhelming likelihood
that contemporary Native American peoples represent a blending of various groups
descended from a variety of ancestors in addition to Lehi and Sariah. Given this
complexity and the extremely limited picture that contemporary genetics offers
of our distant ancestral tree, it is unreasonable to insist that DNA studies alone
can prove or disprove an Israelite connection. If Latter-day Saints are not obliged
to attribute every Amerindian gene to Jaredites, Lehites, and Mulekites, however,
the purported DNA case against the Book of Mormon loses most if not all of its

In the third essay, “Swimming in the Gene Pool: Israelite Kinship Relations
and Ancestry,” Matthew Roper investigates the nature of the people of ancient
Near Eastern Israel and of Lehite Israel as described in the Book of Mormon, illustrating
the complexity of kinship and tribal lineage terminology among the Israelites
and those who were affiliated with them. Critics wishing to demonstrate that Native
American populations do not have Israelite roots need to establish the genetically
salient characteristics of an ancient Israelite source population. Yet when one
examines the nature of ancient Israel as described in the biblical account and
as it is known through later history, the fact soon becomes clear that Israel
was never a biologically homogenous entity, so that it is far from obvious what
an ancient Israelite genetic marker would look like. Similarly, when we examine
the text of the Book of Mormon, it becomes apparent that Lehite Israel is not
confined to biological descendants but also includes many others of several origins
who, under varying conditions and circumstances, came to be numbered with Israel.
Roper demonstrates that the approach taken to this issue by the critics, thus
far at least, has been simplistic and strikingly unnuanced.

Roper’s “Swimming in the Gene Pool” and the fourth essay—
“Elusive Israel and the Numerical Dynamics of Population Mixing,”
by Brian Stubbs—also offer independent discussions of the complex nature
of population dynamics and the factors that lead, surprisingly quickly, to extensive
literal kinships among large populations and the dissemination of a distinct group
into the mainstream population. Even a fairly low rate of intermarriage can transform
a once homogenous group within relatively few generations. Here it is important
to note what the essays published in this number of the FARMS Review and, recently,
in the Journal of Book of Mormon Studies are not arguing: To recognize that the
genetic contribution of Lehi or Sariah more than a hundred generations ago is,
very probably, unrecognizable at this distance is not necessarily to say that
the Lehi colony is genetically extinct and certainly does not deny the possibility
(and perhaps even the likelihood) that Lehi and Sariah figure among the biological
ancestors of most, if not all, of today’s Amerindians. As Thomas Murphy
himself has admitted, “One can have descendants who do not carry particular
genetic markers. For example, women do not carry their father’s Y chromosome.
Thus, one’s genetic markers can go extinct even though one has descendants.”11

In the fifth essay, “The Charge of ‘Racism’ in the Book of Mormon,”
John Tvedtnes relies on passages from the Book of Mormon to argue against the
culturally fashionable and politically damaging accusation that the text—and
therefore, presumably, Latter-day Saint belief in it—is racist. He acknowledges
that some Nephites were ethnocentric or racially prejudiced, for which they were
criticized by certain of their own prophets. He further differentiates the “curse”
of the Lamanites (being cut off from God on account of disobedience) from the
“mark” of a “skin of blackness” and notes that despite
the “curse” and “mark,” the Nephites consistently considered
the Lamanites to be their “brethren.”

Finally, just as it is important to grasp what these essays are not saying, it
is essential to understand what they are not purporting nor even attempting to
accomplish. Some critics have pointed out that Latter-day Saint defenses on the
issue of Amerindian DNA and the Book of Mormon have, thus far, sought only to
demonstrate that DNA analysis has not proven the Book of Mormon false, and that,
accordingly, it is still intellectually permissible to believe that there was
indeed a historical Lehi; no particular effort has been made, in these defenses,
to indicate why belief, even if it can still be maintained, might be preferable
to nonbelief. In this, they are correct. To the best of my knowledge, no serious
Latter-day Saint scholar or scientist contends that, to date, research on Amerindian
DNA provides significant affirmative support for the Book of Mormon.

Such critics go considerably too far, however, when they then invoke the principle
of parsimony, or the famous “razor” associated with William of Ockham,
to contend that Latter-day Saints should conclude that the Book of Mormon is nineteenth-century
frontier fiction because that is the simplest explanation consistent with the
apparent invisibility of Sariah’s mitochondrial DNA among today’s
Native Americans. Everything depends upon which evidence is determined to be relevant,
upon how widely the evidentiary net is cast. A spectator at a New York Yankees
baseball game a few generations ago might well have seen Babe Ruth go down swinging
several times in the course of a single nine-inning performance. He might pardonably
have concluded, if this was his first and only exposure to the home-run king,
that the Babe was a terrible hitter. He could even, with a bit of research, have
demonstrated that Babe Ruth consistently struck out at a very high rate. But,
obviously, his overall verdict would have been spectacularly wrong, for the simple
reason that his data sample was too small and too narrowly defined.

It is no valid criticism to observe that, at any given moment in a game of American
football, one team is concentrating on defense rather than on offense or that,
in formal debating, one side is arguing the affirmative and one side merely the
negative. Anybody familiar with the rules of football understands that the teams
will alternate their focus from defense to offense and back again many times in
the course of a single game. Both offense and defense are useful, even essential.
To use another sports image, it makes little sense to complain that a star soccer
goalie never makes points for his own team but merely prevents the other side
from scoring. That’s his job. The point total run up by careful students
of the Book of Mormon over the past few decades—a very impressive performance,
in my opinion—has been scored on the basis of other issues, such as the
impressive testimonies of the eleven witnesses (still not seriously countered
by any critic), chiastic literary structures, discoveries along the Arabian incense
trail, Hebraisms, unexpectedly accurate echoes of preexilic Israelite religious
culture, and many more topics that have been abundantly treated in hundreds of
publications. These matters must also be weighed and evaluated when applying Ockham’s
razor. On the issue of Amerindian DNA, by contrast, faithful Latter-day Saint
scientists and scholars do not believe that the current state of the research
permits a score for either side; indeed, they tend to expect that it never will.
Given the grossly inflated claims of the Book of Mormon’s critics on this
issue, these careful and scientifically grounded defenses do precisely what they
needed to do: They pop the balloon.

    the Book of Mormon

    passages are actually quite cautious and reserved; they scarcely justify Murphy’s
    assertion. Sorenson and Hamblin both minimize the overall importance, for discussions
    of the Book of Mormon, of literal biological kinship; Hamblin says absolutely
    nothing about the prospects, one way or the other, of finding relevant modern
    genetic evidence, while Sorenson acknowledges that it might someday be possible
    to do so but doesn’t think the matter at all significant. Murphy’s
    summary statement that, “like Hamblin,” Sorenson “expresses
    optimism that Lehite genes . . . may eventually be found” (Murphy, “Lamanite
    Genesis, Genealogy, and Genetics,” 62) is fundamentally misleading. Compare
    the case discussed on pages xxxix–xl in the introduction to this number
    of the Review, in which Murphy misrepresents both the work of Scott Woodward and
    an article in the Salt Lake Tribune, creating exaggerated, if not wholly fictional,
    Mormon expectations of finding “Lamanite DNA.”
