==Criticism==
+
*[http://www.mediawiki.org/wiki/Help:Extension:ParserFunctions ParserFunctions]: #if et al.
DNA samples taken from modern Native Americans do not match the DNA of modern inhabitants of the Middle East. Critics argue that this means the Book of Mormon's claim that Native Americans are descended from Lehi must be false, and therefore the Book of Mormon is not an ancient record as Joseph Smith claimed.

==Response==
 
 
 
Few criticisms of the Church have received as much media attention as this criticism, with so little thought and science being applied to the question.  DNA attacks against the Book of Mormon account fail on numerous grounds.
 
 
 
===Initial considerations===

===A Question of Geographies===
 
 
 
It is important, as when setting out to answer any scientific question, to define the question which DNA-based attacks are attempting to answer.  This requires that we establish a Book of Mormon model for potential testing.  Any Book of Mormon model based in real history must address the issue of geographic scope.
 
 
 
The Book of Mormon account has been understood by the LDS in at least two broad [[Book of Mormon geography|geographical contexts]]:
 
# a hemispheric model (Click [[Book_of_Mormon_geography:New_World:HGT|here]] to read more about such models.)
 
# a limited geographic model (Click [[Book_of_Mormon_geography:New_World:LGT|here]] to read more about such models.)
 
 
 
Details on these models are available in the links above; it is assumed that the reader of this article is familiar with these concepts, and they will not be elaborated on here.
 
 
 
However, DNA attacks on the Book of Mormon are arguably futile, regardless of which geographical model one adopts.  Some geographic models pose problems for the DNA attacks which other models do not.  This article will therefore examine the DNA issue from a variety of angles, and provide links for further reading which address the various models.
 
 
 
====Limited geography models====
 
 
 
Many Book of Mormon readers, especially during the last sixty years, have read the Book of Mormon text as requiring a relatively small geographic area within the Americas.  Such readings predate issues of DNA and genetics by decades, and are not (as the critics sometimes claim) desperate "rear-guard" actions to defend the Book of Mormon against the awesome onslaught of DNA science!  Such claims are ridiculous, as a review of the history of such ideas shows.{{ref|roper1}}
 
 
 
LDS readers who accept a limited geography model would find it unsurprising (and even expected) that the majority of Amerindian DNA does not match purported "Lehite" DNA.  Under the limited geography model, a relatively small number of Lehites landed in the Americas.  This small initial population eventually intermarried with other populations in the hemisphere.  Over a period of 2600 years, any initial Lehite "signature" would be hopelessly 'swamped' by other peoples' genetic markers.  Just as a drop of red dye will not turn a whole swimming pool red (though the red is still "in" the swimming pool), a few Lehites added to a limited geography model's hemisphere of inhabitants will have little or no detectable genetic influence today, except by the greatest coincidence.
 
 
 
Critics such as Murphy and Southerton ignored this option completely, demonstrating their complete ignorance of much LDS thought on the matter in the past sixty years.  Many articles have discussed the DNA issue from this perspective, including the following:
 
 
 
* {{FR-15-2-6}} <!-- McClellan - Detecting-->
 
* {{FR-15-2-7}} <!--Roper - Nephi's neigh-->
 
* {{FR-15-2-8}} <!-- Roper - Swimming-->
 
* {{FR-16-2-5}} <!--Tvedtnes Reinventing-->
 
 
 
====Hemispheric geography model, type 1====
 
 
 
Other Latter-day Saints have understood the Book of Mormon on a more "hemispheric" scale, with the "narrow neck of land" being in Panama, and the final battle site being located in New York, in the hill in which Joseph Smith recovered the plates.
 
 
 
Thus, this model anticipates that Book of Mormon history played out over much of the continent.  However, it is here labeled as a "type 1" model, because it does not require that Lehi be the sole "source" of population for the Americas.  Jaredite remnants may have intermarried with Lehite/Mulekite peoples, contributing foreign DNA markers.  Other peoples unmentioned in the Book of Mormon may have immigrated to the hemisphere before, during, and/or after the Book of Mormon time frame, and provided DNA foreign to Lehi's group.  These additions could have played a major, even dominant role in the genetic history of the continent (in which case the DNA attacks can be answered in a fashion similar to the 'limited geography model' as above) or they may have provided a more modest contribution which is nevertheless sufficient to "muddy the waters" when the other uncertainties of assigning DNA origins to mixed populations come into play.
 
 
 
Articles which discuss LDS views on "other Americans" being added to the mix of Book of Mormon peoples (which do not require a limited geography model to maintain their force) include:
 
 
 
* {{FR-18-1-6}} <!-- Butler - Addressing-->
 
* {{FR-15-2-7}} <<!--Roper - Nephi's neigh-->
 
* {{FR-15-2-8}} <!-- Roper - Swimming-->
 
 
 
Articles which do not invoke any type of "limited geography" in their discussion include:
 
 
 
* {{FR-18-1-7}} <!--Stewart -- DNA and the Book of Mormon--> {{NB}}
 
 
 
====Hemispheric geography model, type 2====
 
 
 
This model might be best described as an "empty continent, Lehite-only" model.  Under this model, the American continent was completely empty of any human inhabitants prior to the Jaredites (though previous to the Jaredites, other peoples could have been present who were subsequently eradicated, leaving no genetic contribution to subsequent populations.)  The Jaredites were then utterly and completely destroyed (except Coriantumr&mdash;see {{s||Omni|1|21}}, whose contribution was either negligible or non-existent to the Mulekite gene pool) and replaced by Lehite/Mulekite immigrants, who were likewise the ''only'' source of humans in the Americas, giving rise to all (or nearly all) of the present Amerindian population.
 
 
 
Of all the models discussed thus far, this is the only variant to which the DNA data poses any significant challenge at all, though many of the issues discussed below also apply to DNA testing the Book of Mormon's claims with this model.
 
 
 
Articles which do not invoke any type of "limited geography" in their discussion include:
 
 
 
* {{FR-18-1-7}} <!--Stewart -- DNA and the Book of Mormon--> {{NB}}
 
 
 
====Hemispheric geography model, type 3====
 
 
 
Under this model, the Americas has had no inhabitants ''except'' those mentioned in the Book of Mormon.  Thus, Jaredites, Mulekites, and Lehites are the only inhabitants the New World has seen before Columbus. 
 
 
 
A larger problem for this model than DNA evidence is archaeological evidence of human habitation thousands of years prior to the Nephites (which would have to be explained by either appealing to dating errors, or ascribing all such remains to Jaredites).  This model is arguably the most challenged by current DNA science&mdash;and science in general&mdash;but it is also the least likely model supported by the Book of Mormon text itself.
 
 
 
==General genetics issues==
 
 
 
Regardless of the geographical model used, efforts to date at "testing" the Book of Mormon through the use of genetic data encounter a number of problems and issues that should be considered.
 
 
 
===Are all Amerindians descendants of Lehi?===
 
 
 
Newspaper accounts have sometimes dramatically recounted how Church members from various Amerindian groups (e.g. Navajo, Pacific Islanders) have expressed dismay at the idea that DNA has "proved" that they are not "really" descendants of Lehi as the Church has taught them.  Critics have also insisted that LDS prophets who have mentioned such ideas are "wrong."
 
 
 
Regardless of the population model which one uses, or the geographical model, this claim is demonstrably false. 
 
 
 
The popularity of Dan Brown's novel, ''The Da Vinci Code'', led many Christians to consider the question of whether (as the novel postulates) Jesus Christ could have sired children and have living descendants today.
 
 
 
Non LDS-writer Steve Olson (an expert in population genetics{{ref|olson1}}) wrote:
 
 
 
:If anyone living today is descended from Jesus, so are most of us on the planet.  That absurd-sounding statement is an inevitable consequence of the strange and marvelous workings of human ancestry...Say you go back 120 generations, to about the year 1000 B.C. According to the results presented in our Nature paper, your ancestors then included everyone in the world who has descendants living today... If Jesus had children (a big if, of course) and if those children had children so that Jesus' lineage survived, then Jesus is today the ancestor of almost everyone living on Earth. True, Jesus lived two rather than three millenniums ago, but a person's descendants spread quickly from well-connected parts of the world like the Middle East...In addition to Jesus...we're also all descended from Julius Caesar, from Nefertiti, from Confucius...and from any other historical figure who left behind lines of descendants and lived earlier than a few thousand years ago. ''Genetic tests can't prove this, partly because current tests look at just a small fraction of our DNA.'' But if we're descended from someone, we have at least a chance—even if it's a very small chance—of having their DNA in our cells...People may like to think that they're descended from some ancient group while other people are not. But human ancestry doesn't work that way, since we all share the same ancestors just a few millenniums ago.{{ref|olson2}}
 
 
 
If Lehi existed, and if he left ''any'' descendants who survive to the modern day, then it is overwhelmingly likely&mdash;via the laws of population genetics&mdash;that virtually ''all'' modern Amerindians count Lehi among their direct ancestors.  (If someone in the Middle East at the time of Christ would be the ancestor of everyone currently alive, then Lehi's entry to the Americas 600 years prior to ''that'' time almost assures that he would be the direct ancestor of all Amerindians.)  In a similar fashion, it is even more certain that all Amerindians are descendants of "the Lamanites," regardless of whether one considers Lehi's group to have been "the whole show" genetically ''or'' a mere drop in a genetic sea.
 
 
 
And, by the same token, the chance of actually having "Lehi's DNA" or a DNA marker from Lehi is vanishingly small under most population models, unless (as in hemisphere model, type 3) Lehi is literally the ''only'' source of DNA for the continent, and even then not all descendants will have a given marker.
 
 
 
Another non-LDS author discussed the difficulties associated with using genetic tests to determine ancestory even a few generations back:
 
 
 
:Many amateur genealogists are interested in whether they might have a Cherokee ancestor, for example. And for some people, admixture tests can give a relatively accurate answer about Native-American ancestry. But other people, including Greeks and Ashkenazi Jews, may have "Native American affinity," according to the tests, even if they and their ancestors have never been to America. As far as anthropologists know, there were no lost tribes connecting Greeks, Jews, and ancient Americans. [LDS readers might pause here and wonder!] So, maybe this "Native American affinity" reflects the scattering of alleles by prehistoric Asian nomads to the ancestors of Greeks and Jews as well as to American Indians.{{ref|howafrican1}}
 
 
 
Articles which address the phenomenon of how large groups (or the entire human population) can have fairly recent common ancestors include:
 
 
 
* {{FR-18-1-6}} <!-- Butler - Addressing-->
 
* {{FR-15-2-8}} <!-- Roper - Swimming-->
 
* {{FR-15-2-9}} <!--Stubbs - Elusive Israel-->
 
 
 
===What are we looking for?===
 
 
 
Genetic attacks on the Book of Mormon focus on the fact that Amerindian DNA seems closest to Asian DNA, and not DNA from "the Middle East" or "Jewish" DNA.  However, this attack ignores several key points.
 
 
 
Lehi and his family are clearly ''not'' Jews.  They belong to the tribe of Manasseh ({{s||Alma|10|3}}, {{s|1|Nephi|5|14}}), and married into Ishmael's family, the tribe of Ephraim.{{ref|ephraim1}}  These tribes were carried away captive by the Assyrians, and did not contribute greatly to the current genetic mix of the Middle East.
 
 
 
Furthermore, the Middle East is located at the crossroads of three continents, and has seen a great deal of immigration, mixing, and intermarriage.  To use modern Middle Eastern DNA as the "standard" against which to measure what Manasseh and Ephraim DNA must have been like 2600 years ago is extraordinarily sloppy science.
 
 
 
Articles which consider that "Asian" DNA and Lehite DNA may actually correspond due to an earlier common source:
 
* {{FR-18-1-7}} <!--Stewart -- DNA and the Book of Mormon-->
 
 
 
===What Jewish DNA?===
 
 
 
Identifying DNA criteria for Manasseh and Ephraim may always be beyond our reach.  But, even identifying markers for ''Jews''&mdash;a group that has remained relatively cohesive and refrained from intermarriage with others more than most groups&mdash;is an extraordinarily difficult undertaking.
 
 
 
One author cautioned:
 
 
 
:Studies of human genetic diversity have barely begun. Yet the fashion for genetic ancestry testing is booming. . . . Other groups, such as Jews, are now being targeted. This despite the fact that Jewish communities have little in common on their mitochondrial side—the maternal line down which Judaism is traditionally inherited. It's the male side that shows common ancestry between different Jewish communities—so, of course, that's what the geneticists focus on. . . . Geneticists—like preachers and philosophers before them—need to avoid promising more than they can deliver.{{ref|genie1}}
