As far as I'm concerned, the most serious "problems" with the Book of Mormon have nothing to do with DNA studies and population genetics. That said, I have been somewhat of a student of the scientific theories concerning the origins of the various populations of the Americas... they are finding that there is evidence of extensive contact between Europe and the Americas, all throughout ancient times. The old theory about the Bering Straits being the only avenue of emigration into the Americas is being shown as entirely inadequate to explain the evidence. The Raghavan study published in Nature in November of last year is just the most recent study to underscore the increasing amount of evidence that the DNA picture of ancient America is not nearly as simple as most of the non-Mormon/ex-Mormon arguments would have one believe.Ludd wrote:So argue against the Book of Mormon all you want. ... The picture emerging from the latest studies is one that seems to suggest lots of contact between the "Old World" and the "New World" going clear back to Roman times and earlier.
Where is the evidence for your last claim Mr somewhat of a student? There is currently no genetic evidence of significant pre-Columbian migrations from anywhere other than sub-arctic regions via eskimo migrations.
All the Raghavan study proved is that living Europeans share DNA markers with a 24,000-year-old Siberian. It is largely irrelevant because it predates the Book of Mormon and Israel (and Adam and Eve, and the Flood) by about 20,000 years. Populations in ALL major geographic regions share common sets and subsets of DNA markers. All living Eskimos share some DNA markers with Australian Aboriginals. Does that prove Eskimos came from Australia?
The "old Bering Strait theory" as you put it, is by far the best explanation for an abundance of facts. It is a well established truth that essentially all of the ancestors of the American Indians descend from Asian ancestors.
When Mormons are faced with uncomfortable scientific facts they are invariably told by their leaders that science is changing all the time so they shouldn’t be concerned. In the essay we are told the DNA data is “tentative”. But it is LDS beliefs about Native American ancestry that have been proven to be tentative. Once LDS apologists boldly aligned the Book of Mormon civilizations with the Olmec and Maya. The Lamanite presence has rapidly been contracting to the point that it has now vanished. In contrast to back-flipping prophets there has been a century long scientific consensus about where the ancestors of Native Americans came from and when they arrived in the New World. DNA is just helping to refine our knowledge.
