Over at LDS Science Review, Jared* sees this new article as something of a breakthrough for evolutionists because it discusses some of the same principles and processes that are used to explain evolution. In fact, according the title of Jared's post, the new article means the Church is now teaching evolution.
Meanwhile, at Mormanity, Jeff Lindsay notes that "for some of us who love science and our faith, the new statement ... comes as a pleasant surprise." He believes the new Topic article is significant because it is scientifically oriented.
I think both of these bloggers are reading more into the article than it contains: It neither promotes science nor teaches evolution. Perhaps the following excerpt from the article has been overlooked:
"The conclusions of genetics, like those of any science, are tentative, and much work remains to be done to fully understand the origins of the native populations of the Americas. Nothing is known about the DNA of Book of Mormon peoples, and even if their genetic profile were known, there are sound scientific reasons that it might remain undetected. For these same reasons, arguments that some defenders of the Book of Mormon make based on DNA studies are also speculative. In short, DNA studies cannot be used decisively to either affirm or reject the historical authenticity of the Book of Mormon." (Topic article, paragraph 3.)
The article says to me that DNA questions about the Book of Mormon cannot be answered conclusively by science. And while some research appears to challenge the Book of Mormon, other research draws more favorable conclusions. The article appears to be an effort to balance the public record on this issue.
In a larger sense, the article says to me that the conclusions of science are tentative and whether one supports or opposes a particular theory, scientific arguments on both sides are speculative.
I like how Hugh Nibley said it: "The last word is a testimony of the gospel that comes only by direct revelation. Our Father in heaven speaks it, and if it were in perfect agreement with the science of today, it would surely be out of line with the science of tomorrow." (Maxwell Institute.)
