Lol, you guys know more about my religion then most! Just to specify though, it is true (as far as I can tell) that the native Americans are genetically from Russia, not Jerusalem. It is also true that popular Mormon belief believes them to be from Jerusalem, not Russia. Of course I'm going to dodge this little point with technical details...I'll let you decide whether technical details matter!
Popular belief has nothin to do with it though. Here is how you tell whether it is actually Mormon doctrine:
[list=a]
[*]You find it in the Book of Mormon
http://scriptures.lds.org/en/bm/contents
[*]You find it in the Doctrine and Covenants
http://scriptures.lds.org/en/dc/contents
[*]It is specified to be official (not personal) church beliefs by the quorum of the twelve or the president of the church
[/list=a]
I'll admit though, in this case, you happen to be correct. I'll even give you the reference for you. The book of Mormon does imply that the residents of the American continent that Europe meets after Columbus' expedition include the descendants of Lehi.
1 Nephi 13: http://scriptures.lds.org/en/1_ne/13 (hate to break it to you, but verses 4-7 probably doesn't refer to the Catholic church!).
If you read the prophesy, there is nothing to specify whether the Gentiles are European or Asian or anything else. So while science disproves popular Mormon theory, it really doesn't contradict the Book of Mormon (yeah, I know it comes darn close).
Just a little more about science too: the natives of North/South America are genetically three different cultures (one for the Aztec, one for the Incas, and at least one other), but I don't know which one except that some of them migrated from Russia.
