Well I was going to dig up the old dna disproves the Book of Mormon thread but we can put this here.
DNA proves the Book of Mormon.
Alma 63 About 56–52 B.C
5 And it came to pass that Hagoth, he being an exceedingly curious man, therefore he went forth and built him an exceedingly large ship, on the borders of the land Bountiful, by the land Desolation, and launched it forth into the west sea, by the narrow neck which led into the land northward.
6 And behold, there were many of the Nephites who did enter therein and did sail forth with much provisions, and also many women and children; and they took their course northward. And thus ended the thirty and seventh year.
7 And in the thirty and eighth year, this man built otherships. And the first ship did also return, and many more people did enter into it; and they also took much provisions, and set out again to the land northward.
8 And it came to pass that they were never heard of more. And we suppose that they were drowned in the depths of the sea. And it came to pass that one other ship also did sail forth; and whither she did go we know not.
Many LDS leaders have said that the Polynesian are descendants of Lehi, I could give some quotes but we will skip them.
My sweet daughter in law is from the Philippines and she recently had her dna check. It came back Asian, no surprise, some lower Asian as in India and Polynesian with some Tongan and Samoan. And surprise surprise 1% Native American.
My first thought was some poor lost Indian on Magellan's ship escaped or something but no this 1% goes back beyond the thousand year marker, I don't think they can tell much beyond that point dates. So there ya have it, American Natives living in the islands and traveling around all over the place just as the Book of Mormon says.
Isa 11
" And it shall come to pass in that day, that the Lord shall set his hand again the second time to recover the remnant of his people, which shall be left, ..... and from the islands of the sea."
