Personally, I think this is a great change. There are far too many Latter-day Saints who seem to have assumed all Amerindians are descended from the Lamanites – and it isn’t a concept based in scripture. Of course, holding that opinion wouldn’t compromise your ability to worship, but I think it’s important for the "non-revealed" portions not to step on the toes of the revealed portions – for consistency’s sake, if nothing else.

In case someone is looking for more information on the Amerindian ancestor debate as it relates to the Book of Mormon, here are some good resources on FAIR Wiki:
