I don't have any issue with evolution per se. In the Pearl of Great Price, God tells Abraham that:
So why couldn't neandrathals and other potential forefathers simply be the intelligences that were simply less intelligent than Homo Sapiens?18 ...if there be two spirits, and one shall be more intelligent than the other, yet these two spirits, notwithstanding one is more intelligent than the other, have no beginning; they existed before, they shall have no end, they shall exist after, for they are gnolaum, or eternal.
19 And the Lord said unto me: These two facts do exist, that there are two spirits, one being more intelligent than the other; there shall be another more intelligent than they; I am the Lord thy God, I am more intelligent than they all.
I know that we like to think that there is a huge gap between apes and man and that God wouldn't have to pick a cutoff as the cutoff would be obvious, but maybe with an infinity of intelligences there is going to have to be a hard cutoff from "Adam" (potential to be like God) and "pre-adamites" (no potential to be like God).
Just some food for thought.
