I have done some more research and have here the references in the book of Mormon proving that when groups of people often turned to wickedness. They were cursed with a dark skin. This is not to say all the descendants of those who were cursed are still evil, but because of their forefathers they still have the cursed skin....and in many cases, as with the Seed of Cain (dark Africans) they still have consequences of that curse today, as they have been unable to progress at the same rate as the rest of the world. Look at how Africa is a third world country, often in many countries unable to progress past the stone age, and how much of the non cursed peoples (The white countries) are first world...this is almost always the case...America, Canada, Europe, Australia..ect...
