Linda, I had to laugh when I saw your post, I pondered the same thing. We're all human, all basically the same, but few people want to recognize this. We do however, grow up in different cultures, each have different parents, so this makes us wonderfully, and uniquely different. If it wasn't for this it would make for a boring world. I think social sites like Facebook might be the medium to finally bring world piece. We all get along just fine, we just don't need politicians running things
Though, there was at least three distinctly separate species of ancient humans. I have a sneaking feeling there is more than just evolution going on, and I am not thinking from a religious point of view.
