Theory of origin states that DNA can lead researchers to a specific date that the first of a species originally occured. Natural selection deals with the process by which random generation of attributes help one animal to survive and not another, thereby selecting on of the two to procreate. The two theories are not really related in a way that you can contrast them, as they deal with separate subjects, not arguing ones.

Well if I can't say both(which I really am), I'll go with mysterious. I'm more of that than I am mischievous, even though I pretend to be otherwise ;)

d.  The way to tell when you have a compound noun is to remove the other noun E.g.  A)Please give I your undivided attention.  That makes no sense.  Only d does.

Actually (this is going to sound stupid) I have both, so I'm compulsive I just keep randomly noticing things that irk my compulsions-- so funny, they seem so contradictory, but alas, no

Excellent point, buddy.  It is often subtle and subliminal (word stucture and sentences).  Good job bringing this to the forefront.

I think you can be both! You can be sound while having a valid point; by the same token, to be sound, there has to be at least some validity to it...

People say they are spirits. Or energy of them. But you have to be careful cause sometimes they get mixed up with dust. There is a difference. take a picture of some dust and compared the two. Also sometimes it can be the lighting in the photograph.

I suggest learning english first.  Studies show that you think in the language you speak.  And obviously your language is degraded.  Try an upgrade.

His left is your right isn't it? Perhaps you are righthanded and therefor your right eye dominates and stares at it's choice, the closer object to it (being the left eye of the other person). Try looking at a lefthanded or leftbrain dominant person and see if there's a difference. ^__^

It's kida hard to explain comprehensively in 1000 characters or less, so the next best thing I can do right now is put a link to a website that explains the  diferences in layman's term in the source below.\nHope that helps you out.
