The Mysteries of DNA

I have six siblings. Most of the time, due to living great distances apart, and seeing each other rarely enough that we're on polite behavior, we get along just fine. Sometimes we disagree on things; sometimes it's politics, sometimes it's religion, health & diet, culture, art, etc., but we generally manage a healthy debate or have a few yucks making our points, calling each other idiots in a good-natured way, and moving on. "Well, I disagree with you there, I think the problems with X and Y are more to do with Z or what have you. I'm not sure how you arrived at this conclusion, knowing this, that, and the other, but I think you might be insane if you continue in this line of thought after having read such and such book, or seen this documentary or that news article. And I don't know how you can listen to that (insert musical artist of your choice here) crap, it makes my ears bleed. But...anyway, anyone want another beer? Sure! How about them Red Sox."

But I have one brother who...well, I don't know what to say except that I do not know HOW the DNA that produced me could possibly have produced him. I think he's a changling. I want to know what my mother was eating and drinking ...and smoking... during THAT pregnancy, because... something's missing from the helix on that one.

There. I said it.

That is all.
