Still, assuming there are no global catastrophes that plunge us back into a pre-technological age, we're probably nearing the point where our control over ourselves at the genetic level will override any potential for further evolution. Anymore significant changes to the human form, if they occur, will probably be intentional and controlled.

Ah, oops, I should apologize for my defensiveness, then - I assumed (a bit too quickly, it turns out) that you were being critical of asking about things from fictional science, but since that's not the case, sorry about my reaction.

Not being a biologist, I obviously got the idea from science fiction, but I don't see what's so funny about trying to find out whether there's any truth to it. It's an interesting idea. I presume "spiral-shaped EM interference" is a reference to another fictional idea, but I have no idea how it relates to this otherwise.

Ah, thanks. So, if life had evolved around a triple helix, would it externally be much the same as double helix life? Or is there no way to tell what differences there might be?

Haha, I understood almost none of that. Any chance of a simplification? Is it saying that creatures can't be built entirely from triple helix DNA?

And what effects does it have?

I'm sure a ladder with 3 legs could work, it'd just be more complicated, or 2 people could climb it at once if it was leaning on something. Anyway, a Google for "triple helix DNA" yields plenty of results, but I don't really know enough about biology to understand any of it - so what are they all about?

Does it exist? Can it exist? Could it evolve naturally? Are there any inherent advantages to being a triple-helixed animal? How would a triple-helix lifeform differ from a double-helixer? What about multiple helixes? What effects would DNA of multiple helixes have on the creature that possessed it?
