By that, do you mean the theory that life on Earth (human life included) derives from an intelligence, like the Flying Spaghetti Monster?
While a research group at Harvard would accept the 'intelligent' part, their transcription of books and such into chemical strands is in no way responsible for life. And that group also would insist that this is RECENT work, their reference lists don't include any publications from the dawn-of-life era.
And again, the chicken-and-egg problem arises, because the existence of that laboratory is evidence of life that pre-existed the novel use of DNA outside of replicating cells.
Face it, lots of circuits oscillate; it's just an easy thing to arrange (or fall into by accident).
Fractals are a purely mathematical way to make both cycles, and variations; we DO know that there are simple rules that give rise to such things.
Similarly, some chemical reactions cycle. The chemical reactions that we call 'life' just happen to cycle through the egg-embryo-fetus-kitten-cat phases rather than through phases measured in radians. Like DNA replication, there are cat images available on the Internet, for your further amusement.
