In Circular RNAs Increase Cell Bio-Complexity (5 April 2013) Jeffrey Tomkins makes the arguement we’ve seen so many times even in the last week: something has been found to be biologically functional, therefore “bio-complexity” has increased, therefore design, therefore God.
The specifics are thus not hugely important. DNA can code for a variety of “RNAs” as well as just proteins – the function of these “circular RNAs” is apparently to act as a sponge for another RNA type, microRNAs. It doesn’t strike me as something that would be all that difficult to evolve, I have to say. Here’s a slightly more detailed summary, if you’re still interested.
Tomkins concludes his article by saying:
One prominent molecular biologist, Erik Sontheimer, proclaimed in an interview with Nature editors over the discovery, “You just wonder when these surprises are going to stop.” The answer is, they probably won’t—because scientists have only begun to scratch the surface in discovering the complexity of the cell which has been engineered by an omnipotent and all-powerful Creator.
The alternative explanation is that the surprises will never stop because biology has had billions of years to come up with anything and everything possible, but you already knew that. Tomkins, meanwhile, really needs to come up with something new.
