It doesn't give a precise reference to the actual scientific paper that this is about, but my guess is that it's this in Physical Review Letters (access to subscribers only):
http://link.aps.org/abstract/PRL/v100/e258103
"Mutagenic Evidence for the Optimal Control of Evolutionary Dynamics"
Raj Chakrabarti, Herschel Rabitz, Stacey L. Springs, and George L. McLendon
Phys. Rev. Lett. 100, 258103 (2008)
I'll probably be able to get hold of it from work.

Here's a related paper by three of the same authors that's freely available:
http://arxiv.org/pdf/0806.2331v1
Optimal control of evolutionary dynamics
Raj Chakrabarti, Herschel Rabitz, and George L. McLendon
I have not read this yet.
I have, however, found plenty of biologists discounting the original journalistic article as manifesting ignorance of how evolution actually works, e.g. here:
http://scienceblogs.com/pharyngula/2008/11/prediction_selfpromoting_hype.php
So apologies if this was a false alarm of something interesting.

How nice. I had guessed something like this, including the idea that
control systems in the genome were passed along the generations (in
sexual organisms) by being contained in mitrochondrial DNA (from the ovum).
I also think there is strong evidence that evolution is actually E.
coli reorganization in the genome. Evolutionary changes are not
random saltations but smooth continuous changes, with occasional
changes in "direction." If evolution consisted of truly random jumps,
we wouldn's see gradual changes in characteristics. But gradual
change is the rule rather than the exception.
I'm attaching the World Futures paper. If you find out where to send
it, could you copy it to the authors?
Best,
