DNA repair mechanisms ‘shout’ creation
Tomas Lindahl, Paul Modrich, and Aziz Sancar won the 2015 Nobel Prize for Chemistry for discovering DNA repair mechanisms.1 As the BBC article says, “In the 1970s, scientists had thought that DNA was a stable molecule, but Prof. Lindahl demonstrated that it decays at a surprisingly fast rate.” This led him and then the others to look for repair mechanisms, and the researchers found several (hence the three recipients of the prize).
The article speaks of the repair mechanisms as “essential processes”. Indeed, without the repair mechanisms, DNA falls apart “at a surprisingly fast rate”. Once an organism dies, the repair mechanisms no longer operate and DNA decays. This means that fossils that are supposedly millions of years old should not have any intact DNA; but they often do, including dinosaur fossils.2
It should now be obvious to all that DNA could never have arisen by natural processes (i.e. just chemistry and physics) because even if that could happen, the DNA would be useless without the repair mechanisms to preserve it. Without the repair mechanisms, DNA would fall apart quicker than it could possibly come together (if it even could in the absence of the cellular machinery to put it together, which is itself coded on the DNA). Furthermore, no natural origin could possibly explain either the coded information storage system of the DNA or the highly ordered sequences of information on the DNA that specify how to make the protein components of life.
The repair mechanisms involve incredibly complex nano-machines3 that themselves defy the notion of naturalistic origins. The more we know about the science of life, the more it becomes clear that life came about by the action of an incredibly intelligent creator.4
