The fragility of DNA is the bane of Darwinism

DNA can only withstand so much mutation and breakage before it breaks down. An amazing system of repair enzymes keeps decay in check, mostly. Yet, without the crazy complex system of DNA maintenance and repair, life cannot exist, which brings up questions of how we got here.
