>>>“This fascinating and unanticipated new property of DNA has the potential to cause substantial damage to our cells, leading to cancer or other diseases, unless it is controlled or exploited for some beneficial purpose,” she said. “We will stay tuned.”<<<

Looks like the Law of Entropy strikes again, and the biggest objection (apart from irrationality of matter being eternal) to genetic evolution stays. There are NO good mutations.

Every mutation has an opposite mutation. So if bad mutations exist then so do good mutations, in equal quantity.

What, exactly, does the "Law of Entropy" state?

There are NO good mutations

I am afraid that your claim is demonstratably false.

"There are NO good mutations."

If you are trying to say that every mutation is deleterious you are simply incorrect. Though the majority of mutations are deleterious (lethal mutations are fairly rare)to the fitness of the organism, neutral mutations also make up a large percentage of total mutations. Adaptive mutations, though rare, do in fact occur at a fairly high rate when given the population sizes (billions/trillions of organisms) usually discussed in the natural world.
