Thank you Jack, I was careless here. What I really was referring to is the darwinian evolutionary process….there is no such thing at the molecular level…a point I tried to reiterate at post #23, viz., that a change in the sequence of nucleotides on a DNA molecule offers a defective framework for studying evolution.


I'm not interested in wading in over there again, but what could "a change in the sequence of nucleotides on a DNA molecule offers a defective framework for studying evolution" possibly mean?
