@DNA Thumbs drive,
												Your analogy is faulty. Darwins theory was about HERITABILITY OF TRAITS that VARY INCREMENTALLY through TIME , and that was all about ability of the life forms to successfully adapt through evolution.
His theory was about many things we see today but his idea and work still is considered one of (or maybe THE) best ideas of the millennium.
Understanding genetics and its  chemical mechanisms has not invalidated anything of Darwin's discovery. In fact, the only blunder he made  in his "Origins..."was to posit that  the heritable traits responsible for evolution were actually "diluted" by successive generations. (That was more a correction that was made by understanding the persistance of individual  genes revealed  from   Mendelian genetics and not from  genomics)
DNA is merely the "bookkeeping mechanism" of evolution.  We see microevolutional changes occur in species for  generations with 
measurable morphological changes , all WITHOUT any DNA modifications.
PS, if your passion is about the creation of life, you've been in error to consider thi  biochemistry as prt of evolution theory (Theres actually NO PLACE FOR IT).
