@timmytom, your article is simply wrong. There are several types of gene mutations; they do not always occur by exchanging a single nucleotide for another, or several for several others, or swapping, etc. Sometimes a string of nucleotides is accidentally repeated. Sometimes information from one chromosome is accidentally inserted into another. Either of these mutations can result in a longer nucleotide chain than the original.
How does that make new genetic information?
