@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?

Genetic information is just nucleotide chains. Split the chains, tie them together in new ways, you've got new information.  If you started with just "ACGT", you could generate any arbitrary string by splitting, duplicating, and recombining elements.
