Speciation is not evolution - period, paragraph, end of story. Evolution requires new genes, new functions, new abilities, increased complexity. Splitting a species into two only separates the original gene pool of the species, it does not create new genes. In addition, at least one of the two species, if not both will be less viable than the 'wild type' which had the complete gene pool. This is the result of all breeding experiments where a new 'breed' is developed.
The examples cited in that webpage show in increase in the chromosone count. Are you suggesting that this is all junk DNA?
