The different subspecies are close enough that most scientists do not think they should be classed as different species. Because one person thinks they should be different species is not enough to make it a new species, the scientific community at large must be convinced of it, that has not happened yet. Regardless, it is not an example of macro evolution. They do not show sufficient new complexity, new features and new (not altered genes) to qualify as proof of macro-evolution.
