There's a possibility that the Northern White Rhino animal is very different to the Southern White Rhino animal.
> Following the phylogenetic species concept, recent research has suggested the northern white rhinoceros may be an altogether different species, rather than a subspecies of white rhinoceros, in which case the correct scientific name for the former is Ceratotherium cottoni. Distinct morphological and genetic differences suggest the two proposed species have been separated for at least a million years.[18]
There are more important species in endangered status, in my opinion. Millions of dollars for a hopeless cause to save an animal that only has a small genetic difference and very little physical difference.
"The danger in making this sort of suggestion, however, is that changing the taxonomy to suit conservation priority could eventually backfire: it would not look good if zoologists were thought to be tweaking their conclusions in order to suit their favoured conservation projects."
