The coat patterns of modern giraffes may also have coincided with these habitat changes. Asian giraffes are hypothesised to have had more okapi-like colourations. [6] The giraffe genome is around 2.9 billion base pairs in length, compared to the 3.3 billion base pairs of the okapi. Of the proteins in giraffe and okapi genes, 19.4% are identical.
The current IUCN taxonomic scheme lists one species of giraffe with the name G. camelopardalis and nine subspecies. [1] [7] A 2021 whole genome sequencing study suggests the northern giraffe as a separate species, and postulates the existence of three distinct subspecies, [8] and more recently, one extinct subspecies. [9] [10] [11]
Living giraffes were originally classified as one species by Carl Linnaeus in 1758, under the binomial name Cervus camelopardalis. Morten Thrane Brünnich classified the genus Giraffa in 1772. [ 6 ] Once considered a subspecies of the conglomerate Giraffa camelopardalis species, recent studies proposed the southern giraffe as a separate species ...
The South African giraffe or Cape giraffe (Giraffa giraffa [2] or Giraffa camelopardalis giraffa) is a species or subspecies of giraffe found in South Africa, Namibia, Botswana, Zimbabwe, Eswatini and Mozambique. It has rounded or blotched spots, some with star-like extensions on a light tan background, running down to the hooves.

The third ossicone can often be seen in the center of the giraffe's forehead, and the other two are behind each ear. Regarding the hybridization and habitat of the species: Rothschild’s giraffes have different genetic markers that other species usually do not, which keeps their populations safe from extinction and hybridization overlap.
