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.
Giraffomorpha is a clade of pecoran ruminants containing the superfamilies Palaeomerycoidea (Palaeomerycidae) and Giraffoidea (Giraffidae, Prolibytheriidae and Climacoceratidae), of which the giraffe and okapi of the Giraffidae are the only extant members of the once-diverse clade as a result of a decline in diversity after the Miocene as a result of declines in temperatures.
