Anatomical evidence later led to a reclassification of the aardvark into its own Order, Tubulidentata, and molecular biology has confirmed this division, suggesting that the aardvarks represent the last remnants of an afrotherian clade that has been evolving independently since the late Cretaceous.
The order Tubulidentata first appears in the fossil record in the early Miocene of Kenya, and later members spread to Europe and southern Asia during the later Miocene and early Pliocene.
Due to scarcity of material neither the status nor the limits of distribution of the subspecies are known.
