Karoo dwarf chameleon no means closely related. Rather, the Karoo dwarf chameleon belongs to a group of mostly short-tailed drab "Bradypodion" species which mostly inhabit semiarid to arid habitats. Its closest living relatives among these appear to be the peculiar and nearly extinct Smith's dwarf chameleon from mountainous habitat, and especially the southern dwarf chameleon. The Karoo dwarf chameleon may actually be a subspecies of the latter; there appears to be significant gene flow between the two.

Karoo plain with Mississippi-like rivers depositing mud from an immense range of mountains to the south. Ancient reptiles and amphibians prospered in the wet forests, and their remains have made the Karoo famous amongst palaeontologists. The first of these Karoo fossils was discovered in 1838 by Scots-born Andrew Geddes Bain at a road cutting near Fort Beaufort. He sent his specimens to the British Museum, where fellow Scotsman Robert Broom recognised the Karoo fossils' mammal-like characteristics in 1897.
