Since the onager is an Asian animal, it suggests that this region may have been the origin of the alternative fable recorded as 183 in the Perry Index. In this the wild ass at first congratulates a grazing pack-animal's sleek condition but eventually is grateful for his own freedom after seeing the other being driven along beneath a load. A later 'Christianised' version is now numbered as the independent fable 411 in the Perry Index. There the onager jeers at a donkey, only to be eaten by a
Onager ancestor of all modern equids (members of the genus "Equus") lived around 5.6 (3.9–7.8) million years ago (Mya). Direct paleogenomic sequencing of a 700,000-year-old middle Pleistocene horse metapodial bone from Canada implies a more recent 4.07 Mya for the most recent common ancestor within the range of 4.0 to 4.5 Mya. The oldest divergencies are the Asian hemiones (subgenus "E. (Asinus)", including the kulan, onager, and kiang), followed by the African zebras (subgenera "E. (Dolichohippus)", and "E. (Hippotigris)"). All other modern forms including the domesticated horse (and many fossil Pliocene and Pleistocene forms) belong to the subgenus "E. (Equus)" which
