Equid hybrid

As early as the 3rd millennium BC, Mesopotamians crossbred the domestic donkey with the now-extinct Syrian wild ass to produce a hybrid known as a Kunga.

Horse-donkey hybrids (the mule and hinny) are also of ancient vintage, as evidenced by their presence in works such as the Iliad and the Hebrew Bible.

From the 20th century on, a greater diversity of equid hybrids have been created,[1] beginning with the crossbreeding of zebras and donkeys.

[2] Mules bred from mammoth studs and stock or draft mares can be as large as 17 hands and are as strong as a normal horse.

"hebra" "donkra" "zorse" "zonkey" Zebras are usually wild animals.
