Centered on the city of Akkad, the Akkadian Empire, which existed in the third millennium B.C., was the first Semitic-speaking empire of the Tigris-Euphrates Valley.
The Akkadians believed in omens, that is, in the idea that present-day occurrences can foretell future events. For this reason, they compiled lists indicating the expected future consequence for each different kind of event. Among those omens were cases in which animals were observed choosing mates not of their own kind. Their listings of such cases are interesting not only because they show that the Akkadians knew animals do in fact make such choices, but also because they provide information about the specific combinations of which the Akkadians were aware. Many of these combinations have been forgotten in modern, urban-oriented culture.
The following is a collection of omens and consequences taken from Sally M. Freedman's interesting book If A City Is Set On A Height: The Akkadian Omen Series Šumma Alu ina Mele Šakin (vol. 3, The University of Pennsylvania Museum, 2017). These omens are quoted from ancient clay tablets, which are often broken or for other reasons illegible. So bracketed words and letters indicate portions of the omen text completed on the basis of other existing texts. Ellipses indicate missing text that could not be surmised.

In addition, Freedman (2017, p. 33) states that one tablet "preserves three wild animal omens in a context of sexual activity among different kinds of animals," which indicates that the Akkadians, who lived more than 4,000 years ago, were aware that hybridization occurs in the wild—something many people are no longer aware of today.
