From various kinds of evidence it can now be argued that agriculture in Ethiopia and the Horn was quite ancient, originating as much as 7,000 or more years ago, and that its development owed nothing to South Arabian inspiration. Moreover, the inventions of grain cultivation in particular, both in Ethiopia and separately in the Near East, seem rooted in a single, still earlier subsistence invention of North-east Africa, the intensive utilization of wild grains, beginning probably by or before 13,000 b.c. The correlation of linguistic evidence with archaeology suggests that this food-collecting innovation may have been the work of early Afroasiatic-speaking communities and may have constituted the particular economic advantage which gave impetus to the first stages of Afroasiatic expansion into Ethiopia and the Horn, the Sahara and North Africa, and parts of the Near East.

19 A common presumption of scholars is that domestication of animals arose no earlier than the beginnings of plant domestication: consider the comments on the Tepe Asiab and Ganj-i-Dareh Tepe sites in Iran in Schmandt-Besserat, D., ‘The earliest precursor of writing’, Scientific American, ccxxxviii no. 6 (1978), p. 57Google Scholar. But livestock-raising certainly preceded cultivation in southern Africa and can be suggested to have preceded it in parts of the Middle Nile Basin; cf. Ehret, C., ‘Some thoughts on the early history of the Nile-Congo watershed’, Ufahamu, v, 2 (1974)Google Scholar, for a probable example in that region.

22 Hadramaut form, isolated in Asian Semitic and naming a plant native and almost endemic to Ethiopia, must be considered a loanword; medial /h/ arose as an attempt to render the glottalic release of Ethiopic *t', an element foreign to Arabic pronunciation.
