The Semitic family is a member of the larger Afro-Asiatic family, all the other five or more branches of which are based in Africa. Largely for this reason (on the basis of linguistic migration theory), Proto-Semitic is now widely believed to have first arrived in the Middle East from Africa around the 4th millennium BC<1><2>, although other linguists argue that, instead, Proto-Afro-Asiatic originated in the Middle East, and Semitic was the only branch to stay put<3>. In any event, once it appeared in the Middle East, Proto-Semitic spread outwards from its heartland in the Arabian Peninsula and the southern Levant. When written records begin in the mid 3rd millennium BC, the Semitic-speaking Akkadians and Amorites were entering Mesopotamia from the deserts to the west, and were probably already present in places such as Ebla in Syria.
