Editing Proto-Semitic language (section)

=== Levant hypothesis ===
A [[Bayesian inference|Bayesian analysis]] performed in 2009 suggests an origin for all known Semitic languages in the Levant around 3750 BC, with a later single introduction from [[South Arabia]] into the [[Horn of Africa]] around 800 BC. This statistical analysis could not, however, estimate when or where the ancestor of all Semitic languages diverged from Afroasiatic.<ref name="Kitchen2009">{{cite journal|last1=Kitchen|first1=A.|last2=Ehret|first2=C.|last3=Assefa|first3=S.|last4=Mulligan|first4=C.

In another variant of the theory, the earliest wave of Semitic speakers entered the [[Fertile Crescent]] via the [[Levant]] and eventually founded the [[Akkadian Empire]]. Their relatives, the [[Amorites]], followed them and settled Syria before 2500 BC.<ref name="Lipinski44">{{Harvnb|Lipiński|2001|pp=44}}</ref> [[Late Bronze Age collapse]] in [[Israel]] led the [[South Semitic languages|South Semites]] to move southwards where they settled the highlands of [[Yemen]] after the 20th century BC until those crossed [[Bab-el-Mandeb]] to the [[Horn of Africa]] between 1500 and 500 BC.<ref name="Lipinski44" />
