Do I understand you right? You mean that Ghassulian culture represents the
Proto-Semites, the ancestor of _all_ known Semitic tribes? In other words,
these tribes were so successful in the Bronze Age due to the Mediterranean
form of agriculture (particularly, using olive for oil and grape wine as the
main alcoholic drinks)?
