DNA ancestry.
Canaanites were a mix of Arab, Hamite, Turanid, Persian and S European. Well integrated! Mix was established before the Bible was concocted. Whether you were a Judean or a Philistine, same mix!
We don’t know who was first but we do know that the S Europeans were the last to arrive.
Today’s Palestinians, Lebanese, some Jordanians and Syrians share up to a 95% match to the same mix. That’s despite centuries of rule by foreigners. The people haven’t really changed! They are the descendants of Canaan.
The Judeans expelled by the Romans also have this mix – that’s the Djerba and Italian Rites Jews.
The mix has become known as Levantine – it’s unique!
