The ancestors of the Palestinians include the Canaanites as well as the other people that lived in the area.
I marked your post "Funny" because it took until the 20th century for these
"descendants of Canaanites" to come forward, and ONLY when the indigenous wanted to recreate their ancient Nation.
Now, either these are amazingly "slow" descendants of the Canaanites, or....there must be another explanation as to why it would take them over 3000 years to come forward as being descendants of the Canaanites.
Now, why didn't they call themselves Canaanites in the first place pre and after the 20th Century and the recreation of the Nation/State of Israel?
Why bother to start calling themselves Palestinians in 1964, and not Canaanites?
And exactly WHICH Canaanite tribes are they?
The Jebusite, the Hittites, the Philistines....

They MUST have kept their identity and known which of those tribes they came from, just as the Copts, Assyrians, Kurds, etc still do.
So, where are the Hitites? The Edomites?
There are many texts and letters referring to Canaanite tribes 4,000 years ago. Why do none of these refer to the people as Palestinians, or any of those tribes?
Caananite tribes, NOT Palestinians.
The Israelites are referred to as such, and not as Palestinians, or Canaanites post King David
No Archeological of a People, nor Tribe calling themselves Palestinians.
No text or document referring to a People or a Tribe called Palestinians.
No text or documents of the Greeks, Romans, Byzantine, Muslims, Crusaders, Ottomans or the British meeting any Palestinian Nation or People.
Forcing Canaanite ancestry on those who have none, or very little because of conversion or mixed marriage, does not a People make, and it does not give them the rights to a land in which the indigenous Jewish Nation/People have continued to inhabit....ALWAYS, since Judaism came to be nearly 3800 years ago.
Keep digging very deep for those non existent Arab tribes in Canaan.
Not in Egypt, not in Phonecia, not in Persia, not in Syria, not, not, not......
I cannot find them anywhere
And neither can modern ways of figuring out where people originated from , like..... DNA
Not even the creation of Islam 1400 years ago, turned any of those Arabs (even if anyone of them married those Jews who were forced into Islam at any time) into Palestinians, as endless Muslim writings before WWI attest to.
