Strictly speaking there is no distinction between Jordanians and other Levantine groups.
The “Arabs” in the region from the Sinai to the borders with Turkey and Iran are a mix of Canaanites, converted Israelites, assyrians, sumerians, amorites etc.
The Palestinians do have some Jewish ancestry,
Arabs and Jews, as I understand it are called “Semitic’’ peoples. Again there is no racial group known as Palestinians. It’s a lie Arabs have used for decades to attack Israel.
