It used to be like that. The pure Arab is very minority and they are mostly dark like Somalis. In the past, people were Arabized only if they speak Arabic.
Some historians and anthroplogists have founded that Arabs are a mix of Kurdish and Black. Prophet Ismail's mother was a Black women and his father Ibraahim came from Mesopatamia, the ethnographic region of Kurdistan. Prophet Mohamed(PBUH) is a descendent of Prophet Ibraahim, so it it reasonable to say that our prophet himself was not an Arab, ethinically.[/quote]
There is an arab ethnicity but they are a minority in the entire arab population.
Ther population of the arabian peninsula is arab, through millenia of migration the arab tribes migrated to mesapotamia, but still at least half of the population are arabized semetic tribes, the same with syria.
Egypt recieved an even smaller migration of arab tribes and the vast majority are Egyptian not arab and the Greek and Roman blood is as signifigant in Egyptian society as arab blood.
libya recieved a large mgration of arab tribes but still a large part of the population is berber.
To the west of Libya arabic influence is even smaller geneticly, but they have still been arabized.
No the origin of arabs is not conclusive, there are 2 theories.
1. The only arabs originated in Yemen and that the Prophet Ibrahim's decendants were arabized as a result of growing up amongst the arabs from yemen that migrated into arabia.(ibrahim himself was from the plains of aram in northern syria, spoke arameac, people from aram and jews were indistinguishable and old hebrew and old aramiac were mutually intelligable).
2.That all semites are considered(arab) and are decendent from yemen and from 2 brothers Adnaan and Qaxtaan
the prophet muhamed is considered to be a dedenant of Adnaan.
