No, it definitely not the same. Arabs are definitely a diversity of different people, and i am not speaking about the one in African but in the Arabian peninsula.
You have this in the Arabian peninsula
You see many of these types in the Arabian peninsula from Saudi Arabia to Oman, at the same time there is a great deal of diversity of types from fair skin to dark in those countries.
This is what i reckon you find in the states often, which i can understand, because they are numerous in the Arab world as well.
Like Africans vary so do other groups vary.
