Europeans
(East) Asians
(Sub-Saharan) Africans
Phenotypically many Southern African populations have traits associated with East Asians like epicanthal/double eyelids and I wouldn't blame anyone for mistaking Saami or even some Finns as coming from somewhere in Asia.
What significantly seperates Southern Italians, Sicilians and Greeks from say North Africans and what significantly seperates Ethiopians like the jeweled woman pictured above from other Semitic people like Arabs and Berbers?
Btw, I feel like I put way too much work into this response...
