Modern-day populations from around the world carry particular blends of regional affiliations.
“We compared your DNA results to each of 60 geographic and ethnic populations and calculated which two of these populations were most similar to you in terms of the genetic markers you carry”
Egyptians are more Africans than Arabs, according to genographic.nationalgeographic.com, only 17% of Egyptians are Arabs, 4% Jewish Diaspora, 3% Eastern Africa, 68% North African, 3% Asia Minor and 3% Southern Europe.
According to the genographic, this reference population is based on native Egyptians. As ancient populations first migrated from Africa, they passed first through northeast Africa to southwest Asia. The Northern Africa and Arabian components in Egypt are representative of that ancient migratory route, as well as later migrations from the Fertile Crescent back into Africa with the spread of agriculture over the past 10,000 years, and migrations in the seventh century with the spread of Islam from the Arabian Peninsula.
The East African component likely reflects localized movement up the navigable Nile River, while the Southern Europe and Asia Minor components reflect the geographic and historical role of Egypt as a historical player in the economic and cultural growth across the Mediterranean region.
It also revealed that Lebanese are 14% Jews, 44% Arab, 11% North Africa, 10 Asia Minor, 5% Southern Europe and 2% Eastern Africa. This reference population is based on the native population of Lebanon. As some ancient populations migrated from Africa, they passed first through the Middle East en route to Eurasia.
Some populations stayed in the Middle East and over time developed unique genetic patterns. The mixture of Arabian, Northern Africa, and Asia Minor is unique to this part of the world. The Arabian and Northern Africa components reflect ancient patterns of settlement and interaction in the region, while the Silk Road may have served to add genetic patterns from farther north and east.
The Iranians are 54% Arabs according to the report, while 4% Eastern Africa, 2% Northern Africa, 4% Central Asia, 6% Asia Minor, 2% Southern Europe and 24% Southern Asia.
This reference population is based on native Iranians. As some ancient populations migrated from Africa, they passed first through south-western Asia en route to the rest of Eurasia. Some populations stayed in the Middle East and southwest Asia, over time developing unique genetic patterns. The large Arabian and Southern Asia components found in our reference Iranian population reflect these ancient patterns.
The Asia Minor and Central Asia components likely arrived via the migrations of groups originating in those regions farther north, such as the Turks and Mongols. The Silk Road also may have served to disperse Asian genetic patterns farther south and west.
According to the report, 81% of African-Americans are from West and Central Africa. The result also reveals that 3% are from Southern Europe, 9% Southern Africa, 2% Eastern Africa and 4% Great Britain.
The mixture of regions reflected is due to the centuries-long forced slavery from Africa to the Americas during the slave-trading era (Western and Central Africa, Southern Africa, and Eastern Africa). There is also a European contribution to the population (comprising the smaller Great Britain/Ireland and Southern Europe components).
