Have you wondered why the buildings of ancient Egypt fell into ruins? Why did the modern Arab areas, which in the early Middle Ages were famous for developed science, universities, metamtics, simply civilization, suddenly come to a halt in development? How is it possible that the people who built the pyramids 5,000 years ago are now unable to guarantee drinkable water in the taps? Well, until the fall of Rome, North Africa was inhabited practically exclusively by white people, modern Europeans. Then came SUBSAHARIC IMMIGRATION, a mixing of genes that irreversibly changed the genetics of the inhabitants of these lands. A genetic study of North African populations has revealed a complex migration history, including a return flow of genes from more than 12,000 years ago and migrations from the Middle East, Europe and sub-Saharan Africa. Indigenous Maghreb heredity, more common in populations of historical Berber ethnicity, was discovered. Migrations from West Africa to Morocco and from the Nilotic population to Egypt have been dated to about 1,200 and 750 years ago.
