In the mid-twentieth century and corroborated ever since, researchers dredging the seafloor could not find any materials older than 180 million years.
<h3>
What do you understand by seafloor ?</h3>
The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan
Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.

Answer:
North Africa is diverse. It is a myth that all North Africans have the typical Mediterranean look. It is the people you mostly see on TV and in movies.
Many North Africans can only be classified as North African Blacks. You rarely see them on TV or in the movies. They mainly live in the southern regions or as isolated communities, even in the north or the center of North African countries.
Genetically, the e1b1b haplogroup is shared by people in North Africa, in the Sahara and in Africa south of the Sahara. The palest Kabyles, the darkest Somali, the blackest Maasai and the “yellowish” San further south in Southern Africa carry the e1b1b hg.
The Sahara desert does not divide Africa genetically or phenotypically.
The differences between North Africa and Africa south of the Sahara are related to history and culture.
The history of North Africa is intertwined inseparably with European history (Roman Empire, the Greek Empire etc.), Persian history, Arab history and the history of the Ottoman Empire.
North Africa belongs to the Mediterranean world, northern coastal regions particularly (the food is typically Mediterrenean food). North Africa belongs to the Arab World. Arab culture is very strong and dominant. There is also a major influence of the Turkish culture.
