The acknowledgement of African diversity is important because historically Africans have been marginalized to a narrow "True Negro" extreme which was based on 19th Century racist pseudo-science. Recent studies have established that Africa has the most genetically diverse populations with the oldest ancestry, deriving from 14 ancestral African populations. These Ancestral populations migrated around Africa and eventually throughout the world. Africa has more than 2,000 distinct languages and ethnic groups, the largest phenotype variation,cranio-metric variation and dental variation in the world.

Both methods for estimating regional diversity show sub-Saharan Africa to have the highest levels of phenotypic variation, consistent with many genetic studies."

"The living peoples of the African continent are diverse in facial characteristics, stature, skin color, hair form, genetics, and other characteristics. No one set of characteristics is more African than another.(S. Keita, "The Diversity of Indigenous Africans," in Egypt in Africa, Theodore Clenko, Editor (1996), pp. 104-105. [10])
"Africa contains tremendous cultural, linguistic and genetic diversity, and has more than 2,000 distinct ethnic groups and languages.. Studies using mitochondrial (mt)DNA and nuclear DNA markers consistently indicate that Africa is the most genetically diverse region of the world." (Tishkoff SA, Williams SM., Genetic analysis of African populations: human evolution and complex disease. Nature Reviews Genetics. 2002 Aug (8):611-21.)
"..often research using 'true' stereotypes presents all tropical Africans with narrower noses and faces as being related to or descended from external, ultimately non-African peoples. However, narrow-faced, narrow-nosed populations have long been resident in Saharo-tropical Africa... and their origin need not be sought elsewhere. These traits are also indigenous. The variability in tropical Africa is expectedly naturally high. Given their longstanding presence, narrow noses and faces cannot be deemed `non-African.'(S.O.Y. Keita, "Studies and Comments on Ancient Egyptian Biological Relationships," History in Africa 20 (1993), page 134 )
