Professor of African Studies at Rutgers University, Dr. Van Sertima was also Visiting Professor at Princeton University. He is the Editor of the Journal of African Civilizations, which he founded in 1979 and has published several major anthologies which have influenced the development of multicultural curriculum in the United States. These anthologies include Blacks in Science: ancient and modern , Black Women in Antiquity , Egypt Revisited , Egypt: Child of Africa , Nile Valley Civilizations (now included within the pages of Egypt: Child of Africa), African Presence in the Art of the Americas, African Presence in Early Asia (co-edited with Runoko Rashidi) , African Presence in Early Europe , African Presence in Early America , Great African Thinkers , Great Black Leaders: ancient and modern and Golden Age of the Moor .
Other researchers have argued that the Olmec civilization came into existence with the help of Chinese refugees, particularly at the end of the Shang dynasty .  In 1975, Betty Meggers of the Smithsonian Institution argued that the Olmec civilization originated due to Shang Chinese influences around 1200 BCE.  In a 1996 book, Mike Xu, with the aid of Chen Hanping, claimed that celts from La Venta bear Chinese characters.   These claims are unsupported by mainstream Mesoamerican researchers.

The Swiss archaeologist Charles Bonnet's discoveries at the site of Kerma shed some light on the theories of Diop. They show close cultural links between Nubia and Ancient Egypt, though the relationship had been acknowledged for years.  This does not necessarily imply a genetic relationship, however. Mainstream Egyptologists such as F. Yurco note that among peoples outside Egypt, the Nubians were closest ethnically to the Egyptians, shared the same culture in the predynastic period, and used the same pharaonoic political structure.  He suggests that the peoples of the Nile Valley were one regionalized population, sharing a number of genetic and cultural traits.
