 Although the two proponents of the Black Egyptian Hypothesis presented what G. Mokhtar referred to as "extensive" and "painstakingly researched" evidence to support their views, which contrasted sharply with prevailing views on Ancient Egyptian society, nearly all participants concluded that the ancient Egyptian population was indigenous to the Nile Valley, and was made up of people from north and south of the Sahara who were differentiated by their color.Diop and others believed the prevailing views were fueled by scientific racism and based on poor scholarship.Since the second half of the 20th century, most scholars have held that applying modern notions of race to ancient Egypt is anachronistic.
