On the similarities of cultures or on those things that make the cultures unique?

Please answer the following question. Your answer should be thorough and demonstrate your understanding of the material.

An Afrocentric perspective of this topic argues a position that Africa during the period discussed was the history not of diverse people with diverse culture, but a single cultural unit based around the Nile Valley civilization. The argument advocates that to focus on the difference of the Kingdoms is a mistake and that the focus should be on the similarities which define the continent. The opposite argument says to place emphasis on the similarities without acknowledging the creativity and adaptive behavior is a mistake. Take a position. Where should the emphasis be? On the similarities of cultures or on those things that make the cultures unique?

Make sure you support your answer with evidence from the readings.
