Do Africans share the same origin and culture?

The Culture of Africa is varied and manifold, consisting of a mixture of countries with various tribes that each have their unique characteristic from the continent of Africa. It is a product of the diverse populations that inhabit the continent of Africa and the African diaspora. Generally, Culture can be defined as a collective mass of distinctive qualities belonging to a certain group of people. These qualities include laws, morals, beliefs, knowledge, art, customs, and any other attributes belonging to a member of that society. Africa has numerous ethnic nationalities all with varying qualities such as language, dishes, greetings, and dances. However, all African peoples share a series of dominant cultural traits which distinguish African Culture from the rest of the world. For example, social values, religion, morals, political values, economics, and aesthetic values all contribute to African Culture. Expressions of culture are abundant within Africa, with large amounts of cultural diversity being found not only across different countries but also within single countries. Even though African cultures are widely diverse, they are also, when closely studied, seen to have many similarities; for example, the morals they uphold, their love and respect for their culture, as well as the strong respect they hold for the aged and the important, i.e. kings and chiefs.

No, Africa is a multicultural continent, with many diverse ethnic groups. While these ethnic groups don't share the same origin, many of these groups share similar cultural traits such as social values and religious values.  They also generally have high regard for their elderly and tribal leaders.
