Humanity originated in Africa, and as soon as human societies existed they began to engage in economic activities. The earliest humans were hunter-gatherers who lived in small family groups.

Archaeologists have found evidence that the trade in luxury items such as precious metals and shells occurred throughout the entire continent.
