Human arrival in Ivory Coast has been dated to the Upper Paleolithic period, or at the minimum, the Neolithic period based on weapon and tool fragments, specifically polished shale axes and remnants of cooking and fishing. The earliest known inhabitants of Côte d'Ivoire left traces scattered throughout the territory. Historians believe these people were all either displaced or absorbed by the ancestors of the present inhabitants. Peoples who arrived before the 16th century include the Ehotilé (Aboisso), Kotrowou (Fresco), Zéhiri, Ega, and Diès (Divo).
