Where did the peoples of present day Ghana come from?

Question

Very often when I ask people this question, they start off with the arrival of the Europeans in West Africa or thereabouts.

But I am interested in the period before the arrival of the Europeans.

Answer 1

Per Wikipedia:

Ghana's population is concentrated along the coast and in the principal cities of Accra and Kumasi. Most Ghanaians descended from migrating tribes that probably came down the Volta River valley at the beginning of the 13th century. Ethnically, Ghana is divided into small groups speaking more than 50 languages and dialects. Among the more important linguistic groups are the Akans, which include the Fantis along the coast and the Ashantis in the forest region north of the coast; the Guans, on the plains of the Volta River; the Ga- and Ewe-speaking peoples of the south and southeast; and the Mossi-Dagomba-speaking tribes of the northern and upper regions.

Answer 2

The Mali and Asante were the peoples of Ghana. Although this is by western understanding it is presumed to be factual. The Mali were then the Asante took or gained Political control of what is now known as Ghana.
The Chinese were early to chart many parts of the African Continent, followed buy the Portuguese and other European interlopers.
