The idea that early human society was matriarchal comes out of wild speculation by certain authors with a political bent.
No offense, but I'd rather trust that guy's story than some random dude on the internet's.
https://en.wikipedia.org/wiki/List_of_matrilineal_or_matrilo...
The Akans of Ghana, West Africa, are matrlineals. Akans are the largest ethnic group in Ghana. They are made of the Akims, Asantes, Fantis, Akuapims, Kwahus, Denkyiras, Brongs, Akwamus, Krachis etc.
"Matrilineal" means property is passed down through the maternal line on the death of the mother, not that of the father.
There are a substantial number of matrilineal societies, probably due to the ease of knowing who your mother is compared to your father, before genetic testing was developed. They are quite often not matriarchal, though.
Also weren't most very early societies without marriage matriarchal?
Addition: Isn't this also ignoring polygamist marriage?
