That's interesting, because I don't really think of a "culture" as smaller than a "civilization". I think of a culture being a necessary thread that runs through a civilization and without which there are no civilizations.
Traveling overland across Africa will swiftly disabuse you of the notion that hunter/gatherer lifestyles make up any "large portion" of the continent's population. It would hardly even be feasible in the face of massive deforestation and population boom.
Africa comprises an entire continent. There are not large portions of it (or "large swaths") where people still live as hunter-gatherers living in mud huts, for any reasonable definition of "large portion."
… Eh? Even by the most generous possible definitions (including people who are primarily hunter gatherer but interact with the local economy to some extent), there are only on the order of tens of thousands of hunter gatherers today, worldwide.
As for mud huts, still commonly used in some places; there’s nothing particularly wrong with mud/earth construction if it works in your local climate.
Uh, what? I'm not sure where you are pulling that accusation from. I said very succinctly that I was not talking about what was the majority in Africa. I think you are confused.
