This hut is clearly more elaborate than the huts we've seen from Pygmy, Bushmen and Hadza sources:
Traditional Zulu Hut
This "beehive" hut is from a completely different part of the world, and made of stone rather than wood and grass or leaves:
Stone "Beehive" Hut-- Bronze Age Ireland
It's beehive shape might well be a coincidence. Or it might have evolved from an earlier type much closer to the traditional African design:
"Celtic" Hut (reconstruction) -- Wales
I'm wondering how the stone hut was constructed. If a wooden framework, similar to the framework of the traditional African huts, were constructed first, it would have been easy to position the stones against the wood, which could be easily removed once the stone structure was complete. In this way it might be possible to imagine a single line of evolution from the wood and grass hut pictured above to the stone one. On the other hand, if some other method of placing the stones had been used, then the connection wouldn't be so clear.
The same thinking could be applied to these mud huts, from the Near East:
"Beehive" Mud Huts -- Harran, Turkey
[Added 11-22, 5:15 PM:
On the other hand, not all Igloos are made of ice. This one appears to be covered with skins and probably had a wooden frame:
Did the ice Igloo evolve from a hut like this one? If so, it too could be traceable to HBC, why not? Skins are a natural subsitute for leaves or grass in an environment without much vegetation. And when there's no wood around to built a framework, then ice might be the only recourse. Nevertheless, the Igloo is definitely one of the more brilliant inventions of the human mind, no question. It's also an excellent example of cultural adaptation to environmental conditions. But where there is adaptation, there must also be something that's been adapted.]
*You'll notice, by the way, that for the first time I am making an assumption, something I've avoided during the entire course of this thread. Once our (hypothetical) baseline is established, on the basis of evidence and not assumptions, we are then in a much better position to make meaningful assumptions regarding associations for which solid evidence may be lacking, at least for now. Indeed, such assumptions are useful as the basis for future research.
