there's a very important factor that you are overlooking. Most human settlements are in river valleys. IOW's most human settlements are not built on a solid foundation.

as for 'Primitive' techniques. I find your generalisations to contain far to many contradictions to be viable. As someone who has built , or participated in the building of a teepee, a log home, an A-Frame, a treehouse, a sod hut, an igloo, a standard modern stud and clap board home, and has graded lumber for the Japanese skeletal frame type of construction I can attest that the varialble is not technique per se, but quality of workmanship and materials combined with the proper choice of structure for the location.

The AE's had lots of mud. They used stone for those structures that needed to be permanent.
