That's a very late specimen, and in fact one which "led scientists to speculate that he was involved in copper smelting", hardly typical of revolutionary timescales. In evolutionary timescales, agriculture and permanent houses are a dot in the timeline, there were no longhouse dwellers for 95% of homo sapiens' history, and none at all for hominids before homo sapiens. They were nomadic foragers.
