The remains of a couple of nearly 20,000-year-old huts, excavated in a Jordanian desert basin, add to evidence that hunter-gatherers built long-term dwellings 10,000 years before farming villages debuted in the Middle East.
These new discoveries come from a time of social transition, when mobile hunter-gatherers hunkered down for months at a time in spots that featured rivers, lakes and plentiful game, say archaeologist Lisa Maher of the University of California, Berkeley and her colleagues.
