Complexity scientist Peter Turchin and his team at CSH, working as part of an international and interdisciplinary collaboration, may have added a meaningful piece to a long-standing puzzle in archeology. Scholars have long tried to understand why Neolithic farmer populations go through boom-bust cycles, including “collapses” when whole regions are abandoned.
According to one common explanation, climate fluctuations are the main driver, but empirical tests do not fully support this claim. In a new paper, published in the latest issue of Nature Scientific Reports, Turchin and his team seem to have come up with a new piece of information.
“Our study shows that periodic outbreaks of warfare — and not climate fluctuations – can account for the observed boom-bust patterns in the data,” argues Turchin, who’s a project leader at the Complexity Science Hub (CSH).
