Ancient Wildfires May Have Sparked Pottery’s Birth in the Southern Levant

Study Overview
A study published in early September in *Geomorphology* analyzes sediment, cave deposits, charcoal layers and archaeological sites across the southern Levant. Lead researcher Prof. Amos Frumkin of the Hebrew University of Jerusalem’s Institute of Earth Sciences proposes the “natural kiln hypothesis”: Neolithic communities may have learned to fire clay after observing natural wildfires that hardened the material.
Environmental Context
The research compares two intervals of major environmental instability.
- Last interglacial (MIS 5e) – roughly 129,000 to 116,000 years ago.
- Early Holocene – approximately 11,000 to 7,000 years ago, with the most intense fire-erosion episode dated to about 9,500-8,200 years ago.
In both periods, charcoal particles preserved in ancient lake sediments record peaks in burning, while chemical signatures in speleothems indicate extensive vegetation loss and soil erosion. Fires stripped hillsides of vegetation, exposing clay-rich soils that were then washed into depressions such as the Jordan and Dead Sea valleys, creating fertile, clay-laden basins.
Evidence and Findings
- Tiny charcoal fragments and erosion markers demonstrate that large-scale wildfires were followed by rapid runoff of terra rossa clay into low-lying valleys.
- Petrographic analysis shows that Yarmukian pottery from the Jordan Valley was made from this locally redeposited clay.
- Pottery appears in the archaeological record during the early Holocene, coinciding with the peak of fire-driven clay deposition.
- By contrast, despite a similar “natural experiment” during the last interglacial, no pottery is found, which the authors attribute to the earlier populations’ limited cognitive and social capacities.
Official Interpretation
Prof. Frumkin frames the hypothesis as speculative and testable, emphasizing that the observed sequence of natural fires, erosion, and clay exposure could have offered Neolithic people a model for intentional firing.
Implications
If the natural kiln hypothesis holds, it would illustrate how a major technological breakthrough—pottery—could emerge from direct observation of environmental processes, highlighting the role of ecological disruption in early human innovation.
