A new analysis of charcoal recovered from one of the oldest known sites of controlled fire use argues that early humans chose their lakeside home roughly 800,000 years ago for a strikingly practical reason: easy access to driftwood fuel. The site, Gesher Benot Ya’aqov in Israel, has long been recognized as a key location for understanding when hominins began using fire. But the latest research shifts the focus from fire itself to the question of why these ancient people settled where they did, suggesting that a steady supply of burnable wood washing ashore shaped where they lived, cooked, and returned across generations.
Driftwood as a driver of hominin settlement at GBY
The core finding centers on a large charcoal assemblage from Gesher Benot Ya’aqov, an Acheulian lakeshore site dated to approximately 780,000 to 800,000 years ago. Researchers analyzed the wood species represented in the charcoal and found that fuel selection largely tracked local availability rather than reflecting deliberate long-distance foraging for preferred species. In other words, these hominins burned what was nearby, and what was nearby was driftwood carried to the lakeshore by water. The authors argue that the composition of burned wood, as documented in a recent charcoal study, matches what would be expected from material delivered by currents and waves.
That pattern carries a significant implication. If early humans were not traveling far to gather specific types of timber, then the lakeshore itself was the resource. Driftwood accumulates along shorelines through natural processes, collecting fallen branches and trunks from upstream forests and depositing them in predictable zones. For a group that had mastered fire but lacked sophisticated transport technology, a location where fuel arrived on its own would have been an enormous advantage. The charcoal record at GBY supports exactly this reading: the species composition of burned wood mirrors what would have washed up rather than what grew in the surrounding upland forest.
This reframes the settlement decision. Rather than viewing the lakeshore as attractive primarily for water, fish, or defensive terrain, the evidence points to firewood supply as a central factor. The two advantages are not mutually exclusive, of course. But the charcoal data offers the first direct evidence that fuel logistics shaped where these hominins chose to camp repeatedly over long periods. By treating driftwood as a predictable, renewable resource, the GBY inhabitants may have reduced the time and energy costs associated with gathering fuel, freeing them to focus on food procurement and tool production.
The argument is strengthened by the observation that the charcoal assemblage includes a mix of species that would not all have grown together in a tight radius around the site. Instead, the diversity of woods suggests inputs from different habitats along the drainage feeding the paleo-lake. This pattern aligns with drift transport rather than local cutting, reinforcing the idea that waterborne logs and branches were central to the fire economy of the site.
Repeated fire use and fish cooking across occupation levels
The driftwood finding gains force when placed alongside the broader fire record at GBY. A 2004 study published in Science documented burned flint and plant remains in spatial patterns consistent with hearth-related activity at the site, dating controlled fire use to around 790,000 years ago. Later work established that fire use at GBY was not a one-time event. Evidence of burning appears across multiple archaeological levels, indicating that hominins returned to this spot and made fires again and again over what likely amounted to thousands of years.
A separate study of fish remains from the site added another dimension. Analysis of fish teeth showed exposure to heat consistent with cooking roughly 780,000 years ago, making GBY one of the earliest known locations where food preparation involved fire. The researchers behind this work used microscopic and chemical signatures in the enamel to distinguish between natural burning and controlled heating, concluding that the teeth had been subjected to temperatures typical of hearths rather than wildfires. Their findings, published as a study of early fish cooking, situate GBY at the forefront of culinary behavior in the archaeological record.
Taken together, these lines of evidence describe a site where hominins had reliable fuel, used it to maintain hearths, and applied that fire to process food. The driftwood interpretation ties these behaviors together: a dependable fuel source made repeated cooking possible, which in turn made the lakeshore worth returning to. In this view, Gesher Benot Ya’aqov functioned as a long-lived “fire hub,” where technology, ecology, and subsistence strategies intersected.
Spatial and thermoluminescence analyses have further characterized the intensity of burning at GBY, distinguishing between areas where fire was concentrated and areas that saw little heat exposure. These patterns are consistent with organized hearth use rather than random or accidental burning, reinforcing the picture of deliberate, sustained fire management tied to a location chosen at least partly for its fuel supply. The structured distribution of burned materials suggests that hominins understood how to maintain and contain fire, an ability that would have been particularly advantageous at a site with constant access to new wood.
Open questions about driftwood-driven site selection beyond GBY
The GBY charcoal record is compelling for a single site, but the broader question it raises remains unanswered. If driftwood availability genuinely drove lakeshore selection, then other Acheulian sites near ancient water bodies should show a similar pattern: charcoal species that match shoreline drift deposits rather than the standing timber of the surrounding area. That prediction is testable through re-analysis of existing charcoal collections from other Levantine sites near paleo-lakes and rivers, as well as new sampling strategies that target likely drift accumulation zones.
To extend the argument, researchers would need to pair botanical identifications with reconstructions of ancient hydrology. River flow, shoreline configuration, and seasonal flooding all affect where wood is deposited. A comparative framework, drawing on the same analytical approaches used in the GBY charcoal work and in related Quaternary reviews, could test whether driftwood-driven fuel economies were common or exceptional in the Early and Middle Pleistocene.
Several gaps in the evidence also limit how far the conclusions can be pushed. The charcoal assemblage documents which species were burned but cannot directly prove that hominins chose GBY because of driftwood rather than discovering the fuel advantage after settling for other reasons, such as proximity to water, raw materials, or prey. Establishing causation, as opposed to correlation, between fuel access and site selection would require evidence that hominins bypassed otherwise suitable locations that lacked driftwood accumulation, or that they modified settlement patterns in response to changes in shoreline deposition over time.
The fish-cooking evidence, while striking, rests on heat-exposure signatures in teeth without accompanying raw isotopic or histological data tables available for independent verification in the public domain. The spatial analyses of hearth patterns rely on published summaries rather than full stratigraphic field logs. None of these limitations invalidate the findings, but they define the boundaries of what the current record can support. Future work that integrates microstratigraphy, experimental burning studies, and more transparent data sharing could sharpen the picture of how fire was used and supplied at GBY.
What the GBY research does establish, with unusual clarity for such an ancient site, is that fuel was not an incidental background factor in early human life. Instead, it appears as a structuring element in where people lived, how often they returned, and what kinds of activities they carried out. By highlighting driftwood as a key resource, the new charcoal analysis invites archaeologists to look beyond stone tools and animal bones when reconstructing hominin behavior. In the quiet record of charred wood fragments, it suggests, lie clues to the decisions that tethered early humans to particular landscapes and to the fires that illuminated their lakeside camps.
