What Were the Earliest Methods of Firemaking and Where Did They Appear?/info

Introduction

The control of fire is widely regarded as one of the most consequential technological transitions in human evolution. Fire provided warmth, protection from predators, light for extending activity into the night, and — crucially — the ability to cook food, which may have driven significant changes in hominin anatomy and brain size. Yet the distinction between the use of fire (maintaining a naturally occurring flame) and the making of fire (intentionally generating ignition) is fundamental, and the latter is far more difficult to identify in the archaeological record.

The transition from opportunistic fire use to deliberate firemaking represents a qualitative cognitive leap. Maintaining a fire captured from a lightning strike or a wildfire requires only the recognition that fire is useful and the ability to feed it fuel. Making fire from scratch requires causal reasoning, knowledge of appropriate materials (tinder, fuel, and an ignition source), and mastery of one of two basic physical principles: friction (generating heat through rapid mechanical rubbing of wood on wood) or percussion (striking a hard stone against an iron-bearing mineral to produce incandescent sparks). Recent archaeological discoveries, particularly from Barnham in Suffolk, England, have pushed the earliest evidence for intentional percussion firemaking back to approximately 400,000 years before the present.

The evidence for early fire is stratified: the oldest plausible evidence for fire use (not necessarily firemaking) comes from Wonderwerk Cave in South Africa at approximately 1 million years before the present. Habitual fire use in Europe is documented from approximately 400,000 years before the present onward. Evidence for intentional firemaking — in the form of specific "fire-making kits" involving flint and pyrite — appears in the Middle Palaeolithic and has now been tentatively identified at the Lower Palaeolithic site of Barnham. The full picture is one of a prolonged transition, spanning hundreds of thousands of years, from opportunistic scavenging of natural fires to the reliable, on-demand production of flame.

What we know

The earliest evidence for fire in association with hominins comes from sites in Africa. At Wonderwerk Cave in the Northern Cape Province of South Africa, Berna et al. (2012) identified burned bone fragments and ashed plant remains in Acheulean-age deposits approximately 1 million years old. The materials were found in situ — not washed in from the cave entrance — and had been heated to temperatures consistent with campfire conditions (200–500°C). This represents the oldest widely accepted evidence for fire use, though whether it reflects deliberate firemaking or the maintenance of naturally captured flame cannot be determined.

At Gesher Benot Ya'aqov in Israel, Goren-Inbar et al. (2004) documented evidence of fire use in Acheulean deposits approximately 790,000 years old. Burned seeds, wood fragments, and flint microartifacts were found clustered in specific areas of the site, suggesting controlled fires in designated locations. The spatial patterning of burned materials — distinct concentrations rather than random scatter — argued for intentional rather than natural fire.

Roebroeks and Villa (2011) conducted a systematic review of European fire evidence and concluded that habitual fire use did not become a consistent feature of the hominin behavioural repertoire until the second half of the Middle Pleistocene, roughly 400,000 to 300,000 years before the present. Before this period, evidence for fire in Europe is sparse and contested. After it, fire features appear regularly at sites across the continent, suggesting a threshold in either the ability to make fire or the social organisation to maintain it.

The question of how fire was made is addressed most directly by microwear analysis of stone tools. Sorensen, Claud, and Soressi (2018) examined bifaces from several late Middle Palaeolithic (Neanderthal) sites in France and identified microscopic wear traces consistent with striking against pyrite or marcasite — iron-bearing minerals that produce hot sparks when struck with flint. The wear pattern was distinctive and could be experimentally replicated: directional percussion marks, sub-parallel striations, and iron-oxide residues on the flat surfaces of handaxes. This study provided the first direct evidence that Neanderthals used the percussion method of firemaking.

The cognitive dimensions of firemaking have been explored by Shimelmitz et al. (2023) in a study titled "Minds on Fire." They argue that percussion firemaking — striking flint against pyrite — is a conceptually demanding task requiring an understanding of causal chains that is not required for friction fire. The firemaker must understand that striking two specific materials together produces an invisible intermediary (a spark) that can be captured in prepared tinder and coaxed into flame. This chain of causation is not observable in a single step and must be mentally modelled.

The 2025 study published in Nature by Ashton et al. represents the most significant recent finding. At the Acheulean site of Barnham in Suffolk, England, two fragments of iron pyrite were recovered from a 400,000-year-old occupation layer alongside hearth features (baked sediment, heat-shattered flint artefacts). Pyrite is not naturally occurring in the local geology, implying that it was deliberately imported. If confirmed as a firemaking material, this would push the evidence for intentional percussion firemaking back to the Lower Palaeolithic and associate it with Homo heidelbergensis rather than Neanderthals.

Ethnographic data provide context for the range of firemaking methods used historically. Of 164 recent hunter-gatherer groups surveyed by Shimelmitz et al. (2023), friction methods (fire drill, fire plough, fire saw) were far more common than percussion methods. Only nine groups used percussion exclusively, while 31 combined both methods. The dominance of friction fire in the ethnographic record contrasts with the predominance of percussion evidence in the Palaeolithic archaeological record, probably because friction fire leaves fewer durable traces (wood components decay) while percussion fire leaves identifiable residues (pyrite fragments, iron-oxide staining on flint).

The bow drill, the most efficient friction device, is documented ethnographically across a wide range of environments but has no confirmed Palaeolithic exemplars. The earliest direct evidence for friction-based firemaking (fire drills or similar devices) comes from much later contexts — the Neolithic and Bronze Age — though this absence likely reflects preservation bias rather than true absence in earlier periods.

Classification of theories

A. Plausible explanations (supported by evidence, not refuted):

1. Percussion firemaking (flint-on-pyrite) as the earliest method: The archaeological evidence — pyrite fragments, iron-oxide residues on bifaces, microwear patterns — consistently points to percussion as the documented Palaeolithic method. The Barnham discovery (400,000 years before the present) and the Neanderthal biface evidence (~50,000 years before the present) bracket a long tradition. This method produces incandescent iron particles that can ignite prepared tinder.

1. Gradual transition from fire use to firemaking over hundreds of thousands of years: The evidence supports a prolonged period during which hominins used naturally occurring fire before developing the ability to produce it on demand. Sites like Wonderwerk Cave (1 million years) show fire use; sites like Barnham (400,000 years) may show firemaking. The gap is consistent with a gradual cognitive and technological evolution.

1. Multiple independent inventions of firemaking: Given the geographic and temporal spread of early fire evidence — from South Africa to Israel to England to France — it is likely that firemaking was invented independently by different hominin populations in different places and times.

B. Possible explanations (raised by researchers, less well supported):

1. Friction fire predates percussion fire but is archaeologically invisible: It is plausible that simple friction methods (e.g., rubbing sticks) were used before percussion methods were developed, but all organic components would have decayed. This hypothesis is consistent with ethnographic data but currently untestable archaeologically.

1. Fire maintenance as a social technology predating firemaking by hundreds of thousands of years: Some researchers propose that hominins maintained fires for tens of thousands of years — passing flame from camp to camp — before learning to make fire from scratch. This would explain the long gap between the earliest fire evidence (1 million years) and the earliest firemaking evidence (400,000 years).

C. Highly unlikely but argued by some:

1. Firemaking as a very recent invention (Upper Palaeolithic or later): Some older accounts argued that only modern humans could make fire and that earlier hominins merely used captured natural fires. The microwear evidence from Neanderthal bifaces (Sorensen et al., 2018) and the Barnham pyrite discovery (Ashton et al., 2025) have effectively refuted this view.

Landmark Studies

1. Berna, F. et al. (2012). "Microstratigraphic evidence of in situ fire in the Acheulean strata of Wonderwerk Cave, Northern Cape province, South Africa." Proceedings of the National Academy of Sciences, 109(20), E1215–E1220. Full text: https://www.pnas.org/doi/10.1073/pnas.1117620109 [open access]

[Publisher abstract] Here we show that micromorphological and Fourier transform infrared microspectroscopy (mFTIR) analyses of intact sediments at the site of Wonderwerk Cave, Northern Cape province, South Africa, provide unambiguous evidence — in the form of burned bone and ashed plant remains — that burning took place in the cave during the early Acheulean occupation, approximately 1.0 Ma.

Full-text notes: Berna et al. used micromorphological thin sections and infrared spectroscopy to demonstrate that burned materials in Wonderwerk Cave were heated in situ, not transported from outside. The burned bone fragments showed colour changes and structural alterations consistent with heating to 200–500°C, typical of campfire temperatures. The ashed plant remains were identified as grass or sedge tissues.

The critical argument for human agency (rather than natural wildfire) is spatial: the burned materials are found deep within the cave, approximately 30 metres from the entrance, in deposits that show no evidence of water transport or slope wash. Natural fires would be unlikely to penetrate this far into a cave. However, the authors are careful not to claim firemaking; the evidence is consistent with fire maintenance — bringing a naturally captured flame into the cave.

This study pushed the accepted date for controlled fire use back by several hundred thousand years and remains the earliest well-supported evidence for fire in a hominin context.

[Publisher abstract] The presence of burned seeds, wood, and flint at the Acheulian site of Gesher Benot Ya'aqov in Israel is suggestive of the control of fire by humans nearly 790,000 years ago.

Full-text notes: Goren-Inbar et al. documented repeated occurrences of burned materials across multiple occupation layers at this Acheulean lakeside site. The spatial clustering of burned microartifacts — small flint fragments heated to temperatures above 400°C — in discrete areas of each layer was interpreted as evidence of designated hearth locations. The presence of burned plant seeds (olives, barley, wild grape) alongside burned wood and flint suggested fire use in the context of food processing.

The site's age (~790,000 years) and the repeated, spatially patterned evidence across multiple layers strengthened the case that this represented habitual controlled fire use rather than a single opportunistic event. The study was a landmark in establishing that fire use was a regular part of the Acheulean behavioural repertoire in the Levant.

[Publisher abstract] The timing of the habitual use of fire is a hotly debated issue, with claims for regular fire use by early hominins in Africa at ~1.6 million years ago. Here we review the evidence for early fire use in Europe.

Full-text notes: Roebroeks and Villa conducted a critical review of all claimed European fire sites older than 400,000 years and found that none met rigorous evidential standards for in situ burning. They concluded that habitual fire use in Europe dates to approximately 300,000–400,000 years before the present, associated with Homo heidelbergensis and early Neanderthals. Before this date, European hominins either did not use fire or used it so sporadically that it left no consistent archaeological signature.

The paper is significant for establishing a methodological standard: evidence for fire must include in situ burned materials, spatial patterning suggesting hearth structures, and exclusion of natural explanations (wildfire, volcanic activity). By applying these criteria rigorously, Roebroeks and Villa clarified the timeline and set the stage for subsequent discoveries.

[Publisher abstract — extracted from article] We report on systematic microwear analysis of late Middle Palaeolithic bifaces from several sites in France and identify mineral use-wear traces consistent with the use of these tools to strike sparks from pyrite for firemaking.

Full-text notes: Sorensen et al. conducted experimental replication of percussion firemaking using replica bifaces and pyrite, then compared the resulting microwear with traces on actual 50,000-year-old Neanderthal handaxes from French Mousterian sites. The match was compelling: directional percussion marks, C-shaped impact points, sub-parallel striations, and iron-oxide residue were present on both experimental and archaeological specimens.

The study identified these firemaking traces on bifaces from multiple sites, suggesting that percussion firemaking was a widespread Neanderthal practice, not an isolated occurrence. The use of bifaces (handaxes) as fire-strikers challenges the common assumption that bifaces were primarily cutting tools; they appear to have been multi-purpose implements.

This paper is the first to provide direct, artefact-based evidence for a specific firemaking technique in the Palaeolithic. Previous evidence had been circumstantial (presence of hearths, association with burned materials). The microwear approach offers a new analytical window into a behaviour that is otherwise invisible.

Full text: https://www.cambridge.org/core/journals/cambridge-archaeological-journal/article/minds-on-fire-cognitive-aspects-of-early-firemaking-and-the-possible-inventors-of-firemaking-kits/CF76FFCF540D58B6B1DACF17C4A51C94 [publisher paywall]

[Agent-generated summary] This study examines the cognitive demands of percussion versus friction firemaking, surveys the ethnographic distribution of firemaking methods, and argues that percussion fire (flint-on-pyrite) was the earliest documented method. The authors contend that the conceptual chain required — understanding that an invisible spark can be captured to produce flame — represents a significant cognitive achievement.

Full-text notes: Shimelmitz et al. tabulated firemaking methods across 164 ethnographic hunter-gatherer groups, finding that friction fire (especially fire drills) is the dominant method globally but that percussion fire has deep antiquity in the archaeological record. They argue that early percussion firemaking used unspecialised flint tools — any sharp-edged stone struck against pyrite could generate sparks — and that formalised "fire-making kits" (dedicated strike-a-lights) appeared only later.

The cognitive analysis distinguishes firemaking from other Palaeolithic technologies. Stone-tool knapping requires spatial planning and motor skill but involves a direct, visible transformation (striking produces a flake). Firemaking requires understanding an invisible intermediate (the spark) and a multi-step causal chain (spark → tinder → flame → fuel). The authors suggest this cognitive capacity was present by the Middle Palaeolithic and possibly earlier.

Recent Studies

6. Ashton, N. et al. (2025). "Earliest evidence of making fire." Nature. Full text: https://www.nature.com/articles/s41586-025-09855-6 [publisher paywall]

[Agent-generated summary] Report of baked sediment, heat-shattered flint artefacts, and two fragments of imported iron pyrite at the 400,000-year-old Acheulean site of Barnham, Suffolk, England. The authors argue that the pyrite — non-local to the site geology — was brought there for the purpose of firemaking by percussion, representing the earliest known evidence of intentional fire production.

Full-text notes: The Barnham discovery is significant because the co-occurrence of pyrite fragments with hearth features in a deposit where pyrite does not naturally occur constitutes circumstantial but compelling evidence for intentional firemaking. The pyrite fragments are small (~2 cm) and show no signs of having been used as tools for other purposes. Their presence in a hearth context, alongside baked sediment and thermally fractured handaxes, is best explained as a fire-making kit.

If the interpretation holds, this finding pushes percussion firemaking back from the Middle Palaeolithic (~50,000 years, Neanderthals) to the Lower Palaeolithic (~400,000 years, Homo heidelbergensis), extending the tradition by 350,000 years. The site's association with Acheulean technology — large bifacial handaxes — further supports the idea that these tools were used as fire-strikers as well as cutting implements.

7. Alperson-Afil, N. (2017). "Spatial analysis of fire: archaeological approach to recognizing early fire." Current Anthropology, 58(S16), S258–S266. Full text: https://doi.org/10.1086/692721 [publisher paywall]

[Agent-generated summary] Alperson-Afil develops spatial analytical methods for identifying controlled fire use in Palaeolithic sites, using the distribution of burned microartifacts as a proxy for hearth location and intensity. Applied to Gesher Benot Ya'aqov and other Acheulean sites.

Full-text notes: This methodological paper demonstrates that even in the absence of preserved hearth structures, the spatial distribution of small burned flint fragments can reveal the locations of past fires. By mapping the density and temperature of heating of these microartifacts, Alperson-Afil shows that Acheulean sites often contain multiple discrete fire locations within a single occupation layer, supporting the interpretation of repeated, intentional fire use.

The approach is particularly valuable for open-air sites where organic materials (charcoal, ash) have not survived. It provides a complementary line of evidence to the microwear analysis of Sorensen et al. and the sediment chemistry of Berna et al.

8. MacDonald, K. et al. (2021). "Middle Pleistocene fire use: The first signal of widespread cultural diffusion in human evolution." Proceedings of the National Academy of Sciences, 118(31), e2101108118. Full text: https://www.pnas.org/doi/10.1073/pnas.2101108118 [publisher paywall]

[Agent-generated summary] The authors analyse the spatial and temporal distribution of fire evidence across Africa, the Levant, and Europe and argue that the widespread adoption of habitual fire use around 400,000 years before the present represents the first archaeologically visible instance of cultural diffusion in human evolution — a behaviour spreading across populations through social learning rather than independent invention.

Full-text notes: MacDonald et al. show that evidence for fire use increases dramatically and nearly simultaneously across multiple regions between 400,000 and 300,000 years before the present. They argue that this synchrony is best explained by cultural transmission rather than independent invention, and that fire use may have spread along the same corridors used by hominin populations for migration and exchange.

The implication is that firemaking (or at minimum, techniques for reliable fire maintenance) was a socially transmitted technology — one of the earliest examples of cultural knowledge that spread across geographic boundaries. This connects the fire question to broader debates about the origins of cumulative culture.

Future Research Directions

The most pressing need is for additional sites with co-occurring pyrite and hearth features from the Lower and early Middle Palaeolithic. The Barnham discovery is currently a single data point; confirmation from independent sites would transform it from a suggestive anomaly into established fact. Systematic screening of existing Acheulean and Mousterian collections for pyrite fragments and iron-oxide residues on bifaces could yield additional evidence without new excavation.

Experimental archaeology has a crucial role to play. While Sorensen et al. (2018) replicated percussion firemaking with bifaces and pyrite, more extensive experiments — varying pyrite quality, tinder types, ambient humidity, and operator skill — are needed to establish the reliability and efficiency of the technique. Comparisons with friction methods under the same conditions would help assess whether percussion fire was a preferred method or a last resort.

The development of chemical fingerprinting techniques for distinguishing burned pyrite residues from naturally occurring iron oxides would strengthen the evidential chain. If a spectroscopic signature unique to percussion-fire residues could be established, it could be applied to stone-tool collections across the Palaeolithic, potentially revealing a much wider distribution of the practice than currently recognised.

The relationship between firemaking and other cognitive capacities — tool manufacture, spatial planning, social learning — deserves further theoretical development. Shimelmitz et al. (2023) have begun this work, but a more detailed cognitive-archaeological model of the steps involved in firemaking, and their overlap with the cognitive demands of other Palaeolithic technologies, could clarify when and why firemaking became possible.

Finally, the connection between fire control and human biological evolution — the "cooking hypothesis" advanced by Wrangham (2009) — requires continued testing. If firemaking (as opposed to fire use) was achieved only around 400,000 years before the present, this post-dates the major anatomical changes (brain expansion, gut reduction) that Wrangham attributes to cooking by several hundred thousand years. This timing discrepancy suggests either that fire use (without making) was sufficient to drive the biological changes, or that the archaeological record of early firemaking is still grossly incomplete.

Summary of Existing Research and Public Opinion

The scientific consensus recognises a distinction between fire use and firemaking that is often lost in popular accounts. Fire use — maintaining and transporting naturally occurring fire — is documented from approximately 1 million years before the present. Firemaking — generating fire from scratch — is documented with reasonable confidence from approximately 400,000 years before the present (percussion method using pyrite) and with high confidence from the Middle Palaeolithic (~50,000 years before the present).

Public awareness of early fire tends to be shaped by the cooking hypothesis: the idea, popularised by Wrangham's Catching Fire (2009), that cooking drove human brain evolution. While this hypothesis is influential and well-argued, it conflates fire use with firemaking and assumes reliable fire access earlier than the current evidence supports. The public also tends to imagine friction fire (rubbing sticks together) as the primordial method, whereas the archaeological evidence points to percussion fire (flint on pyrite) as the earliest documented technique.

Among specialists, the field is experiencing a period of rapid progress. The Barnham discovery (2025) and the Neanderthal microwear evidence (2018) have provided the first direct evidence for specific firemaking techniques, moving the discussion beyond the presence or absence of hearths to the methods and cognition involved. The integration of experimental archaeology, microwear analysis, and spatial statistics is producing a more detailed and nuanced picture than was possible even a decade ago.

The question of when hominins first made fire is not yet definitively answered, and the answer will almost certainly continue to shift as new evidence is recovered. What is clear is that the control of fire — in some form — was a deep and ancient part of the hominin behavioural repertoire, predating the emergence of Homo sapiens by hundreds of thousands of years.

Where Do I Come In?

Fire is one of the great themes in the story of human evolution, and observatory.wiki is well positioned to provide a guide that cuts through the popular simplifications. The distinction between fire use and firemaking is fundamental and rarely explained clearly in non-specialist sources. A well-constructed document can help readers understand why this distinction matters: fire use requires only recognition and maintenance; firemaking requires causal reasoning, material knowledge, and skilled execution.

The Barnham discovery and the Sorensen et al. microwear findings are perfect subjects for observatory.wiki's approach: technically significant results that have not yet been widely assimilated into public understanding. Explaining the microwear methodology — how scratches on a 50,000-year-old handaxe can reveal that it was used to strike sparks from pyrite — is the kind of "how do we know what we know" content that expert-facing guides do best.

The ethnographic data on firemaking methods offer a point of entry for readers who are not specialists in Palaeolithic archaeology. The contrast between the modern dominance of friction fire and the Palaeolithic dominance of percussion fire is inherently interesting and raises questions about technological change, cultural transmission, and the preservation biases that shape the archaeological record.

For readers interested in the broader implications, the fire question connects to nutrition (the cooking hypothesis), cognition (the mental demands of firemaking), social organisation (the transmission of fire-related knowledge), and climate adaptation (fire as a tool for surviving cold environments). A guide document that traces these connections — without overreaching the evidence — would serve as a valuable hub within observatory.wiki's network of human-origins content.

The field is moving quickly, and the next decade is likely to produce significant new evidence, particularly as microwear analysis and chemical fingerprinting are applied more widely to existing collections. Observatory.wiki can serve as a living document, updated as new findings emerge, providing readers with a reliable and current synthesis of one of the most fundamental questions in human evolutionary history.
