Who Started the First Fire?

Who Started the First Fire?

In the 1981 movie Quest for Fire, a group of Neanderthals struggles to keep a small ember burning while moving across a cold, bleak landscape. The meaning is clear: If the ember goes out, they will lose their ability to cook, stay warm, protect themselves from wolves—in short, to survive. The film also makes it obvious that these Neanderthals do not know how to make fire.

During the Middle Paleolithic, roughly 250,000 to 40,000 years ago, when Neanderthals occupied Europe and much of western Asia, the climate included a couple of major warm periods similar to today, but was dominated by two major cold periods that included dozens of shifts between cold and very cold conditions. Quest for Fire presented a generally accurate portrayal of Europe during one of the cold periods (80,000 years ago, according to the film’s title card), but almost all researchers agreed that the movie was flat-out wrong in its suggestion that Neanderthals were incapable of making fire. Now, new fieldwork our team has done in France contradicts some long-held assumptions and shows that the film might have had it right all along.

Conventional thinking has long held that our human ancestors gained control of fire—including the ability to create it—very early in prehistory, long before Neanderthals came along some 250,000 years ago. For many researchers, this view has been supported by the discovery of a handful of sites in Africa with fire residues that are more than a million years old. But it has also been buoyed by the simple logic of one idea: It is hard to imagine that our ancestors could have left Africa and colonized the higher, and often much colder, latitudes of Europe and Asia without fire.

The Neanderthals, after all, lived in Europe during multiple periods in which seasonal temperatures were similar to those that exist today in northern Sweden. (Northern Europe was covered in massive ice sheets during those periods.) There were vast, frigid grasslands populated by herds of reindeer, horses, and woolly mammoths. Fire would have allowed Neanderthals to cook those animals, making the meat easier to chew and more nutritious. And, perhaps more importantly, it would have helped the Neanderthals stay warm during the coldest periods.

This line of thought is the basis for the long-prevailing notion that our ability to make fire began long before the Neanderthals, as a spark—a single technological discovery that spread widely and quickly and has remained essential to human life, in an uninterrupted line, to the present day. But more recent evidence—some of it coming from our own fieldwork—indicates that hominins’ use of fire was not marked by a single discovery. It more likely consisted of several stages of development, and while we don’t yet know when these stages occurred, each of them may have lasted for hundreds of thousands of years.

We surmise that during the first stage, our ancestors were able to interact safely with fire; in other words, instead of simply running from it, they had become familiar with how it works. To get a deeper understanding of this stage, we can look to research done on chimpanzees—our closest living relatives—by Jill Pruetz, a primatologist at Iowa State University, who has studied chimps’ interaction with wildfires in West Africa. Pruetz has found that chimps clearly understand the behavior of fire enough to have lost the fear of it that most animals typically possess. In fact, Pruetz has observed chimps monitoring the progress of a passing wildfire from a few meters away and then moving in to forage in the burned-out area. So while chimps cannot build or contain fires, they understand how fire moves across the landscape, and they use this knowledge to their benefit. It is not hard to imagine a similar scenario playing out among small groups of our own early ancestors, perhaps the australopithecines, who lived from around 4 million years ago until about 2 million years ago in East Africa. The first stage may have persisted throughout much of prehistory.

The second stage would be when people could actually control fire—meaning they could capture it, contain it, and supply it with fuel to keep it going within their living areas—but they were still obtaining it from natural sources like forest fires. It is difficult to establish when this stage occurred, for a couple of reasons. One is that some claims for very old fires were simply incorrect. For example, at the famous Chinese site Zhoukoudian, what were originally thought to be the remains of 700,000-year-old Homo erectus fires turned out to be natural sediments resembling charcoal and ash.

Second, and perhaps most crucial, is that some of the earliest fire residues have been found in open-air settings—not inside caves—and consist of isolated fragments, small scatters of burned bones, or patches of discolored sediments. While it is possible that these residues are the remains of hominin campfires, it is equally possible, if not probable, that they were produced by naturally occurring wildfires. Every year, lightning causes tens of thousands of wildfires across Africa, Asia, and Europe. In the past, some of these would have burned the remains of hominin camps, including bones, stone tools, and sediments. In such cases, the fire residues have nothing to do with hominin occupation of the sites.

During the final stage, humans learned how to make fire, but again, we are not yet sure when this happened. Starting about 400,000 years ago, we begin finding much better evidence for human-controlled fire, such as intact campfires, or “hearths,” that contain concentrations of charcoal and ash inside caves, where natural fires don’t burn. Furthermore, the number of sites with such evidence increases dramatically. So it is clear that by this time, some hominins in some regions could manage fire and thereby control it, but whether they could make it remains an open question.

Between 2000 and 2010, our research team—made up of three Paleolithic archaeologists who focus on stone tool technology and two geoarchaeologists who study how archaeological sites form—excavated two Middle Paleolithic sites, Pech de l’Azé IV and Roc de Marsal, in the Périgord region of southwestern France. Pech IV and Roc de Marsal are caves that were regularly used as campsites by small groups of Neanderthals from 100,000 to 40,000 years ago, which is about when Homo sapiens, modern humans, arrived in Europe.

Neanderthal fire - Experiments show that fires leave behind evidence—charcoal, ash, and burned artifacts—that gets buried under layers of sediment that accumulate over time, leaving a record that can persist for many thousands of years.

One of the more interesting discoveries we made during our years of excavating Pech IV was strikingly abundant evidence of fire use. In the lowermost deposits, those resting directly on the cave’s bedrock floor, we found a 40-centimeter-thick layer full of charcoal, ash, and burned artifacts marking where individual campfires had been built 100,000 years ago. There were also thousands of stone tools, many of which had been incidentally burned by nearby fires. (Paleolithic people were producing, using, and discarding stone tools on a daily basis, so their occupation sites are full of these artifacts—along with bone fragments from their prey animals—which were eventually buried under sediments that accumulated over time. Later people who used the sites could not help but build their fires on top of concentrations of discarded tools and bones.)

We found similar evidence at Roc de Marsal, which also has a thick sequence of successive layers containing tens of thousands of stone tools and the bones of butchered animals. Just as at Pech IV, the oldest layers at Roc de Marsal contained abundant evidence of fire, including dozens of intact hearths so well-preserved that they looked like they could have been abandoned just days before.

We were not surprised to find signs of fire at these two sites, since other, even older sites also offered good evidence of fire. And given the prevailing notion of a spark—that once fire-making was “discovered” it quickly became part of everyday life—we simply assumed that the Neanderthals at Pech IV and Roc de Marsal knew how to make fire.

However, other evidence from these sites soon led us to question that notion. For one, neither site showed signs of fire in its upper layers. At first, we speculated that since Paleolithic people tended to live right at the mouths of caves, wind or water had removed the fires’ ephemeral traces, like charcoal and ash. At the same time, however, almost none of the thousands of stone tools and animal bones we found in these upper layers were burned. If fire had been present, these objects would have been altered by the heat. Erosional processes like wind and water, after all, cannot selectively remove burned objects and leave behind unburned ones. It was clear, then, that fire had almost never been used at these sites in the later periods.

Neanderthal fire - Research conducted at Roc de Marsal revealed that the oldest layers of occupation contained abundant evidence of fire.

This seemed strange, especially because the older layers dated to a warm climatic period, while the more recent layers—the ones without fire—were deposited between 70,000 and 40,000 years ago, a time of increasing cold as glaciers again spread across much of Europe. This raised some really interesting questions: Why did Neanderthals stop using fire during cold periods, when the need for warmth would be most important? And if they were using fire only in the warm periods, what were they using it for? Cooking would be one possibility, but then why did they not cook their food during the colder periods?

Having fires in warm periods and not in cold periods made little sense. It’s not just a question of having fuel available. While trees are much more common during warmer periods, animal bone, which is also an effective fuel (and was used for the fires at Pech IV), is abundant during both warm and cold periods. This leaves one possible explanation: The Neanderthals at this time were still in the second stage of interacting with fire—they were collecting naturally occurring fire when it was available but did not yet have the technology to start fires themselves.

It is well-known today that natural fires from lightning strikes occur much more frequently in warm conditions—whether in more temperate places or during warmer parts of the year. Similarly, lightning would have been much more prevalent during the warmer phases of the Pleistocene Epoch (which lasted from roughly 2.6 million years ago to around 10,000 years ago) than during the colder periods. If the Neanderthals lacked the ability to start fire themselves and could thus only obtain it from natural fires, then we would expect to find much more evidence of hearths during warmer periods and less during colder ones. Which is why it is likely that Neanderthals had not yet entered the third stage of interacting with fire. That technological development occurred either elsewhere or at a later time.

Neanderthal fire - Evidence at both Pech IV and Roc de Marsal suggests that Neanderthals did not have fire during the coldest time periods.

The evidence from Pech IV and Roc de Marsal clearly shows that the Neanderthals at these sites lived without fire not only for long periods but also during the coldest periods. This alone raises even more questions about how they were able to survive. There is no clear evidence that they could make clothing (although some researchers today seem to think Neanderthals were likely making some articles of clothing, even if they were very crude), so perhaps an old theory about Neanderthals—that they were really hairy—is correct. (This notion, from the early 1900s, was discarded in later decades because it was seen as dehumanizing Neanderthals.) It might also mean that they relied more on food—especially meat—that did not need to be cooked.

So while we are obligate fire users today—we could not survive without fire in some form—Neanderthals, according to our research, had no such dependence. Perhaps fire dependency arose later, in the Upper Paleolithic (40,000 to 10,000 years ago), and it is almost certain to have existed by the time agriculture developed at the beginning of the Neolithic period (roughly 10,000 years ago in the Middle East). But there is still much we do not know.

If chimpanzees can effectively interact with wildfires, can we assume that the same was true for some of the earliest hominins, such as Australopithecus afarensis? When did our hominin ancestors first start to collect burning material and carry it back to their campsites, as portrayed in Quest for Fire and as probably practiced by Neanderthals? And, of course, when did humans first learn how to make fire? These are just a few of the mysteries that remain unsolved.

The ability to take advantage of the properties of fire is one of the most important technological advances in our evolutionary past. What we are realizing now, however, is that it was not the result of a single accident or stroke of genius. It was, instead, a process that likely unfolded over hundreds of thousands of years. And for the Neanderthals, the process was punctuated by periods of intense cold in which, when the benefits of fire would have been greatest, they simply had to make do without it.

Toward the end of Quest for Fire, a young Homo sapiens woman teaches a small group of Neanderthals how to start a fire by using the hand-drill technique to create an ember. While it is certainly possible that modern humans developed fire-making technology before arriving in Europe, and perhaps even shared it with Neanderthals, such a scenario remains, at this point, pure speculation.

What has become clear, however, is that before Homo sapiens arrived in Europe, our Paleolithic cousins didn’t just spend a few months or years in a cold land without fire—they spent entire lifetimes, many generations even, without the warm glow of a hearth to take the chill off their toes, cook their meat, and lift their spirits.

    so perhaps an old theory about Neanderthals—that they were really hairy—is correct.

    Could genetic evidence be brought to bear on this? I am personally very hairy- a small parasite could walk from the crown of my head to the first joint of my big toe without breaking cover- and I know a few other people, all male, like this, but it’s uncommon enough for people to remark on it. Could this be due to Neanderthal genes? The strongest argument against would be that extreme hairiness is so very rare in women, but there might be other reasons for that.

  • hello world

    Whenever technological advancement is discussed it is framed as a sort of quantum leap from a darker, almost unliveable time to a more pleasant one -“flash of genius” as used here, is very typical . But is this really so? Is technology necessary for a proper, full, healthy, enjoyable life? Are animals robbed of their enjoyment of life because technology is out of their reach, or because they cannot think about life? Does a living thing need to think about life, or oneself, to enjoy its life? To champion technology is to say yes to that question isn’t it? Its to say there is something faulty about natural evolution. We need to get in there, think about it, and tinker with it. Man was a thinker when he picked up that fire and carried it back, that’s for sure. I’m sure he was projecting himself in many ways, fire being one of them, looking for improvements. He would have created a flashing, talking gps-coordinated spear at that very time, if he thought, thought being the key word, it would improve his own, personal well-being or that of his tribe. The projection of thought that brings about technology is a selfish one, since thought is always selfish, always obsessed with “me and mine”. My country and your country. Man when he became a thinker was regressing psychologically from the animal state that has no divisive psychological “I”, that does not ask for comfort or mind in the least if does not have it, to one that seeks comfort around every corner for its seekers personal comfort, who hails it a “flash of genius” when he brings this divisive state about.

    Nature provides for living things as they evolve. No one would say that nature has been rough with an animal because it did not give it a flashlight to see better – the animal, any animal including early humans, always had what they needed to live. When man picked up fire and carried it back to camp, he really had no need to do so, that is what is so puzzling. He would have had whatever adaptations he needed for food and warmth. So it is a question of incremental improvement for the sake of comfort isn’t it? And most incremental improvements man has made for the sake of comfort have come with some sort of downside, since thought is incomplete, and never can see the whole, whereas the adaptations of nature are the whole itself in microcosm, and never have unintended consequences. Picking up fire, thus fostering a dependence on exosomatic energy that now looks likely to destroy us is the ultimate example. Refrigeration was another “great leap”. However, it has reduced the fermentation of our foods, reducing our microbial exposure. Many other “advances” have also had the effect of reducing microbial exposure, a fact now being seen as potentially key to the immune dysregulation at the heart of so many of our illnesses, especially of the chronic kind. Whether it is the green revolution or the hygiene revolution, they all have come at great cost, including overpopulation and illness. Mostly they work spectacularly well for a number of decades before the costs become apparent. Those costs are the result of thought, the projection of the seeker and his self concern in time, and that seeker in projecting himself divorces himself from the whole that exists when thought, symbolic thought, does not operate. Yes still we hail this whole process of division as something incredible, ignoring all the war, all the suffering that is beyond all bounds for man and especially for the animals, that has been mans lot ever since he thought “I am”, an incomplete illusory misconception, which by the same process expressses itself in technology, which is likewise fundamentally not representative of the whole and thus fragmentary – in both the result and proof is the unintended consequences that dog technology and the psychological warfare that is human society.

      Pretty highfalutin. Raise some pigs or hunt in the wild for a year might clear up some of your complete illusory misconceptions.

      I have the idea you’ve only seen nature through the TV screen. The natural world doesn’t work that way. Animals try to exploit a niche in an environment. Their exploitation needs to return much more energy than exerted or they die. The environment must be generally suited to their residence or they die. The predator load must be below the replacement rate, or they die. The parasite load must be below the energy load, or they die. And (observe in pandas) their desire to procreate must be high enough to enable replacement numbers, or they die out.

      All in all, as far as animals are concerned, it’s a cruel world. And then you die.

    i”m looking forward to more results of dental calculus analysis. It can, among other things, indicate whether the individual whose tooth accumulated it was around fire, or ate cooked food. A recent analysis of the Sima del Elefante remains in the Atapuerca hills showed no evidence of any connection with fire at all. Now that the value of calculus is known, it should be possible to get a much more comprehensive view of which hominins did, and didn’t use fire.

    I found the whole article extremely interesting. The scenario described for the film “Quest for Fire” put me in mind of things I read a long time ago about Tasmanian Aboriginals. The accounts I read were contemporaneous with the ongoing traditional existence of aboriginals, but I am sorry, I can’t give bibliographic references. However, I am confident that if you wished to, you could readily enough verify the following.

    It stated that they carried fire with them very carefully as they travelled, so as to be able to kindle fires in their new location. As I recall, it was absolutely taboo in their society to refuse anyone who asked for a piece of fire from your hearth, even if they were traditional enemies. Consistent with all that, suppose, I did not read anything about their being able to make fire using two pieces of timber, though I understand that WAS widely practised by Mainland Australian Aboriginals (an ethnically and culturally different people). Tasmanians used archaeolithic flaked implements only and never hafted them, while at least most mainlanders had neolithic ground implements. So it may not be unreasonable to see the control by carrying of fire preceded the actual making of it de novo, hence its preciousness to Tasmaniana. Indeed, smoke from their fires (which they would never extinguish under any circumstances), was used by British settlers to locate and kill them during the notorious “Black Wars”. Which again, shows what “obligate fire users” as you put it, they were, even though they knew it could pose a mortal risk to maintain their fires.

    I should add, Tasmanians were/are definitely Homo Sapiens (or at least predominantly, like most of us), were not unduly hairy, and wore possum-fur garments and greased themselves with possum-fat against the cold, in what is still the coldest part of Australia. They survived through the last Ice Age, when substantial parts of Tasmania were glaciated.

  • Is it not equally possible that the Neanderthal was in hiding, perhaps afraid to show any light at all. They were reasonably intelligent people.

  • Meander valley

    2 caves don’t make a reality. Although the article could be right and they may not have had fire, there could also be various other explanations which people have mentioned below:
    – They were hiding from Homo Sapiens (you may have stumbled on why they died out).
    – The caves weren’t being inhabited in the same way at the later period due to the temperature
    – It wasn’t actually Neanderthals inhabiting the caves at that time – What if Homo Sapiens learned fire control from Neanderthals?

    It would be good to see tests on other caves to see if the same pattern emerges. Also, what happened in the other cold spell at an earlier period? Did you see the same drop in fire use? If yes, it either points to a lack of control of fire use, or a different living method in that weather. If you didn’t see the same drop in fire use in the earlier spell of cold weather, it points to a different reason.

    The later period could also be when they started building shelters rather than living in caves. They perhaps cut up the prey in the caves and cooked it in their shelters. It is easier to heat a shelter or tent structure and takes less fuel.

  • Richard Wilson

    How about the earliest evidence of fire use from Wonderwerk Cave at about 1.7 Ma old? Why is this not referenced in a discussion concerning fire use during the Pleistocene?

  • fnsgreen

    It was my understanding that our anatomy requires cooking of our food. Our digestion track is much shorter than other mammals and to receive the nutrition we need, before expelling it, the food must be ‘broke down’ by cooking (or decomposition – indicating scavenger behavior). This would imply a rather lengthy time for us to evolve that way wouldn’t it?

  • LeslieFish

    Are you sure that those Neanderthals didn’t just *move the fireplace* to a more relevant location, say, to the mouth of the cave, where it would scare off big predators and serve as a beacon to anyone outside? Even when the weather is cold, there are still lightning-caused fires in the summer. Anyone encountering one could easily grab enough wood or other fuel to “capture” the wildfire and carry it home, so this lack of use of older fire-pits isn’t necessarily proof that the Neanderthals in that area didn’t still use fire.
