The new Avatar movie uses fire as its theme. Fire is a transcendent part of our culture. Without fire we wouldn’t have had light, heat, create technological advantages (e.g., chemical reactions, tools), or be able to cook foods. It was especially important to early humans who probably used fire to protect them from dangerous animals. So, I got to wondering, how long has fire been a part of the human culture?
A long time, it turns out.
Scientists unearthed sediment that indicated fire might have been used in Kenya about 1.5 million years ago. Researchers suggested a red sediment could hint at early fire use. There are two sites in Israel dated approximately 800,000 years ago that had burnt animal bones and stone tools.
Archaeologists found evidence of burning at cave sites in France, Portugal, Spain, Ukraine and the U.K., and then more widespread use of fire in Europe, Africa and the Levant (the region around the east Mediterranean) 200,000 years ago.
But it is one thing to use fire and another to create it. For example, it is believed that the earliest humans may have gathered fire from natural sources (e.g., lightning strikes or forest fires). They may have stored it using certain fungi which can smolder and are portable, thereby keeping a fire going for a period of time.
Some scientists are convinced that Neanderthals were the world’s first innovators of using stone strikes to create fire, based on tiny specks of pyrite found at a more than 400,000-year-old archaeological site in Suffolk, England. (Of course, evidence of another method of creating fire, rubbing two sticks together, would not survive.)
The Barnham dig site in England yielded stone tools, burnt sediment and charcoal from 400,000 years ago. In a study published in the journal Nature, the researchers revealed that the site contained the world’s earliest direct evidence of fire-making by Neanderthals.
Barnham was first recognized as a Paleolithic human site in the early 1900s after ancient stone tools were discovered. But recent excavations uncovered evidence of ancient human groups occupying the area more than 415,000 years ago. In one corner of the site, archaeologists found a concentration of heat-shattered hand axes as well as a zone of reddened clay. Through a series of scientific analyses, the researchers discovered that the reddened clay had been subjected to repeated, localized burning, which suggested the area may have been an ancient hearth.
The key discovery of a fire starter came when flecks of iron pyrite were found. Pyrite, also known as fool’s gold, is a naturally occurring mineral that can produce sparks when struck against flint. (While it is commonly believed that striking two pieces of flint together can create a spark, in fact that spark is too cool to produce a flame.) A metal such as pyrite is needed. Pyrite is rare in the Barnham area, suggesting that pyrite was brought to the site, most likely to build a fire.
While this was an important discovery, questions remain about the nature of early fire use: When did fire use become a regular part of the human behavioral repertoire? Was it ubiquitous or was usage scattered in a few groups? Were Neanderthals the first to discover it? Did they share it with Homo Sapiens? There are more questions than answers, but it makes you think more about the history of fire, something that we take for granted.
