The control and use of fire stand among the most influential turning points in human prehistory, dramatically shaping the course of human evolution. Mastery over this elemental force allowed our ancestors to cook food, illuminate their shelters after dark, withstand cold climates, and craft advanced tools. Indeed, without fire, milestones such as the Industrial Revolution, the creation of early medicines, and the very foundations of creative expression may never have emerged.
However, the exact origins and initial motivations behind humankind’s relationship with fire remain a subject of continuing debate. While the traditional viewpoint has maintained that the primary use of fire among early humans was for cooking, recent findings challenge this assumption, offering a nuanced perspective on our ancestors’ survival strategies.
Challenging the "Cooking Hypothesis": New Research on Early Human Fire Usage
For decades, the prevailing scientific consensus posited that mastering fire was a gradual process—particularly significant among species like Homo erectus. The widely accepted "Cooking Hypothesis" argued that fire was chiefly employed for cooking animal flesh, which may have contributed to crucial evolutionary changes such as the shrinking of the digestive tract and the expansion of the brain in human ancestors.
However, a growing body of recent research is shifting this narrative, suggesting that the earliest application of fire by hominins was likely not for food preparation. Instead, fire may have been first leveraged as a practical tool for preserving hunted meat and protecting it from scavenging predators. Modern archaeological analyses indicate that, especially during the earliest periods, fire was lit selectively for safeguarding valuable animal carcasses rather than widespread culinary purposes.
Archaeological Evidence: Selective and Strategic Fire Use
Dr. Miki Ben-Dor, an archaeologist and leading voice in this field, notes that the origins of fire use remain one of the most contentious topics in paleoanthropology. While robust evidence shows routine domestic use of fire in cooking, heating, and lighting around 400,000 years ago, the period stretching back a million years or more is still marked by significant scholarly disagreement. In most ancient sites dating over a million years old, no consistent evidence of fire use has been uncovered. Even at sites where fire traces do exist, signs of cooked meat are notably absent. This suggests that early hominins, including Homo erectus, ignited fires for specific, high-value purposes rather than daily habits.
The sporadic and selective nature of ancient fire remnants hints at a significant motivating factor. Creating and maintaining fire was labor-intensive and would likely be justified only by pressing, energy-driven needs. According to Ben-Dor and his research colleagues, one such need could have been protecting meat from both spoilage and competition from other carnivores—a critical concern when hunting large game.
Meat Preservation Amid Scarcity of Large Prey
The research team investigated nine Paleolithic archaeological sites dating from 1.8 million to 800,000 years ago, with six sites in Africa and one in Spain featuring prominently. They supplemented this analysis by studying modern hunter-gatherer communities to understand patterns of food preservation and resource management.
Findings revealed that these archaeological sites contained abundant remains of large animals such as elephants, hippopotamuses, and rhinoceroses—species identified as vital food sources for early humans. The meat and fat stores from a single elephant, for instance, could provide nutrition for a group of 20–30 individuals spanning several weeks, making preservation paramount.
In environments where securing another large kill could not be guaranteed, safeguarding this caloric windfall from spoilage and rival scavengers became a top priority. In this context, fire was likely adopted not just for its warmth or its role in cooking but also to deter predators and facilitate the drying or smoking of meat—a form of prehistoric food storage.
Expert Perspectives and Broader Evolutionary Implications
Professor Ran Barkai, another researcher involved in this study, emphasizes, “We believe the primary motivation for using fire was to preserve large animal carcasses and protect these resources from both competitors and environmental decay. Cooking may have occurred occasionally, but it was likely a secondary benefit, not the main purpose.”
This theory aligns with a broader understanding that the gradual decline of large animal populations significantly influenced behavioral and technological innovations throughout human prehistory. As accessible megafauna became scarcer, early humans were pushed to adopt new survival strategies and tools—including the controlled use of fire.
Conclusion
This reevaluation of the role of fire in early human history adds a critical layer to our understanding of prehistoric life. Rather than being invented solely to cook food, the initial mastery of fire appears intimately tied to the urgent need to preserve high-value meat and ward off rivals. As large prey grew increasingly rare, fire became essential—not just for sustenance but for survival itself. This evolving relationship with fire exemplifies how human ingenuity and adaptability have always been shaped by environmental pressures and the challenges of competing for resources. Ongoing archaeological and interdisciplinary research will continue to deepen our insight into these formative chapters of human evolution.
