Summary Points
- Early humans, specifically Homo erectus, controlled fire inside Wonderwerk Cave from about 1.07 to 1.79 million years ago, pushing back the timeline much earlier than previously believed.
- Researchers used a new, non-invasive luminescence technique alongside chemical analyses to confidently detect ancient burned bones deep within the cave, despite the passage of millions of years.
- The fire was likely not accidental,it was probably made possible by humans recognizing and maintaining natural fires, such as those from lightning or wildfires, rather than starting fires themselves.
- This discovery highlights that early humans engaged actively with fire—using it for warmth, safety, and light—demonstrating a sophisticated understanding of fire’s importance long before they learned to create it deliberately.
Fire Use Dates Back Nearly Two Million Years
New research reveals that early humans started using fire between 1.07 and 1.79 million years ago. This evidence pushes back the earliest known use of fire by nearly two million years. Previously, scientists believed humans first controlled fire around one million years ago. The discovery was made through tiny fossil bones found deep inside Wonderwerk Cave in South Africa. The bones showed clear signs of heat damage, indicating that fire was present far earlier than once thought. This breakthrough helps us better understand when humans began to harness fire’s practical benefits.
How Did Early Humans Use Fire?
The findings suggest early humans didn’t create fire from scratch at that time. Instead, they likely recognized natural fires caused by lightning or wildfires. They then carried burning materials into the cave, maintaining the flames. Maintaining fire took skill and awareness. It provided warmth, safety, and light in the dark. Interestingly, the evidence shows that early humans kept fire inside the cave, far from natural ignition sources. This behavior indicates they valued fire and understood its importance in their daily lives.
The Significance for Human Progress
This discovery reveals that early humans actively engaged with fire much earlier in history. They didn’t just observe natural fires—they recognized and controlled them. This ability likely helped humans adapt to various environments, survive colder climates, and defend against predators. The research also demonstrates technological progress. Using new scientific techniques, researchers can now detect ancient fire more accurately. In doing so, they open a window into how humans evolved and how critical fire became to our journey as a species.
