New findings from Wonderwerk Cave in South Africa reveal that early human ancestors transported and maintained fire inside the cave between 1.07 and 1.79 million years ago, marking some of the earliest known use of fire by hominins.
- Oldest evidence of fire use by humans found in Wonderwerk Cave
- Fire was brought deep inside the cave, beyond natural wildfire reach
- New light-based technique detects ancient burned bones
What happened
Researchers investigating Wonderwerk Cave in South Africa used advanced luminescence techniques to analyze fossilized animal bones. They discovered evidence of burning dating back as far as 1.79 million years ago, located deep inside the cave where natural wildfires could not have impacted. This strongly suggests that early humans, likely Homo erectus, were intentionally bringing fire into the cave and maintaining it.
This study extended previous discoveries from 2012 that identified fire use about 1 million years ago at the same site. By combining new light-emitting bone analysis with chemical testing, scientists were able to detect traces of burned bones with greater confidence, revealing repeated fire presence linked to early Acheulean stone tool layers in the cave.
Why it feels good
The ability to harness fire was a major milestone in human evolution, offering warmth, protection from predators, light in darkness, and the eventual ability to cook food. This discovery pushes back the known timeline of human interactions with fire and showcases the adaptability and survival skills of our distant ancestors.
Understanding when and how early humans first used fire helps illuminate the origins of cultural and technological development. These findings suggest early humans were not just passive observers but actively managed naturally occurring fires, marking the start of complex behavior that shaped humanity’s future.
What to enjoy or watch next
Future research will continue exploring Wonderwerk Cave and other ancient sites to better understand early human behavior surrounding fire. The new non-invasive bone luminescence method offers promising application to large fossil collections worldwide, potentially unveiling even older traces of fire use.
For those interested in the story of human evolution, documentaries and museum exhibits about the discovery of fire and early hominin life frequently incorporate findings from Wonderwerk Cave. These resources help visualize the dramatic advances our ancestors made and their remarkable journey toward modern humanity.
