Fire has been a crucial part of human life for millions of years. But when did we first start using it? Scientists have discovered that early humans were bringing fire into caves in South Africa around 1.8 million years ago. This is earlier than previously thought, and it gives us new clues about how our ancestors learned to harness fire.

The discovery was made by a team of scientists led by Dr. Liora Kolska Horwitz from the Hebrew University of Jerusalem. They used a special technique that can detect signs of burning in fossilized bones to find evidence of repeated fires deep inside the cave. Because these traces were found far beyond where natural wildfires could have reached, it suggests that early humans deliberately brought fire into the cave and kept it burning.

This new study builds on earlier work at Wonderwerk Cave, which is located in South Africa's Kalahari Desert. In 2012, researchers reported evidence of fire dating back to around 1 million years ago. But this latest discovery extends that timeline even further, showing that early humans were using fire as far back as 1.07 to 1.79 million years ago.

Fire was a game-changer for our ancestors. It provided warmth, protection from predators, light after dark, and eventually the ability to cook food. But determining when humans first started using fire has been one of archaeology's biggest mysteries. This new study provides fresh clues about how ancient human ancestors may have interacted with fire long before they learned how to produce it themselves.

Why It Matters

Understanding when and how our ancestors first used fire can help us learn more about their daily lives and how they adapted to their environments. It's also important for understanding the development of human culture and society.
