Discoveries at Olduvai Gorge: A Glimpse into Our Past

In a groundbreaking revelation, paleoanthropologist Jackson Njau and his team have uncovered bone tools in Tanzania’s Olduvai Gorge—dating back a staggering 1.5 million years. This find not only challenges long-held beliefs about when bone tool manufacturing began but also paints a clearer picture of early human life.

From Curiosity to Pioneering Research

Njau's journey into the field of paleoanthropology began in his youth, captivated by the discoveries of the Leakey family, legends in human origins research. Growing up near Olduvai Gorge, Njau was inspired by their work and the evolution of our ancestors. Today, as a leading researcher at Indiana University Bloomington, he’s redefining our understanding of early human interactions with their environment.

Unveiling the Role of Predators in Human Evolution

Njau’s extensive research has highlighted the dangers early humans faced from predators, evidenced by his discovery of crocodilian bite marks on ancient bones. His findings suggest that these encounters were pivotal in shaping early human cognition as they learned to navigate the perils of a wild environment.
