In southwestern Kenya, archaeologists have made a fascinating discovery: stone tools that could be up to 3 million years old. Found near fossils of Paranthropus, a relative of modern humans, these tools might be the oldest of their kind ever uncovered.
Located at the Nyayanga archaeological site near Lake Victoria, these tools were excavated over eight years and number more than 300, primarily made from quartz and rhyolite. This site challenges our understanding of early human technology, as these tools are classified as Oldowan, previously thought to be linked only to the genus Homo.
This discovery has important implications. It suggests that even non-Homo species like Paranthropus might have used tools, which was a long-held misconception among scientists. The fossils and tools found alongside one another indicate that Paranthropus, which lived around 2.9 million years ago, could have had the ability to use tools in novel ways.
“Paranthropus has been viewed as a tool-less hominin, but our findings suggest otherwise,” noted Emma Finestone, a paleoanthropologist from the Cleveland Museum of Natural History involved in the excavation.
The site also revealed animal remains, including butchered hippopotamus bones. This adds complexity to our understanding as it was previously believed that early hominins lacked the tools or skills to process large animals for food. Whether Paranthropus hunted or scavenged these animals remains unclear, but the evidence suggests they were capable of processing significant meat sources.
“This marks the first evidence of Paranthropus potentially butchering large animals,” stated Thomas Plummer, a professor of anthropology at Queens College and the lead author of the study published in Science. “Such a finding could reshape how we perceive early human-animal interactions.”
The Oldowan tools from Nyayanga are a critical part of early human technology. While they may appear rudimentary, they represent a significant advancement in tool-making that played a vital role in the evolution of our ancestors. Used for cutting and scraping, these tools have influenced hominin behavior for over a million years across Africa and beyond.
Previously, the oldest known Oldowan tools were found in Ethiopia, dating back about 2.6 million years. The Nyayanga tools push this timeline even further, presenting a new perspective on human history.
Recent studies suggest that the ability to use tools may have been more widespread among early hominins than we once believed. With more excavations taking place in Africa, we may continue to uncover surprising insights regarding our ancestors and their capabilities.
This discovery is reshaping our understanding of early human history and the role of tool use in shaping our species’ evolution.
