Over 300 Oldowan stone tools were discovered on the Homa Peninsula of Kenya. This was an extraordinary find for a number of reasons, so buckle up. The tools are 2.9 million years old, making them the oldest Oldowan tools ever found by about 300,000 years. They’re also some of the oldest-known stone tools that were used in the butchering of large animals (and the pounding of plants) — in this case, hippos. And that makes this the oldest known example of hominins eating meat (probably raw since it’s from before the oldest accepted evidence of fire), changing the way experts view carnivory among hominins. That’s all pretty impressive, but here’s the kicker: The only hominin remains found at the site were two molars from the genus, Paranthropus. These remains are the oldest remains of our early cousins ever found. And finding them in the same place as these tools suggests that they used them — until now, it was thought that only our direct ancestors (Homo) used Oldowan tools. In fact, this technology was once considered a marker for the beginning of human modernity. So yeah, not a bad haul by those archaeologists!
