2.9-million-year-old toolkit in Kenya raises new questions

New, exciting research has revealed some of the oldest stone tools ever found — as old as 2.9 million years — to butcher hippos and pound plant material. The study unveils what could likely be the oldest examples of a significant stone-age innovation known as the Oldowan toolkit.

Led by an international group of scientists, the excavations related to the study were carried out at the site named Nyayanga, located on the Homa Peninsula in western Kenya.
