 The study examined a 1.45 million-year-old hominin fossil from the Turkana region of Kenya. The fossil had several cut marks on its tibia shaft, which were confirmed by comparing them to a database of experimental cut marks. This is believed to be the first time such marks have been identified on an early Pleistocene hominin fossil. This article was authored by Brianna Pobberner, Michael Panti, and Trevor Keeville.
