Discovery of Ancient Stone Tools in Ukraine

Stone tools unearthed in Ukraine belong to ancient humans who used them over a million years ago, revealing the earliest known presence of hominins in Europe. The artifacts were dated using a new method involving cosmic rays and radioactive particles. The site is challenging for preservation due to its open-air exposure and acidic soil. No human fossils have been found at the site, but it is believed that Homo erectus may have been the species present.
