Researchers have spent years grappling with the uncertain details of archaic humans’ first entry into Europe, but stone tools created about 1.4 million years ago may offer important insight.
The tools were discovered at the Korolevo archaeological site near Ukraine’s border with Romania, and have now considered the oldest known artifacts in Europe made by ancient humans. A team of archaeologists recently dated the tools and published their findings in Nature, delivering progress on critical questions about ancient human migration.
