Stone tools in Ukraine dated to 1.4 million years ago may be the earliest solid evidence of humans in Europe, a new study reveals. The makers of these tools likely weren't Homo sapiens but a close, now-extinct relation.
Scientists analyzed finds from the archaeological site of Korolevo in western Ukraine, where researchers have unearthed stone tools, such as choppers, from the Paleolithic (2.6 million to 10,500 years ago) since the site's discovery in 1974.
