Oldest stone tools in Europe hint at ancient humans’ route there

Stone tools found in western Ukraine date to roughly 1.4 million years ago, making them the oldest known artefacts in Europe made by ancient humans. The findings support the theory that our early relatives — probably of the versatile species Homo erectus — first entered Europe from the east and spread west. The type of tools, and the location where they were found, hint that the first Europeans might have moved westwards along the valleys of the Danube River.
