Kennewick Man and Ancient One are the names generally given to the skeletal remains of a prehistoric Paleoamerican man found on a bank of the Columbia River in Kennewick, Washington, on July 28, 1996. It is one of the most complete ancient skeletons ever found. Radiocarbon tests on bone have shown it to date from 8,900 to 9,000 calibrated years before present, but it was not until 2013 that ancient DNA analysis techniques had improved enough to shed light on the remains.
