Fragments of the left side of the skull of a human relative have been discovered in Spain, revealing the face of the oldest human ancestor ever discovered in Western Europe.

The prehistoric facial bones were found buried in 50 feet of mud and silt, and are believed to be 1.1 to 1.4 million years old, researchers said.

The facial bones of an adult nicknamed "Pink," unearthed in Spain, rewrite humankind's early history in Europe.
