Archaeologists have used artificial intelligence to uncover a 2,000-year-old human drawing among Peru’s mysterious Nazca Lines.

A research team from Japan’s Yamagata University used IBM’s machine-learning programme Watson to pick out new drawings, known as geoglyphs, carved into the landscape.

Watson was fed images of already discovered carvings and tasked with picking out potential new sites for exploration from aerial photographs.

The AI then highlighted several areas to investigate, with the Yamagata team lead by Professor Masato Sakai deciding on one potential candidate in the west of the Nazca Pampa.

Further fieldwork at the area revealed one new geoglyph, a humanoid figure standing on two feet spanning around 16ft (4.9 metres) across.
