Using a form of artificial intelligence, researchers have discovered four new Nazca geoglyphs in Peru, according to a new study recently published in the Journal of Archaeological Science. The Nazca lines are UNESCO-protected geoglyphs dating from between 100 BCE and 300 CE that depict humans, camelids, birds, orcas, felines, and snakes. There are a range of theories surrounding their purpose, including that the Nazca geoglyphs depict deities, are a form of irrigation, or are a calendar with astrological alignments, though it remains unclear.
