Artificial intelligence just solved one of the biggest mysteries in archaeology

Massive Discovery: In six months, AI from a collaboration between Yamagata University and IBM doubled the known number of Nazca lines, discovering 303 new geoglyphs across Peru’s coastal desert.
Historical Scope: The Nazca lines were created between 200 B.C. and A.D. 650, featuring animals, plants, and geometric patterns spread across hundreds of meters.
Technological Breakthrough: For the first time, AI algorithms trained on aerial images were used to detect these designs that were previously invisible due to the desert’s scale and traditional survey limitations.
New Insights into Purpose: The newfound geoglyphs likely served ceremonial, astronomical, or territorial purposes, with many forming ceremonial paths used in sacred processions.
Expanding AI Utilization: AI is increasingly used in archaeology to uncover ancient structures globally, from burial mounds to shipwrecks, significantly speeding up the research process.
Human Oversight Required: While AI tools greatly enhance discovery efficiency, archaeologists stress the necessity of verifying all discoveries in person due to the current limitations of algorithmic precision.
Preservation and Reconstruction: As AI technology advances, there is an increased opportunity to protect ancient sites and reconstruct lost worlds with greater accuracy, providing deeper insights into ancient cultures like the Nazca.
