On Monday, March 6 at 9 p.m., TBS will present a two-hour documentary program on the recent discovery of an ancient civilization. "Kodai Hakka-tsu Mystery (Prehistoric Excavation Mystery)" follows an international team of archaeologists, including artist and Rikkyo University professor Katsuhiko Hibino, to South America.
The northern plains of Bolivia were once considered too harsh for human habitation, but recent expeditions have discovered traces of an ancient civilization comprising almost 20,000 separate archaeological ruins, including manmade hills containing coffins and human remains.
Scientists have since concluded that this civilization could prove to be larger than any other prehistoric one in the Americas, but it will take many years to unravel the mystery.
