Easter Island statues, historically often called moai on the distant island of Rapa Nui within the South Pacific, are a number of the most spectacular artifacts of historical Polynesian civilization. How the statues had been transported has lengthy remained a conundrum, as a result of they’ll weigh as much as a number of tons but are scattered all through the island. Numerous theories have been proposed, together with that they had been dragged on wood sleds or rolled alongside the bottom, however no supportive proof has backed these claims.
In 2012, a US analysis workforce succeeded in propping up a 4.35-ton reproduction of a moai statue and making it “stroll.” The method, by which two groups utilizing ropes tugged the statue in reverse instructions to teeter it ahead whereas a 3rd workforce ensured it wouldn’t topple over, challenged the traditional theories that moai had been moved in a horizontal place.
The query then is how a lot effort it could have taken to maneuver a lot bigger moai. “As soon as the moai are in movement, it is under no circumstances troublesome,” defined Carl Lipo, an anthropologist at Binghamton College.
Lipo and his workforce systematically surveyed 962 moai statues on Easter Island, focusing totally on 62 discovered alongside historical roads. They lately revealed a paper offering sturdy proof that moai had been transported in an upright place.
The workforce additionally succeeded in transferring a precise reproduction of roadside moai 100 meters in 40 minutes with solely 18 folks, a much more environment friendly end result than these of earlier experiments.
Researchers reveal how the Rapa Nui folks could have “walked” moai.

The research found that moai statues positioned alongside Rapa Nui’s roads have frequent traits. The broad D-shaped base and ahead leaning design of the statues optimized the moai for “strolling,” at the same time as they elevated in measurement. The truth is, moai deserted by the facet of the highway had been discovered to have imbalanced facilities of gravity and present indicators of toppling over throughout transport.
This speculation can be supported by the traditional roads themselves, that are roughly 4.5 meters broad and have barely concave cross-sections. Researchers imagine these had been supreme circumstances to help in stabilizing the moai as they had been walked.
A statistical evaluation of the distribution of moai confirmed 51.6 p.c had been concentrated inside 2 km of the quarry the place they originated, demonstrating an exponential decay sample related to mechanical failure reasonably than deliberate ceremonial placement. It’s doubtless these statues had been broken or fell over throughout transport and left the place they lay.
