The traditional Polynesians who settled the island of Rapa Nui – previously generally known as Easter Island – could have labored out an ingenious method to make their iconic moai statues ‘stroll’.
It is not simply native legend; it is physics, say anthropologists Carl Lipo and Terry Hunt, and it could possibly be but one more reason the self-destructive ‘ecocide’ idea of Rapa Nui is incorrect.
In a brand new paper, Lipo and Hunt argue the traditional individuals of this distant island hadn’t recklessly reduce down their bushes to move moai statues on picket rollers, as the favored story goes; they did not have to – that they had a neater possibility.

For hundreds of years, the Indigenous individuals of Rapa Nui have shared a rhythmic tune that tells the story of their ancestors, who knew learn how to make their statues stroll.
Western students have lengthy dismissed these oral narratives as metaphorical or mythological, however in 2012, Lipo (from Birmingham College) and Hunt (from the College of Arizona) collaborated with the primary Rapanui governor, Sergio Rapu Haoa, to revive the contentious vertical transport idea and provides it new legs.
In accordance with their 3D fashions and experiments, the difficult half is getting the massive rock a-rocking, however as soon as it is oscillating backward and forward, the statue can waddle ahead with little effort and a few steerage from rope handlers.
Researchers know as a result of they’ve tried it. In 2012, 18 individuals efficiently ‘walked’ a 4.35-ton moai duplicate 100 meters (328 toes). It took them simply 40 minutes.
“The moai walked – the proof is carved in stone, validated by way of experiments, and celebrated in up to date Rapa Nui tradition,” write Lipo and Hunt in a brand new paper that responds to their critics.
“The query is why some students, regardless of claiming allegiance to scientific ideas, nonetheless refuse to just accept this mannequin for the transportation of moai.”

Proof is now stronger than ever that the mysterious inhabitants collapse of Rapa Nui by no means truly occurred. Latest genetic and archaeological analysis means that the native individuals of the island are incorrectly blamed for their very own demise, when their inhabitants collapse was extra probably attributable to slave raids and overseas illness.
Of their new paper, Lipo and Hunt tackle every of their critics, together with writer Jared Diamond, who popularized the ecocide narrative of Rapa Nui in his 2005 guide Collapse: How Societies Select to Fail or Succeed.
Diamond rejected Lipo and Hunt’s idea in 2012 as an “implausible recipe for catastrophe”, which might too simply danger breaking moai statues on unpaved hilly terrain.
However moai statues did break, typically in comparable methods. Some are deserted alongside historic roads that will have been considerably shaped by the march of the statues themselves.
“[Diamond’s] argument ignores each the physics of managed pendulum movement and the archaeological proof,” write Lipo and Hunt. “His adherence to horizontal transport [on wooden rollers] probably displays a dedication to his ‘collapse’ narrative quite than empirical analysis.”
The long-lasting moai statues on Rapa Nui will not be symbols of environmental self-destruction, argue Lipo and Hunt, however of resourceful ingenuity.
The research was revealed within the Journal of Archaeological Science.
