How did Easter Island's enormous stone heads get there?

The answer

The nearly 1,000 moai statues on Easter Island (Rapa Nui) were carved from volcanic tuff between 1250 and 1500 CE, with the tallest standing 10 meters high and weighing 82 tons. Experiments have shown the Rapa Nui people likely 'walked' them to their platforms by rocking them side to side using ropes, similar to moving a refrigerator. The massive deforestation required for rollers and ropes may have contributed to the island's eventual ecological collapse.
