The Polynesian settlers of Easter Island may have transported their gigantic statues by slowly rocking them from side to side to make them 'walk'. Nearly 1,000 statues litter the island, with the largest weighing about 74 tonnes and standing more than 10 metres tall. Some archaeologists propose that the statues, or moai, were transported from the quarry in a horizontal position on top of logs. However, Carl Lipo at California State University, Long Beach, and his team say that evidence points instead to an upright mode of transportation.
