Scientists of the Queensland university in Australia have disproved a hypothesis according to which the ancient civilization of rapanuyets on Easter Island has disappeared as a result of wars and resource depletion. According to scientists, tribes, despite eagerness to fight, closely cooperated with each other that has provided existence of their culture up to colonization by Europeans. It is reported in the press release on Phys.org. The first settlers from East Polynesia have arrived to Easter Island about 900 years ago. For several centuries the indigenous people has grown to more than ten thousand people. Between 1250 and 1500 natives have erected moa — statues in the form of the huge human heads located on the trunks truncated to a belt. Was considered that the culture of rapanuyets has disappeared because of wars and ecological disaster. However, according to authors of new work, the civilization of Easter Island had the complex social and political organization and has disappeared only because of colonization by Europeans in the 18th century. Scientists have carried out the chemical analysis of several tens ancient artifacts found during excavation on slopes of an extinct volcano of Rano-Raraku where stone quarries settled down. Among stone tools there were hammers and cut, the currents made of a maye — local basalt breeds of special type. Researchers also reconstructed tools by fragments to understand how they were applied. It has allowed to define how communications between the masters creating tools and sculptors were carried out. It has turned out that material for the majority of instruments of labor was delivered from one complex of stone quarries. According to Dale Simpson (Dale Simpson), one of authors of a research, it means that those tribes which used the same stone pit had to cooperate closely with each other, but not be at war. However there is a probability that one groups of the population of the island could force others to collaboration. It is more than important news in Film of Day Telegram-channel. Subscribe!
