Easter Island
Approximately 500 years ago, the flourishing society of Easter Island suffered a steep decline in population. Many theories have surfaced explaining how this could have happened to such a thriving culture. Within this small, isolated island in the Pacific Ocean, researchers have uncovered archaeological evidence that clearly indicates one theory for the decimation of the Easter Islanders above all others: invaders.
First, the disappearance of nearly every tree on this Island points to the kind of environmental destruction that could only result from foreign incursions. Researchers discovered that this land now devoid of trees was once covered with palms. Biological evidence indicates an abundance of palm for centuries until about 500 years ago, the time when the population nearly vanished. Only invaders could have brought about that kind of destruction all at once.
Another key piece of support lies in the archeological discovery of spear tips that appeared at around the same time as the near destruction of the Islanders. These spear tips show beyond any doubt that there was conflict and warfare on the island best explained by the onslaught of invaders. In addition to these war implements, skeletons from that time have been examined and show the kind of deformation that results only from combat.
Last, the appearance of a new religion provides more support. Special dating methods used by archeologists determined that “birdman” statues surfaced at the same time as the dramatic shift in population. As history proves time and time again, when an invading force occupies a new territory, it takes with it its customs, culture, and religion. The abandonment of the old religious order for the new “birdman” religion as evidenced by these statues must be understood as the outcome of invasion.
The article states that invaders caused the decimation of the Easter Islands and provides three reasons to support. However, the professor refutes each explanation by saying that the claim made by the article is sadly wrong. He explains that internal factors cause the decimation of the Easter islands.
First, the reading claims that the disappearance of trees is an indication of how foreign incursions caused environmental destruction. However, the professor refutes the claim by explaining that many communities were present on the Islands, and each community built stone statues, which represented status. He explains that communities constructed statues as many as possible to show dominance over other communities. Statues were made from the tree logs: consequently, many trees were cut down, which showed a sense of competition. As a result, internal factors were responsible for the disappearance of trees.
Second, the article states that sphere tips were found at the same time as the population declined, showing the evidence of the presence of invaders. However, the professor states that sphere tips were made to attack fellow islanders. He explains that the resources were scarce on the island, and low trees were present on the island, resulting in less food, which gave rise to civil war for the resources. Consequently, the appearance of sphere tips is because of the civil war caused for the resources.
Third, the birdman statue appeared at the same when a dramatic shift in population took place. However, the professor refutes the claim by explaining that the new religion was not brought by the invaders but by the islanders. He explains that in a difficult time when people died due to starvation and the civil war was taking place, the islanders thought that the current religion was ineffective and therefore adopted a new religion. Hence, the islanders adopted the new religion.
