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 are the responsible for the decimation of the Easter Islanders and provides three reasons of support. However, the professor explains that this was a result of internal factors and refutes each of the author’s reasons.
First, the reading states that the disappearance of island’s trees results from foreign incursions. The professor refutes this point by saying that this destruction comes from stones monuments constructed by the Islanders. He explains that this pieces were built to show the status of the statues’ owners. They were used as a form of showing dominance to others. Moreover, roller tree logs were used to transport the monuments. In addition, the population started a competition to see who is more powerful, constructing more and more statues. Thus, this competition helped to increase the number of trees cut until they reached a critical point of almost total absence of wood.
Second, the article claims that another support of this claims lies on an archeological discovery of spear tips from a time close to the destruction of the Islanders. However, the professor contends that these spear tips types were built by the Islanders to attack during a warfare, not as a weapon of defense. With the decrease of the amount of fuel available, the natives reduced their fishing productivity. Likewise with this lack of food, a civil war started due to the limited resources available, so this spear tips were used in the confront.
Third, the reading avers that the appearance of a new religion provides more support for the claim. Conversely, the lecture opposes this point by stating that the new religion was not broth by invaders, but by the Islanders themselves on a different time. The professor explains that families started to die from starvation and theirs prayers were not more effective, so the Islanders adopted a new religion. He also claims that this new religion used a birdman as the principal symbol.
