New evidence: Easter Island civilization was not destroyed by war

Intro:

Researchers debunk a longstanding myth using elliptical Fourier analysis on ancient tools.

Hundreds of years ago, an advanced, seafaring civilization called Rapa Nui built more than 800 monuments that were so massive and ambiguous that they remain a mystery to this day. The Easter Island statues, or moai, are enormous stone figures placed along the coastline as if surveying the island’s interior lands. One of archaeology’s greatest mysteries is what happened to the Rapa Nui of Easter Island.
