Conventional wisdom holds that the island of Rapa Nui, also known as Easter Island, once had a large population that crashed after living beyond its means and stripping the island of resources. A new research study my colleagues and I conducted has struck another blow to this notion by using artificial intelligence to analyze satellite data about piles of rocks on this tiny island in the middle of the Pacific Ocean.
Our study looked at rock gardens, a form of subsistence farming, and determined that the island – just 15.3 miles (24.6 km) long by 7.6 miles (12.3 km) at its widest point – likely never held many more than the 3,000 or so people European explorers encountered in 1722.
