Intriguing New Theory Might Explain the Fate of Easter Island's Civilization

Standing up to 33 feet high and weighing 81 tons, the huge moai statues of Easter Island (Rapa Nui) are the most recognizable artifacts of a thriving civilization that peaked at the middle of the last millennium. For hundreds of years, Polynesian peoples lived on the small island 2300 miles west of Chile and developed a complex culture. By the 1700s, when Europeans first arrived, much of the society was decimated.

For years, scientists thought they knew why—but fresh archaeological evidence has provided an alternative theory.

The Journal of Pacific Archaeology published a paper [PDF] this week contradicting the commonly held belief that, in the 1600s, Rapa Nui's inhabitants descended into a Lord of the Flies–like era of infighting and violence as a result of dwindling resources. According to new research, the island’s population may not have devolved into barbarism. Instead, they were collaborating on toolmaking.

University of Queensland archaeologist Dale Simpson, Jr. theorized that the raw materials used in the carving tools would reveal clues about the dynamics of the community. He and his colleagues collected 17 tools found near the moai, including axe-like toki. Using a mass spectrometer to analyze the chemical composition of the tools and samples from stone quarries on the island, Simpson and his colleagues found that most of the toki came from a single quarry.

Simpson believes this is evidence that Rapa Nui's people had not fallen into violent conflict, but were instead sharing resources—or at least allowing one another access to a favorite quarry for tool production. If the islanders were split into factions, it’s unlikely that whoever was controlling the quarry would permit rivals to make use of it.

If accurate, it would join other recent theories that are drawing a revised picture of Rapa Nui's civilization. Explorers once described a surplus of spear-like objects presumably used for combat, but modern researchers examining the tools (called mata’a) in 2015 found that their surfaces were too blunt to pierce skin and were probably used for tilling soil.

While Simpson's take on the newly discovered carving tools is an intriguing theory, researchers aren't ready to rewrite history just yet. Other scholars, including study co-author Jo Anne Van Tilburg, point out that raw materials for the tools could have been seized by force or some form of coercion.

More research will be needed to see if Simpson’s new theory holds up. If it does, it would present a new wrinkle in the storied history of Rapa Nui.

Did the Northern Lights Play a Role in the Sinking of the Titanic? A New Paper Says It’s Possible

The sinking of the RMS Titanic on April 15, 1912, is the most famous maritime disaster in history. The story has been retold countless times, but experts are still uncovering new details about what happened that night more than a century later. The latest development in our understanding of the event has to do with the northern lights. As Smithsonian reports, the same solar storm that produced an aurora over the North Atlantic waters where the Titanic sank may have caused equipment malfunctions that led to its demise.

Independent Titanic researcher Mila Zinkova outlines the new theory in a study published in the journal Weather. Survivors and eyewitnesses from the night of the Titanic's sinking reported seeing the aurora borealis light up the dark sky. James Bisset, second officer of the ship that responded to the Titanic's distress calls, the RMS Carpathia, wrote in his log: "There was no moon, but the aurora borealis glimmered like moonbeams shooting up from the northern horizon."

Zinkova argues that while the lights themselves didn't lead the Titanic on a crash course with the iceberg, a solar storm that night might have. The northern lights are the product of solar particles colliding and reacting with gas molecules in Earth's atmosphere. A vivid aurora is the result of a solar storm expelling energy from the sun's surface. In addition to causing colorful lights to appear in the sky, solar storms can also interfere with magnetic equipment on Earth.

Compasses are susceptible to electromagnetic pulses from the sun. Zinkova writes that the storm would have only had to shift the ship's compass by 0.5 degrees to guide it off a safe course and toward the iceberg. Radio signals that night may have also been affected by solar activity. The ship La Provence never received the Titanic's distress call, despite its proximity. The nearby SS Mount Temple picked it up, but their response to the Titanic went unheard. Amateur radio enthusiasts were initially blamed for jamming the airwaves used by professional ships that night, but the study posits that electromagnetic waves may have played a larger role in the interference.

If a solar storm did hinder the ship's equipment that night, it was only one condition that led to the Titanic's sinking. A cocktail of factors—including the state of the sea, the design of the ship, and the warnings that were ignored—ultimately sealed the vessel's fate.
