New Study Reveals the Secrets of Easter Island

A new study of the stone monuments on Easter Island reveals the mysteries of the ancient people who made them.


Easter Island is one of the most mysterious places on Earth, largely due to the strange art left behind by its ancient inhabitants. This remote Chilean island in southeastern Pacific Ocean is home to 887 monumental stone statues or Moai, created by the Polynesian Rapa Nui people who used to live there. 

The questions about the statues have always abounded - why do they all look like giant heads, what do they mean, and what happened to the people who made them.  

Another mystery - how were the monoliths moved up to 11 miles from the quarry where they were carved, seemingly without using wheels or larger animals.

Over the years, scientists have proposed some explanatinos for the unknowns. 

The statues, carved from volcanic rock between 1000 and 1680 AD, seem to be honoring Rapa Nui ancestors, watching over their activities as they are turned away from the sea and towards the villages. 

Interestingly, while they are popularly identified as gigantic heads, the statues actually have bodies. Most of their torsos end up at the top of the thighs, while some are complete kneeling figures.

As far as how the statues were moved, it was possibly accomplished by utilizing special sledge devices or attaching ropes and walking them to their destinations by rocking and pulling. 

Now a new study contributes a twist to our understanding of the Rapa Nui - the people who left us these immense reminders of their time on Earth. They were commonly viewed as having a warrior culture, but an analysis of the large cylindrical stone hats, known as pukao, which top some of the statues, showed that the Rapa Nui had instead a supportive and inclusive community.

Professor Carl Lipo from Binghamton University and a team of researchers looked at 70 multi-ton hats strewn around the island. They used photography and 3D computer models to discover that the hats had many more drawings or "petroglyphs" than previously observed.  

"The diversity of the petroglyphs challenges that these were symbols of warfare between groups," said Lipo to Newsweek. In fact, the findings exhibit "quite a bit of diversity in the petroglyphs of the pukao—more so than have been traditionally noted given that we documented all the pukao surfaces."

What the drawings also reveal is that there was clearly a sense of cooperation and community that was fostered among the Rapa Nui, according to Lipo.

"These monuments represent the result of communities working together and clearly had tremendous positive value," Lipo explained. "As we've learned more about the nature of the resources on the island that are needed for community survival, we see that sharing and cooperation was a key factor ... The pukao data are another piece of the broader puzzle that we are assembling for the island."

What makes someone gay? Science is trying to get it straight.

Evolutionarily speaking, being gay is still something of an enigma

  • Heterosexual people have been less interesting to scientists than gay people, in terms of where they come from, because, evolutionarily speaking, being gay doesn't lead to a higher "higher reproductive fitness" — meaning, it doesn't lead to more babies.
  • Across cultures, gay boys tend to be more interested in spending time with their mothers.
  • We still don't really know why gay people are attracted to each other.

Suppose you forgot it was your partner's birthday, but you know that they would appreciate the smallest of gestures, say a bouquet. It's late at night and no florists are open. The cemetery on your way home has recently had a funeral, and you walk across the site and pick up a good-looking bouquet of roses from someone's grave. You then head home, and the flowers are happily received by your partner.

Would you say that you hurt anyone?
