The statues on Easter Island are among the most mysterious objects made by humans.

We still don't know how they were moved, why they were placed at particular sites around the island, and why they were made in the first place.

Now, researchers think they have at least some answers,

because a new analysis finds that the statues are located near sources of fresh water.

The study appears in the journal, Plus One.

It's believed that the residents of Rappanui, the indigenous name for Easter Island,

began constructing these carvings in the 13th century.

The statues, called Moai, which sit upon stone platforms called Ahu, are the very definition of

monumental, most way between 20 and 30 tons, and of the thousand on the island, about

400 have been moved from the quarry where they originated and placed on Ahu located elsewhere.

But those Ahu locations aren't necessarily everywhere. They're in some places and not in others.

And the questions that we started to ask ourselves was, why do we find these Ahu and Malai

some places on the landscape, but not others?

He says that most of these sculptures are found along the coast, but some are inland, and they're not necessarily in obvious places.

For example, we don't find Aahu and statues located on the tops of hills, places that we might expect to find them if these things were symbolic or representing
