Professor Popp said: “Human and animal bone retain isotopic ratios that reflect a consumer’s diet in life.

By studying these isotope ratios, particularly in individual amino acids, we estimated the relative proportions of different food sources in each individual’s diet.” Christian-Albrechts from the University of Kiel Thomas Larsen, added: “We used three independent lines of isotopic evidence to determine what the ancient Rapa Nui people ate.

However, Rapa Nui is not a tropical paradise with fertile soils so crop productivity decreased.

The result was they drove themselves to cannibalism and ended up in effectively post-apocalyptic conditions.

“The Rapa Nui people were, not surprisingly, smart about how they used their resources,” he said. Diet of the prehistoric population of Rapa Nui (Easter Island, Chile) shows environmental adaptation and resilience.

And all the misunderstanding comes from our preconceptions about what subsistence should look like, basically European farmers thinking, ‘Well, what should a farm look like?

For years the tale of how the inhabitants of Easter Island depleted their soils and destroyed their ecosystem has been a cautionary tale for western civilisation.

There's just one problem with this as a historical warning - it seems that it never happened.

Other samples were provided by Terry Hunt at the University of Oregon and Carl Lipo professor of anthropology at Binghampton University that were collected as part of University of Hawai‘i archaeological field schools.

In Professor Brian Popp’s laboratory at the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology (SOEST) and in the Leibniz Laboratory for Radiometric Dating and Stable Isotope Research at the Christian-Albrechts University of Kiel, Germany, the team analysed the stable isotope ratios of carbon and nitrogen in archaeological soils, human and animal bone and plant remains from around 1400 AD, and modern soil and plant samples from the island.

The marine element also means that radiocarbon dates will appear older than reality, as C takes time to transition to the submarine environment.
