OUR ANCIENT VOYAGE #505 - HITCHHIKERS OF THE MOANA: WHAT THE KIORE TELLS US ABOUT OUR JOURNEY

When we trace our whakapapa across Te Moana-nui-a-Kiwa, we often focus on human DNA. However, some of the most precise evidence for our journey doesn't come from human cells at all. It comes from the "passengers" our ancestors deliberately carried on their waka. Specifically, the Pacific Rat, or Kiore (Rattus exulans), has become one of the most important biological markers in modern science for mapping our ancient path.

The Voyaging Proxy

In science, we use the term "proxy" to describe something that represents something else. Because the Kiore is not a strong swimmer and cannot cross open oceans on its own, its presence on an island is proof that it was carried there by humans.

Unlike the common European rat, which "stowed away" on ships, the Kiore was an intentional part of the voyaging kit. It was a source of protein and a pet. Because the Kiore lived in such close proximity to our ancestors and shared the same waka, their DNA serves as a high-resolution map of human movement.
