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.
Tracking the Genetic Clades
By sequencing the mitochondrial DNA of ancient and modern Kiore, researchers have identified three distinct genetic groups, or "clades," that track the migration routes through the Pacific:
Clade I: Found primarily in South-East Asia and the Philippines.
Clade II: Located in the islands of Near Oceania (New Guinea and the Solomons).
Clade III: The "Remote Oceania" group found in the heart of the Pacific Triangle, including Hawaii, Rapa Nui, and Aotearoa.
By tracking where these groups overlap, we can see exactly where our ancestors stopped, how long they stayed, and which direction they headed next. The Kiore DNA confirms a complex, multi-directional journey that matches the "Slow Boat" model we discussed in previous posts.
A Deliberate Design
The presence of the Kiore across the Pacific proves that our arrival in Aotearoa was not a series of accidents or "drift" voyages. Our ancestors were explorers who travelled with an entire ecosystem in their waka—including plants like the kūmara, and animals like the kurī (dog) and the kiore.
This biological evidence validates our oral traditions: we were a people who prepared for the future. We didn't just stumble upon new lands; we brought the seeds of our old homes with us to ensure the mauri of our people would flourish in the new. The Kiore is a tiny witness to a massive achievement of planning, navigation, and foresight.
