Description
Irina Velsko and co-authors test whether dental calculus can trace past human moves across Oceania. Calculus is hardened plaque that traps mouth microbe DNA for ages. Samples came from 102 people across ten Pacific islands and one Southeast Asian island. The span covers about three thousand years of island settlement.
Microbe DNA kept far better in calculus than human DNA in bone. Mouth mixes in the region stood apart from those in Europe, Africa, and Asia. Time and place shaped the mixes only weakly inside the region. Family trees of single bacterial species did track geography, though. The authors say calculus can aid migration studies beside genome work.
