The island presence was not just consistent with coastal migration — it was most economically explained by it.

Collagen, AMS, And The Science Behind The Revision

The technical breakthrough that made the revised dating possible — AMS radiocarbon dating combined with improved bone-protein chemistry — deserves a more detailed explanation than the overview provided earlier, because the method’s logic is the foundation of the entire revised age claim.

The problem of dating very ancient bone is a problem of separating what is original from what is contamination.

Over thousands of years, bone in the burial environment accumulates material from its surroundings.
