Examining Prehistoric Migration Patterns in the Palauan Archipelago: A Computer Simulated Analysis of Drift Voyaging

A number of recent genetic, linguistic, and archaeological studies have attempted to ascertain the origin of settlers to the Palauan archipelago, but it remains a complex and debated issue. To provide additional insight into colonization strategies and settlement patterns, we conducted computer simulations of drift voyages to the Palauan archipelago based on historically recorded winds and currents. Drift voyages were considered here as drifting before the wind when lost, a strategy documented for Pacific Islanders. The simulations suggest that peoples drifting before the wind from the southern Philippines would have had the most success in landfall. This finding supports the current hypothesis of human colonization to the islands of Palau.
