Episode notes
Revised Arrival Date Of Hawaiians
- Polynesians reached Hawaii around AD 1000 after a rapid eastward expansion from Tonga-Samoa.
- Improved radiocarbon methods revised earlier older arrival dates downward to ~AD 1000.
Seaworthy Double-Hulled Canoes
- By the expansion period Polynesians built double-hulled voyaging canoes capable of month-long voyages.
- These vessels carried dozens of people plus supplies and planting stock for colonization.
Pristine Islands And Rapid Ecological Impact
- Hawaii was ecologically pristine with no land mammals and many endemic birds, including large flightless species.
- Human arrival quickly drove extinctions and ecosystem collapse in lowlands.
