"Early Americans Possibly Used Sea Ice 'Highway' for Arrival"

Researchers suggest that during the last ice age, the first humans to reach the Americas may have traveled along a sea ice "highway" in Beringia, providing another piece to the puzzle of how humans crossed into North America. Climate data and ocean modeling indicate that sea ice may have been used as a platform for migration, potentially aiding the journey from Asia to North America. This finding challenges previous theories and highlights the adaptability of ancient migrants to rapidly changing conditions.

North America's First Migrants: Tracing the Sea Ice Highway

New research challenges traditional theories of how and when humans first arrived in North America, suggesting that early Americans may have traveled along a "sea ice highway" along the Pacific Coast as early as 24,000 years ago. Paleoclimate reconstructions of the Pacific Northwest indicate that sea ice may have provided a means for people to move farther south. This theory complements the idea of a "kelp highway" and highlights the adaptability of early humans. While proving the use of sea ice as a migration path is difficult due to underwater archaeological sites, it offers a new framework for understanding human migration in North America.

Ancient Arrival: North America's First People Traveled via Sea Ice Highway

New research presented at the American Geophysical Union Annual Meeting suggests that North America's first people may have arrived as early as 24,000 years ago by traveling along a "sea ice highway" along the Pacific coastline. Paleoclimate reconstructions of the Pacific Northwest indicate that sea ice may have provided a platform for early Americans to move farther south, aided by lower sea levels and glacial winds. This theory challenges the traditional belief that people walked through an ice-free corridor 13,000 years ago and provides a new framework for understanding human migration to North America.
