Kelp-Highway
The Kelp Highway is a theoretical migration route proposed to explain how the first humans might have arrived in the Americas. This hypothesis posits that early human settlers followed a coastal route along the Pacific Rim, utilizing the rich marine resources provided by Kelp Forests for sustenance and travel.
History and Context
The concept of the Kelp Highway was introduced by archeologists Jon Erlandson and colleagues in 2007. They suggested that the Pacific coastline, especially from Asia across the Pacific to North and South America, offered a hospitable environment for human migration due to the abundance of food resources like shellfish, fish, and sea mammals, which were supported by the kelp forests.
The theory challenges the traditional Clovis-First model, which suggests that the first humans in the Americas arrived through an ice-free corridor in what is now Canada, after the Last Glacial Maximum around 13,000 years ago. Instead, the Kelp Highway hypothesis proposes that:
- The migration could have occurred earlier, possibly as early as 16,000 years ago or even before.
- The coastal route was navigable even when much of the interior was covered by ice, due to the milder climate along the coast.
- These early migrants were likely skilled seafarers, capable of island hopping or following the coast in boats or rafts.
Supporting Evidence
Evidence supporting the Kelp Highway includes:
- Archaeological Findings: Discoveries of early human settlements along the Pacific coast, including tools and remains that predate the Clovis culture.
- Paleoenvironmental Data: Studies indicating that the coastal environment during the late Pleistocene would have been conducive to human habitation, with a stable climate and rich marine resources.
- Genetic Evidence: Genetic studies showing connections between ancient populations in Asia and Native American groups, suggesting a coastal migration route.
Implications
The Kelp Highway hypothesis has significant implications for understanding:
- The timing and routes of human migration into the Americas.
- The development of maritime technologies and seafaring skills among early humans.
- The ecological and environmental conditions that influenced human settlement patterns.
