Theory Briefing

  • The Arlington Man's remains support the idea that early Americans traveled a coastal kelp highway, not just an inland ice-free corridor.
  • The kelp highway theory gains weight from a shared ecosystem — the same animals and plants running the entire coastal route.
  • This ancient 'lost world' ecosystem, now submerged, suggests a viable migration path that history has largely overlooked for 13,000 years.
