Excavations in the Channel Islands off the coast of California have revealed new evidence supporting the theory that the first inhabitants of North America arrived on the continent by sea, not on foot as previously thought.
Human remains and settlements dating back 13,000 years, along with the bones of extinct animals, paint a picture of sophisticated maritime societies with advanced sea skills, who roamed the Pacific Ocean in their boats thousands of years ago, relying on the riches of the sea for their food and transportation.
The Channel Islands, a chain of eight islands in the Pacific Ocean south of California, contain a treasure trove of archaeological finds preserved by natural conditions, most notably the remains of the "Arlington Springs Man," which were found on Santa Rosa Island in 1959 at a depth of 37 feet. Tests in 2001 confirmed that they were 13,000 years old, making them the oldest dated human remains in North America.
What made this discovery so surprising was that the site is located on an island far from the coast, meaning that its earliest inhabitants had boats and sophisticated maritime capabilities, in stark contrast to the traditional theory that the first humans crossed a land bridge from Siberia to Alaska, then headed south through an ice-free corridor in western Canada.
Now, a new documentary, released on June 30 on the Timeline YouTube channel, is once again highlighting these discoveries and mysteries that still lie beneath the islands and the surrounding waters, offering a visual narrative that reopens one of the most exciting theories in modern archaeology
Researchers today are proposing a new hypothesis known as the "Kelp Highway Hypothesis," which states that during the Ice Age, humans followed the coasts using boats, bypassing glaciers, until they reached California and its islands, supported by the presence of similar marine ecosystems extending from Japan to Mexico, which provided early humans with diverse food sources along the way.
Excavations on the islands show that mammoths roamed the area before evolving into a dwarf version called the "pygmy mammoth," which became extinct around the same time that humans appeared on the islands, suggesting that early humans encountered them and may have hunted them.
Over time, the islands became home to the ancestors of the Chumash people, who developed prosperous maritime communities, before everything changed with the arrival of the Portuguese explorer Juan Rodrigues Cabrilho in 1542. This was followed by a wave of disease and colonization that destroyed the indigenous communities and depopulated the islands, leaving behind stories like that of the "lone woman on San Nicolas Island" who lived in isolation for 18 years before being rescued in 1853.
Although some scientists still disagree about whether these islands provide conclusive evidence of maritime migration, the hypothesis is gaining increasing momentum, especially with the existence of areas that were dry during the Ice Age and are now submerged underwater, and which may hold in their seabeds additional evidence of this forgotten migration.
Scientists hope that future research in the islands and surrounding waters will reveal more secrets, considering these islands to be "a trace of a vanished world" that holds the key to a deeper understanding of ancient American history.
