Human remains discovery ‘rewrites’ history of Amercian colonisation | History | News

A remote chain of islands off the coast of California may hold clues to rewriting the story of America’s first inhabitants.
California’s own Channel Islands are home to 13,000-year-old human remains, ancient settlements, and archaeological evidence that suggests some of the first people to reach North America may have arrived by boat rather than using an inland route from Siberia.
If the theory is correct, it would challenge the long-held belief that early Americans crossed a land bridge between Siberia and Alaska before advancing south through an ice-free corridor in Western Canada.
Instead, researchers believe some early immigrants may have followed the Pacific coastal route known as the “kelp highway,” using boats to travel along the coastline and settle in areas including the Channel Islands.
The islands also reveal pygmy mammoth remains and remarkably preserved archaeological sites, giving scientists a rare glimpse into life during the Ice Age.
The discoveries point to a forgotten sea migration that could change the understanding of how humans first spread across the Americas, researchers say.
But not all archaeologists agree that the Channel Islands provide conclusive evidence of early coastal migration.
While there is now broad agreement that humans existed in the Americas before the Clovis culture, experts continue to debate when the first settlers arrived and whether they traveled by sea, land, or various routes.
The eight California Channel Islands are located in the Pacific Ocean off Southern California, stretching from Point Conception near Santa Barbara to waters south of Los Angeles.
A new documentary released by YouTube channel Timeline on June 30 has revived interest in discoveries and unanswered questions about the islands.
Author Frederic Caire Chiles, who holds a doctorate in history from the University of California at Santa Barbara, described the islands as “a trace of a vanished world.”
The four northern islands, San Miguel, Santa Rosa, Santa Cruz and Anacapa, were not always where they are today.
Geologists believe they were once much further south, near present-day San Diego, before tectonic movement slowly shifted them northward, rotating them about 110 degrees.
The islands have become an important focus for archaeologists; because the ancient ruins here are unusually well preserved, preserving evidence lost elsewhere due to rising seas and thousands of years of human activity.
One of the most important discoveries was that of Arlington Springs Man, whose remains were found on Santa Rosa Island and were later dated to be at least 13,000 years old.
The bones were discovered in 1959 about 10 meters below waterlogged layers of sand, mud and gravel.
Geologist and radiocarbon dating expert Dr. Thomas Stafford said tests conducted in 2001 showed that the remains were the oldest dated human skeletal remains in North America at the time.
The discovery was particularly significant because the remains were approximately the same age as the Clovis culture, once considered the oldest known population in the Americas.
But unlike the Clovis sites, Arlington Springs Man was found on an offshore island; This suggests that the first inhabitants may have already had advanced seafaring abilities.
The Clovis people were known for their distinctive fluted spear points and were traditionally believed to have entered North America through an ice-free corridor in Canada.
Discoveries in the Channel Islands raised the possibility that another population would follow the Pacific coast and reach the continent.
The existence of humans on an island thousands of years ago created a major archaeological question; because reaching the region would have required boating and seafaring skills much earlier than many researchers previously believed.
This idea is known as the “kelp highway” hypothesis.

Santa Barbara Museum of Natural History anthropology curator Dr. John Johnson said: “From Japan to Baja California, there are kelp forest ecosystems with very similar animal species.
“This ties into the whole coastal migration idea, which is an ancient coastal migration where people used watercraft and when they encountered glaciers, they went around the glaciers and moved downstream until they came to California.”
He added: “Humans appeared on this island about 13,000 years ago and over time evolved into the group we know as the Chumash.”
The ancestral homeland of the Chumash people includes the central and southern coastlines of California as well as the four northern Channel Islands.
During the Ice Age, mammoths lived on a larger landmass connecting the northern islands before eventually evolving into smaller forms known as pygmy mammoths.
The species disappeared around the time humans arrived on the islands, leading some researchers to suggest that early islanders may have encountered or hunted miniature animals.
For thousands of years, the islands were home to Chumash ancestors who developed sophisticated seafaring societies and traded shell beads with mainland communities.
The arrival of Portuguese explorer Juan Rodríguez Cabrillo in 1542 marked the first recorded European contact with California and transformed life on the islands.
“This was Europe’s furthest reflection on a world they knew nothing about,” said one historian.
Disease, colonization, and social disruption subsequently devastated Indigenous communities and contributed to the abandonment of some island settlements.
One of the most famous stories about the islands is that of the “Lone Woman of San Nicolas Island” who survived alone for nearly 18 years before being rescued in 1853.
His story later inspired the novel Island of Blue Dolphins.
Today, researchers believe that the Channel Islands still contain many undiscovered clues hidden beneath their landscape and surrounding waters.
During the Ice Age, sea levels were hundreds of meters lower; This means that the areas now flooded may have once been dry land where some of America’s first settlers lived.
