Pacific seafarers reach America 16,000 years ago?

New evidence further supports the theory that the Americas were settled by Pacific seafarers who may have arrived as early as 16,000 years ago.

These early mariners may have used the Kuroshio (Japan) Current, which flows off the east coast of Japan toward the Aleutian Islands and then southward were it merges with the California Current. The latter current flows down to the tip of Baja California where one can either proceed West toward Hawai'i or further south to the western coasts of Central and South America.

Were seafarers living here 16,000 years ago?

Site off Queen Charlottes could revolutionize our understanding of New World colonization

In a Canadian archeological project that could revolutionize understanding of when and how humans first reached the New World, federal researchers in B.C. have begun probing an underwater site off the Queen Charlotte Islands for traces of a possible prehistoric camp on the shores of an ancient lake long since submerged by the Pacific Ocean.

The landmark investigation, led by Parks Canada scientist Daryl Fedje, is seeking evidence to support a contentious new theory about the peopling of the Americas that is gradually gaining support in scholarly circles. It holds that ancient Asian seafarers, drawn on by food-rich kelp beds ringing the Pacific coasts of present-day Russia, Alaska and British Columbia, began populating this hemisphere thousands of years before the migration of Siberian big-game hunters -- who are known to have travelled across the dried up Bering Strait and down an ice-free corridor east of the Rockies as the last glaciers began retreating about 13,000 years ago.

The earlier maritime migrants are thought to have plied the coastal waters of the North Pacific in sealskin boats, moving in small groups over many generations from their traditional homelands in the Japanese islands or elsewhere along Asia's eastern seaboard.

Interest in the theory -- which is profiled in the latest edition of New Scientist magazine by Canadian science writer Heather Pringle -- has been stoked by recent DNA studies in the U.S. showing tell-tale links between a 10,000-year-old skeleton found in an Alaskan cave and genetic traits identified in modern Japanese and Tibetan populations, as well as in aboriginal groups along the west coasts of North and South America.

The rise of the "coastal migration" theory has also been spurred by a sprinkling of other ancient archeological finds throughout the Americas -- several of them, including the 14,850-year-old Chilean site of Monte Verde, too old to fit the traditional theory of an overland migration by the "first Americans" that didn't begin for another millennium or two.

Proponents of coastal migration argue that Ice Age migrants in boats might have island-hopped southward along North America's west coast as early as 16,000 years ago, taking advantage of small refuges of land that had escaped envelopment by glaciers.

The difficulty is that nearly all of the land that might contain traces of human settlement or activity -- the critical proof for archeologists -- is now under water.

Several significant finds have been made in raised caves along the B.C. coast that were not inundated by the rising Pacific in post-glacial Canada.

In 2003, Simon Fraser University scientists reported the discovery of 16,000-year-old mountain goat bones in a cave near Port Eliza on Vancouver Island, and similar finds of prehistoric bear bones pre-dating the glacial retreat have been held up as proof of a shoreline ecosystem that could have sustained large mammals, as well as human hunters.

The new Parks Canada target is at a site in the Gwaii Haanas National Park Reserve just north of Burnaby Island, near the southern end of the Queen Charlottes.

Although this "new" evidence supports archaeological arguments, many may be interested to know that genetic data has argued this for quite some time now. In American Indian mtDNA, Y Chromosome Genetic Data, and the Peopling of North America, Dr. Jones discusses how the genetic evidence pushes back the intial peopling of the Americas to around 20,000-35,000 years ago. This is far earlier than current archaeological evidence, although the new studies coming out of B.C. are helping to make the genetic and archaeological evidence correspond.
