Story

The narrative of this ancient life

The Kennewick Man, one of the most significant archaeological finds in North America, has greatly contributed to our understanding of Paleo-Indian culture in the Pacific Northwest. Discovered in 1996 near the Columbia River in Kennewick, Washington, this ancient skeleton is dated to be around 8,500 to 9,000 years old, placing it within the early Holocene epoch, a period critical to understanding the migration and lifestyle of early human inhabitants in North America.

Physical Characteristics and Analysis

Kennewick Man's skeleton is astonishingly well-preserved and nearly complete, providing a rare opportunity for extensive study. Standing approximately 5 feet 7 inches tall with a weight estimated at 160 pounds, his robust and athletic build suggests a highly active lifestyle, consistent with the hunter-gatherer lifestyle of Paleo-Indians. The skull, with its distinct morphology, ignited debates regarding the ancestry and migratory patterns of early inhabitants. Initial assessments suggested similarities with East Asian and Polynesian skeletal features, rather than direct lineage with contemporary Native American tribes.

Tools and Technology

The Paleo-Indians, including those contemporaneous with Kennewick Man, are known for their sophisticated tool-making skills. They utilized materials such as obsidian and chert to create finely crafted projectile points, scrapers, and knives. These tools were critical for hunting large game, fishing, and processing plant materials. The presence of a stone spearhead embedded in Kennewick Man's hip underscores the prevalence of hunting and potential intergroup conflicts or accidents in his life.

Subsistence and Lifestyle

Kennewick Man lived during a time when the environment of the Pacific Northwest consisted of diverse ecosystems, including rivers, valleys, and forests rich with resources. The people of this era adapted to these landscapes by developing a subsistence strategy that included hunting megafauna like bison and deer, fishing for salmon, and gathering plant foods. The seasonal availability of resources likely influenced migratory patterns and the establishment of temporary encampments.

Cultural and Ritual Aspects

While direct evidence of cultural practices specific to Kennewick Man is sparse, research into contemporaneous sites reveals rich spiritual and communal aspects of Paleo-Indian life. Burial practices, although varied, often included the placement of grave goods, reflecting belief systems and social structures. The careful and respectful treatment of the dead suggests a complex spiritual life, though specific details about Kennewick Man's society remain elusive.

Archaeological and Cultural Impact

The discovery of Kennewick Man prompted significant legal and ethical debates, particularly regarding the right of indigenous tribes to claim ancestral remains under the Native American Graves Protection and Repatriation Act (NAGPRA). In 2017, after years of legal battles, Kennewick Man's remains were reburied by the local Native American tribes, including the Confederated Tribes of the Umatilla Indian Reservation, honoring both scientific interest and cultural heritage.

Conclusion

Kennewick Man is a crucial piece in the puzzle of human migration and adaptation in prehistoric North America. His existence offers insight into the life of Paleo-Indians—an era marked by adaptation, resilience, and profound environmental interaction. Despite the controversies surrounding his discovery, Kennewick Man remains an invaluable artifact reflecting the deep and complex history of human habitation in the Americas, meriting ongoing study and dialogue between scientists and indigenous communities.

The ancestry and affiliations of Kennewick Man

Abstract

Kennewick Man, referred to as the Ancient One by Native Americans, is a male human skeleton discovered in Washington state (USA) in 1996 and initially radiocarbon dated to 8,340-9,200 calibrated years before present (BP). His population affinities have been the subject of scientific debate and legal controversy. Based on an initial study of cranial morphology it was asserted that Kennewick Man was neither Native American nor closely related to the claimant Plateau tribes of the Pacific Northwest, who claimed ancestral relationship and requested repatriation under the Native American Graves Protection and Repatriation Act (NAGPRA). The morphological analysis was important to judicial decisions that Kennewick Man was not Native American and that therefore NAGPRA did not apply. Instead of repatriation, additional studies of the remains were permitted. Subsequent craniometric analysis affirmed Kennewick Man to be more closely related to circumpacific groups such as the Ainu and Polynesians than he is to modern Native Americans. In order to resolve Kennewick Man's ancestry and affiliations, we have sequenced his genome to ∼1× coverage and compared it to worldwide genomic data including for the Ainu and Polynesians. We find that Kennewick Man is closer to modern Native Americans than to any other population worldwide. Among the Native American groups for whom genome-wide data are available for comparison, several seem to be descended from a population closely related to that of Kennewick Man, including the Confederated Tribes of the Colville Reservation (Colville), one of the five tribes claiming Kennewick Man. We revisit the cranial analyses and find that, as opposed to genome-wide comparisons, it is not possible on that basis to affiliate Kennewick Man to specific contemporary groups. We therefore conclude based on genetic comparisons that Kennewick Man shows continuity with Native North Americans over at least the last eight millennia.
