Native american dating pacific northwest coast
The peopling of the Americas has been examined on the continental level with the aid of SNP arrays, next generation sequencing, and advancements in ancient DNA, all of which have helped elucidate evolutionary histories.Regional paleogenomic studies, however, have received less attention and may reveal a more nuanced demographic history.Cultural collections at the Burke document human heritage from around the world, including more than 1 million archaeological and ethnological objects and associated archival records.Details about specific collections are listed below, and information about collections-related services, including curation, repatriation and loan and access requests can be found on our Services and Policies page.New data is added regularly, including non-diagnostic photos for inventory.In order to protect archaeological sites, no specific locations are available.Despite regional shifts in mt DNA haplogroups, we conclude from individuals sampled through time that people of the northern Northwest Coast belong to an early genetic lineage that may stem from a late Pleistocene coastal migration into the Americas.–3).Genetic clues for the peopling of the Northwest Coast, however, may be obscured by later demographic events in the region.
Some of these collections are stored at the Burke only temporarily while others have been deposited for long-term care.Here, we report the low-coverage genome sequence of an ancient individual known as “Shuká áa” (“Man Ahead of Us”) recovered from the On Your Knees Cave (OYKC) in southeastern Alaska (archaeological site 49-PET-408).The human remains date to ∼10,300 calendar (cal) y B. We also analyze low-coverage genomes of three more recent individuals from the nearby coast of British Columbia dating from ∼6,075 to 1,750 cal y B. From the resulting time series of genetic data, we show that the Pacific Northwest Coast exhibits genetic continuity for at least the past 10,300 cal y B. We also infer that population structure existed in the late Pleistocene of North America with Shuká áa on a different ancestral line compared with other North American individuals from the late Pleistocene or early Holocene (i.e., Anzick-1 and Kennewick Man).Northwest Coast Carved sheep horn ladle finely carved with geometric lines, totemic animal, human, and avian forms.The Haida are indigenous North American Indian peoples residing in the Pacific Northwest Coast (Northern British Columbia and Southeast Alaska).
