List Two new mtDNA sequences from ancient Beringian remains have appeared on the GenBank database.

Ian www.ianlogan.co.uk ------------------------ Abstract Pleistocene residential sites with multiple contemporaneous human burials are extremely rare in the Americas. We report mitochondrial genomic variation in the first multiple mitochondrial genomes from a single prehistoric population: two infant burials (USR1 and USR2) from a common interment at the Upward Sun River Site in central Alaska dating to ∼11,500 cal B.P. Using a targeted capture method and next-generation sequencing, we determined that the USR1 infant possessed variants that define mitochondrial lineage C1b, whereas the USR2 genome falls at the root of lineage B2, allowing us to refine younger coalescence age estimates for these two clades. C1b and B2 are rare to absent in modern populations of northern North America. Documentation of these lineages at this location in the Late Pleistocene provides evidence for the extent of mitochondrial diversity in early Beringian populations, which supports the expectations of the Beringian Standstill Model. --------------------- KT891989(Beringia-ancient) Tackney Haplogroup C1b 08-NOV-2015 A73G A249- A263G A290- A291- T489C A493G C522- A523- A750G A1438G A2706G C3107N T3552A A4715G A4769G C7028T C7196A G8584A A8701G A8860G T9540C A9545G A10398G C10400T T10873C G11719A G11914A C12705T A13263G T14318C C14766T T14783C G15043A G15301A A15326G A15487T C16223T C16292T T16298C T16325C C16327T KT891990(Beringia-ancient) Tackney Haplogroup B2 08-NOV-2015 A73G A263G G499A A750G A827G A1438G A2706G C3107N A4769G G4820A T4977C C6473T C7028T C8281- C8282- C8283- C8284- C8285- T8286- C8287- T8288- A8289- A8860G T9950C C11177T G11719A G13590A C14766T A15326G C15535T A16182- A16183- T16189C 16193.1C 16193.2C T16217C T16519C
