anzick-1's mtdna, nuclear dna, and y-chromosome analysis revealed a close genetic affinity to modern native americans and provided evidence of gene flow from siberia into the americas nearly 13,000 years ago, earlier than thought.[4] these findings tend to support the beringia hypothesis of the peopling of the americas, and tend to refute the solutrean hypothesis which argues for pale-european migration to the new world and which had little academic support even prior to the sequencing of anzick-1's genome.[13][4] the beringia hypothesis is the mainstream model for the peopling of the americas, which posits a migration of early amerindians from siberia across a land bridge that spanned the bering strait.[14] this hypothesis is supported by genetic and archaeological evidence that places the migration no earlier than 32,000 years ago.[15] ancient native americans could have entered the new world across the beringian land bridge, and passing south from alaska through an ice-free corridor in canada. another concept is that they used boats to sail along the coast of siberia, the beringia land bridge, and the pacific coast of north america.[15] archeological evidence at the former area of the land bridge or a coastal path has been lost because of the rise in sea levels. the anzick-1 paleogenetic analysis lends support to the beringia hypothesis theory, showing that humans had arrived in montana by nearly 13,000 years ago.[3]
