Anzick-1 is the name given to the skeletal remains of Paleo-Indian male infant found in Western Montana in 1968 that date to 12,707-12,556 years BP.[1] Anzick-1 is the only human that has been discovered from the Clovis Complex, and is the first ancient Native American genome to be fully sequenced.[2]
Paleogenomic analysis of the remains revealed Siberian ancestry and a close genetic relationship to modern Native Americans.[1][2] These findings support the hypothesis that modern Native Americans are descended from Asian populations who crossed Beringia between 32,000 and 18,000 years ago, and discredits the Solutrean Hypothesis[1][2].
Anzick-1's discovery and subsequent analysis is controversial because although the researchers did not violate the Native American Graves Protection and Repatriation Act (NAGPRA), many Montana tribal members believe they should have been consulted before the analysis of the infant's skeleton and genome.[3]
Discovery
The Anzick site was accidentally discovered by a construction worker in a collapsed rock shelter near Wilsal, Montana.[4][5] The site contained hundreds of of stone projectile points, blades, and bifaces as well as two juveniles[5] Some of the artifacts were covered in red ochre.[5] The stone points were identified as part of the Clovis Complex because of their distinct shape and size.[4] Originally, the two human skeletons were both thought to contemporaneous with the Clovis Complex stone points, but later carbon dating revealed that only one of the human skeletons, Anzick-1, was from the Clovis period.[4] Anzick-1 predates the other skeleton by two millennia.[4]
Osteological Findings
Paleogenetic Findings
A team of researchers throughout the United States and Europe conducted paleogenetic research on the Anzick-1 skeletal remains. They sequenced the mitochondrial DNA (mtDNA), the full nuclear DNA, and the Y-chromosome, and compared these sequences to those of modern populations throughout the world.[1] The results of these analyses allowed the researchers to make conclusions about ancient migration patterns and the peopling of the Americas.
Mitochondrial DNA Analysis
MtDNA is DNA located in mitochondria, an organelle that is found in human cells. The mitochondria is maternally inherited and analysis of the mtDNA can provide information about maternal ancestry.[6] MtDNA genomes are classified into different haplogroups based on a shared common ancestor, and distinct haplogroups provide information about ancient migration patterns.[7] Morten Rasumssen and Sarah L. Anzick et al. sequenced the mitochondrial DNA of Anzick-1 and determined that the infant represents an ancient migration to North America from Siberia. They found that Anzick-1's mtDNA belongs to the haplogroup D4h3a, a "founder" haplogroup that might represent an early coastal migration route into the Americas.[1] The D haplogroup is also found in modern Native American populations, which provides a link between Anzick-1 and modern Native Americans.[8]
