Today, in Science, an international team of geneticists, evolutionary biologists, and statisticians concluded that all Native Americans descended from a single immigration event out of Siberia. The team looked at the DNA from 110 modern Native Americans and 23 who died 200 to 6,000 years ago and compared their genomes to those of more than 3,000 individuals from around the world.
One of the lead authors is María Ávila-Arcos, PhD, a postdoctoral researcher in the lab of Stanford professor of genetics Carlos Bustamante, PhD. Ávila-Arcos led many of the statistical analyses for the paper, including comparison of whole human genomes from diverse Native American populations—both modern and ancient. Bustamante is also a co-author, along with Stanford professor of structural biology and of microbiology and immunology, Peter Parham, PhD, five other Stanford researchers, and dozens of researchers from around the world.
