Antiquity of mtDNA lineage D1g from the southern cone of South America supports pre-Clovis migration

The discovery of the Monte Verde site was revolutionary; it led to wide acceptance of the pre-Clovis hypothesis and its corollary, the coastal migration route. Although numerous additional pre-Clovis sites have been reported in South America, debate continues about the timing of the earliest human migration. Perhaps because of the paucity of very early sites in North America, researchers there are increasingly focused on the genomic evidence.

A new subhaplogroup of native American Y‐Chromosomes from the Andes

To identify new single nucleotide polymorphisms (SNPs) and increase the phylogenetic resolution of the major haplogroup Q found in the Americas, we have performed a search for new polymorphisms based on sequencing divergent Y chromosomes identified by microsatellite haplotype analysis.
