Thirty years ago the first ancient DNA studies have began. New methodologies have facilitated the task and ancient genomes can now be analyzed. The knowledge has accumulated in the field of the so-called paleogenetic that enable us to better understand the genetic relation between H. sapiens and H. neanderthalensis. Archaeogenetic in American samples has confirmed the Asian origin of Native Americans, establishing five founder maternal lineages for North America (A, B, C, D and X). For South America, the first four lineages are present A, B, C and D. Analyses of samples from Argentina shows a particular distribution, high B haplogroup frequencies in North west, and decreasing presence A and B towards the South, with a concomitant increase of C and D haplogroups, which are the only described so far in Tierra del Fuego. The analysis of specimens from Rosa Novak Museum from San Julián, in Santa Cruz Province, also demonstrated C and D haplogroups in Southern Patagonia.

Abstract
For several decades, biological anthropology has employed different molecular markers in population
research. Since 1990 different techniques in molecular biology have been developed allowing preserved DNA
extraction and its typification in different samples from museums and archaeological sites. Ancient DNA studies
related to archaeological issues are now included in the field of Archaeogenetics. In this work we present some of ancient DNA applications in archaeology. We also discuss advantages and limitations for this kind of research
and its relationship with ethic and legal norms.
Key words: Archaeogenetics, Ancient DNA, American Peopling, Ethics.
