(July 2010). Molecular anthropology is a field of anthropology in which molecular analysis is used to determine evolutionary links between ancient and modern human populations, as well as between contemporary species.itochondrial DNA offers another advantage over autosomal DNA. There are generally 2 to 4 copies of each chromosome in each cell (1 to 2 from each parent chromosome). For mtDNA there can be dozens to hundreds in each cell.
While research is one possible use of genetic information, this information can also be used to examine how people are related to one another by comparing the similarity of their DNA sequences. Genetic information can also provide clues to ancestral relations. DNA is obtained by collecting biological samples (e.g., blood, hair, cells from a cheek swab, or even from spitting in a cup). Genetic testing has been advertised to tribes as a tool for determining their enrollment (TallBear 2003).NA is obtained by collecting biological samples (e. g., blood, hair, cells from a cheek swab, or even from spitting in a cup).
