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.

This is one article of a series on using DNA for genealogical research. There are several. types of DNA tests offered for genealogical purposes. Researchers must understand that. only like tests can be compared: Y-DNA to Y-DNA, mitochondrial DNA (mtDNA) to. mtDNA, and autosomal DNA (atDNA) to autosomal DNA. To use DNA to solve a. problem, an understanding of DNA inheritance and the limits of the evidence is paramount. This article covers atDNA.
