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.
To understand the science behind how this could work, the following video is very helpful. Essentially, DNA can be used in much the same way as any other programming language. The field of genetic engineering adds more of what we typically think of from engineering to create synthetic biology. As one could design a computer and a software program, one could also design a chair that would grow itself - the chair has the computer and the software program as part of itself.
