It is true that by calculating genetic
distance, and using rate of change from molecular clock, researchers can
estimate when two lineages diverged.
To add, genetic distance<span> is the term
used to describe the number of differences or mutations between two sets of
Y-chromosome DNA or mitochondrial DNA test results. Having zero genetic distance equates to having
an exact match and that there’s no differences in the two results presented. A lot of people mistakenly assume that genetic
distance is the number of generations to a common ancestor, but that is NOT AT ALL what genetic
distance means. Genetic distance can also be identified by how many a particular
match’s mutation difference to the participant.</span>
