How the time of divergence of two species can be estimated by a molecular clock. Concept introduction: All the living organisms have had a common ancestor. They all diverged from it with time forming new species. Thus as they diverged their genes changed too, this also the main reason for them to change phenotypically too. This change in DNA helps in the estimation of when a species diverged from another. This is called a molecular clock.
