The molecular clock is a technique that uses the mutation rate of biomolecules to
deduce the time in prehistory when two or more life forms diverged.
Since its proposal in the 1960s, the molecular clock has become an essential tool
in many areas of evolutionary biology, including systematics, molecular ...
