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.
Molecular Clocks. For the past 40 years, evolutionary biologists have been
investigating the possibility that some evolutionary changes occur in a clock-like

But a molecular clock does tell time -- on an epoch scale.

The hypothesis of a molecular clock asserts that the rate of DNA or protein
sequence evolution is constant over time or among evolutionary lineages. In the
