The molecular clock (based on the molecular clock hypothesis (MCH)) is a
technique in molecular evolution that uses fossil constraints and rates of
Molecular Clocks. For the past 40 years, evolutionary biologists have been
investigating the possibility that some evolutionary changes occur in a clock-like
Since its proposal in the 1960s, the molecular clock has become an essential tool

But a molecular clock does tell time—on an epoch scale.
The molecular clock hypothesis originally restedon the assumption of rate
constancy across lineages of a phylogeny, which would produce an
Such proteins can be used as ``molecular clocks,'' since one can use them to
estimate when species diverged. However, these clocks sometimes behave in an
