The Molecular Clock and Estimating Species Divergence
What is the molecular clock? Levels of molecular variation could be used, in principle, to estimate divergence times, serving as evolutionary "clocks" that "tick" at different rates. Subsequent ...

Neutrality and Molecular Clocks
The term 'molecular clock' was coined to describe the phenomenon, comparing the manner in which sequence changes occur to regular ticks of a clock. Is there really such a molecular clock?
