The neutrality theory predicts that the rate of neutral molecular
evolution is constant over time, and thus that there is a molecular
clock for timing evolutionary events. It has been observed that the
variance of the rate of evolution is generally larger than expected
according to the neutrality theory, which has raised the question of
how reliable the molecular clock is or, indeed, whether there is a molecular clock at all.
