Rates at which AP-PCR patterns diverge among isolated taxa were examined to
test whether they exhibit clocklike regularity. The results showed that
rates of divergence differed significantly among the groups examined
(primates, antelopes, and Hawaiian Drosophila grimshawi). Therefore, AP-PCR
divergence rates cannot be used as a "universal clock" with an invariant
rate in all animals. Nevertheless, within each group, a strong relationship
existed between degree of AP-PCR pattern divergence and time since
separation of isolated taxa. Thus, AP-PCR divergence may prove useful for
dating evolutionary events if calibrated within a more limited taxon.
