Overdispersed molecular evolution in constant environments.

Abstract excerpt

According to recent data analysis of DNA sequences, the dispersion index, defined as the variance-to-mean ratio of the number of base substitutions in a lineage, is often much larger than unity, which is in conflict with simple Poisson processes assumed in the molecular clock hypothesis. In this...
