Divergence times in Caenorhabditis and Drosophila inferred from direct estimates of the neutral mutation rate.

Abstract excerpt

Accurate inference of the dates of common ancestry among species forms a central problem in understanding the evolutionary history of organisms. Molecular estimates of divergence time rely on the molecular evolutionary prediction that neutral mutations and substitutions occur at the same constant rate in genomes of related species. This underlies the notion of a molecular clock. Most implementations of this idea...
