Abstract

A molecular clock can be used to date the origin of species assuming a constant rate of DNA change. But the reliability of molecular clocks has been questioned, due to the discrepancy between molecular dates and fossil evidence for major radiations, leading to claims that rapid evolutionary diversification speeds molecular evolution. This program provides an empirical test of these claims, by comparing rates of molecular evolution in a broad range of genes and organisms, testing the effect of body size, rapid morphological change, speciation rate or ecological divergence on DNA substitution rates. The results will test the reliability of molecular clocks and aid development of methods that allow variation in rate of molecular evolution.
