Abstract

Recent studies have provided strong evidence for significant variation in rates of nucleotide substitution among evolutionary lineages. They have also provided evidence for germ-cell division as a major source of mutation (i.e. the generation-time effect hypothesis). Moreover, they have suggested the importance of differences in metabolic rate as a cause of rate variation.
