GC-biased gene conversion conceals the prediction of the nearly neutral theory in avian genomes
GC-biased gene conversion conceals the prediction of the nearly neutral theory in avian genomes
The nearly neutral theory of molecular evolution predicts that the efficacy of natural selection increases with the effective population size. This prediction has been verified by independent observations in diverse taxa, which show that life-history traits are strongly correlated with measures of the efficacy of selection, such as the dN/dS ratio.
