Prevalent adaptive evolution of morphological traits in the yeast S. cerevisiae. (A) Mean evolution distance (ED) of 666 pairs of natural strains for a trait and the MS of the trait both decrease with TI. Each dot represents a trait. ρ, Spearman’s rank correlation coefficient. (B) Mean ED among 666 natural strain pairs for a trait relative to its MS increases significantly with TI, while the mean ED between 666 gene deletion strains and the wild type relative to MS does not increase significantly with TI. (C) Nominal P values for the Spearman’s correlation between ED/MS and TI for all 666 pairs of natural strains. The horizontal colored bars above the strain names show the ecological environments of the strains. Ba, bakery; Be, beer.
