Abstract excerpt
Evolution may depend more strongly on variation in gene expression than on differences between variant forms of proteins. Regions of DNA that affect gene expression are highly variable, containing 0.6% polymorphic sites. These naturally occurring polymorphic nucleotides can alter in vivo transcription rates. Thus, one might expect substantial variation in gene expression between individuals. But the natural...
