Abstract excerpt
The relative importance of protein function change and gene expression change in phenotypic evolution is a contentious, yet central topic in evolutionary biology. Analyzing 5,199 mouse genes with recorded mutant phenotypes, we find that genes exclusively affecting morphological traits when mutated (dubbed "morphogenes") are grossly enriched with transcriptional regulators, whereas those exclusively affecting...
