Abstract: | Background There is spectacular morphological diversity in nature but lineages typically display a limited range of phenotypes. Because
developmental processes generate the phenotypic variation that fuels natural selection, they are a likely source of evolutionary
biases, facilitating some changes and limiting others. Although shifts in developmental regulation are associated with morphological
differences between taxa, it is unclear how underlying mechanisms affect the rate and direction of evolutionary change within
populations under selection. |
