These include heterochronic mutations that alter structures by changing growth rates, homeotic mutations that change the identities of whole body parts, and paedomorphosis, which converts juvenile stages directly to adult ones.
Summed over time, such changes may lead to differences in Hox gene function between species that would be comparable to the effects of overt homeotic mutations - even though no such mutations need ever have been fixed.
