A number of well-understood mechanisms, including single gene mutations, produce changes that qualify as macroevolution. 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.
