Neither Williston nor Dollo: mandibular complexity from stem tetrapods to modern amphibians
E. C. Watt, R. N. Felice, A. Goswami
This study examines evolutionary trends in tetrapod mandibles, finding that neither Willistons law of simplification nor Dollos law of irreversibility holds, as jaw complexity and component gains/losses are not consistently decreasing or irreversible.
