Evolution of Mammalian Molar Teeth to and from the triangular type (Biological Studies and Addresses Vol. I)

ix, 250, 215 text figs. . HB. 8vo, orig. cloth, gilt title to front board and spine, some wear to head/foot of spine. Withdrawn from an institutional library with a few neat ink stamps. Good. Including collected and revised researches on trituberculy and new sections on the forms and homologies of the molar teeth in the different orders of mammals. First edition. A landmark early study, Osborn’s classic monograph offers one of the first comprehensive examinations of how mammalian molar teeth developed from ancestral forms. Introducing influential concepts such as the tritubercular theory, the work helped shape early 20th-century thinking on dental evolution. Though many of its conclusions have since been revised by modern research, the book remains an important historical reference, valued for its detailed comparative observations and its role in the development of evolutionary morphology.
