The Integration Of Morphology, Variation, And Phylogenetics To Better Understand Fossil Taxa And Their Modern Relatives [PDF]

, 2018
Morphology, or shapes, particularly of bones, is important for understanding how animals vary and, therefore, for understanding diversity. Comparison of morphology in animals can be used to make inferences on fossil organisms.
