Many ecological and evolutionary studies seek to explain patterns of shape variation and its
covariation with other variables. Geometric morphometrics is often used for this purpose …

Morphometric analysis of biogenic recording structures within marine organisms has
applications in stock assessment, taxonomics, and ecomorphological studies, with shape …

An accurate understanding of species diversity is essential to studies across a wide range of
biological subdisciplines. However, delimiting species remains challenging in evolutionary …

The largest source of empirical data on the history of life largely derives from the marine
invertebrates. Their rich fossil record is an important testing ground for macroecological and …

Shape measurements are crucial for evolutionary and developmental biology; however, they
present difficulties in the objective and automatic quantification of arbitrary shapes …

Studies of bone surface modifications (BSMs) such as cut marks are crucial to our
understanding of human and earlier hominin subsistence behavior. Over the last several …

Evolutionary adaptation to novel, specialized modes of life is often associated with a close
mapping of form to the new function, resulting in narrow morphological disparity. For bivalve …

Snakes are a highly successful group of vertebrates, within great diversity in habitat, diet,
and morphology. The unique adaptations for the snake skull for ingesting large prey in more …

Bivalves protect themselves from predators using both mechanical and behavioral defenses.
While their shells serve as mechanical armor, bivalve shells also enable evasive behaviors …

Directional evolution is one of the most compelling evolutionary patterns observed in
macroevolution. Yet, despite its importance, detecting such trends in multivariate data …
