Phenotypic variation across mammals is extensive and reflects their ecological
diversification into a remarkable range of habitats on every continent and in every ocean …

Hutchinson's n‐dimensional hypervolume concept for the interpretation of niches as
geometric shapes has provided a foundation for research across different fields of ecology …

The relationship between morphometrics and phylogenetic analysis has long been
controversial. Here we propose an approach that is based on mapping morphometric traits …

Understanding how and why certain clades diversify greatly in morphology whereas others
do not remains a major theme in evolutionary biology. Projecting families of phylogenies into …

The field of comparative morphology has entered a new phase with the rapid generation of
high-resolution three-dimensional (3D) data. With freely available 3D data of thousands of …

The ecological origin of snakes remains amongst the most controversial topics in evolution,
with three competing hypotheses: fossorial; marine; or terrestrial. Here we use a geometric …

Extant and fossil crocodilians have long been divided into taxonomic and/or ecological
groups based on broad patterns of skull shape, particularly the relative length and width of …

Factors intrinsic and extrinsic to organisms dictate the course of morphological evolution but
are seldom considered together in comparative analyses. Among vertebrates, squamates …

Insights into morphological diversification can be obtained from the ways the species of a
clade occupy morphospace. Projecting a phylogeny into morphospace provides estimates of …

Despite its importance to evolutionary theory, convergence remains an understudied
phenomenon and is usually investigated using qualitative data. This paper advances a new …
