The paper investigates evolutionary transitions between pigmentary grey and non-iridescent structural blue in tanagers, identifying a new pathway through a transitional 'slate' color.

The paper introduces using neighbor-joining trees to quantify functional diversity, combining strengths of existing methods while avoiding their weaknesses.

The paper examines megaevolutionary patterns in bird beak diversity, finding that elaboration is common across scales while innovation drives major phenotypic changes through gradual processes.

The paper describes the discovery of endochondral bone in an Early Devonian placoderm-like fish, challenging previous assumptions about the evolution of bone in jawed vertebrates.

The paper analyzes cranial allometry in Australian rodents over 10 million years, finding conserved allometric patterns despite ecological diversity, with some exceptions in specialized diets.

The paper evaluates disparity and dissimilarity metrics for quantifying trait-space occupancy and introduces a tool to help select appropriate metrics based on data and research questions.

This study shows that individual variation in the masticatory system dominates 3D skull shape in wombats, challenging the idea that allometry primarily drives shape variation in marsupials.

The paper introduces an algorithm for ancestral states reconstruction in morphological phylogenetic datasets with inapplicable data, showing it identifies different optimal trees compared to traditional methods.
