Developmental plasticity and the origin of tetrapods
The origin of tetrapods from their fish antecedents, approximately 400 million years ago, was coupled with the origin of terrestrial locomotion and the evolution of supporting limbs. Polypterus is aExpand

Polypterus and the evolution of fish pectoral musculature
Polypterus, a member of the most primitive living group of ray‐finned fishes, has demonstrated the ability to perform fin‐assisted terrestrial locomotion, a behavior that indicates a complex pectoralExpand

Locomotor flexibility of Polypterus senegalus across various aquatic and terrestrial substrates.
Amphibious fishes show wide variation in form and function. Examination of terrestrial locomotion in fishes has largely focused on highly specialized taxa. From an evolutionary perspective we areExpand

Dimensionality Reduction Techniques for Visualizing Morphometric Data: Comparing Principal Component Analysis to Nonlinear Methods
Principal component analysis (PCA) is the most widely used dimensionality reduction technique in the biological sciences, and is commonly employed to create 2D visualizations of geometricExpand

Integration and modularity of teleostean pectoral fin shape and its role in the diversification of acanthomorph fishes
Phenotypic integration and modularity describe the strength and pattern of interdependencies between traits. Integration and modularity have been proposed to influence the trajectory of evolution,Expand

Artificial turf infill associated with systematic toxicity in an amniote vertebrate
Significance Athletes and children are playing on artificial turfs. However, the health risk associated with exposure to crumb rubber from artificial turfs is unknown for higher vertebrates. Here, weExpand

First record of a hybodont shark (Chondrichthyes: Hybodontiformes) from the Lower Cretaceous of Colombia
The Mesozoic chondrichthyan fossil record from northern South America is scarce and poorly known containing only a few reports of lamniform and ptychodont species from the Upper Cretaceous ofExpand

Morphometric approaches to variation, variability, and constraints on phenotypic evolution
The properties of developmental systems that limit or bias the production of phenotypic variation, called structural or developmental constraints, can influence evolutionary responses to naturalExpand
