The macroevolutionary consequences of phenotypic integration: from development to deep time
TLDR
It is demonstrated that phenotypic integration can produce both more and less disparate organisms than would be expected under random walk models by repartitioning variance in preferred directions, and that this effect can also be expected to favour homoplasy and convergent evolution. Expand
Multigenic and morphometric differentiation of ground squirrels (Spermophilus, Scuiridae, Rodentia) in Turkey, with a description of a new species.
TLDR
The potential of combined molecular and morphometric studies to uncover new Anatolian species and to reconstruct their phylogeographic history is illustrated and the new species is important for squirrel taxonomy and for understanding Eurasian mammal evolution. Expand
Giant boid snake from the Palaeocene neotropics reveals hotter past equatorial temperatures
TLDR
Depositional environments and faunal composition of the Cerrejón Formation indicate an anaconda-like ecology for the giant snake, and an earliest Cenozoic origin of neotropical vertebrate faunas. Expand
Limbs in Mammalian Evolution
The more than 4,000 living species of mammal have infiltrated almost every habitat in the world. From alpine mountaintops to plains grasslands, from aerial heights to the depths of the ocean, fromExpand
Variability in mammalian dentitions: size-related bias in the coefficient of variation
TLDR
The coefficient of variation has been used in many evolutionary studies but a strong negative correlation between this index and size may artificially inflate the apparent variability of small traits, which is likely to affect conclusions. Expand
The Influence of Modularity on Cranial Morphological Disparity in Carnivora and Primates (Mammalia)
TLDR
Within Primates and Carnivora, there was some support for the hypothesis that integration of traits within cranial modules limits morphological evolution, presumably by limiting the variation of individual traits. Expand
The skeleton of Gazinocyon vulpeculus gen. et comb. nov. and the cladistic relationships of Hyaenodontidae (Eutheria, Mammalia)
TLDR
Cladistic analysis suggests that Gazinocyon was related to a clade containing Eurotherium, Propterodon, Hyaenodon, and “Pterodon” hyaenoides, and suggests that Hyaeenodontinae (containing Pterodus, Hy... Expand
Developmental Dynamics and G-Matrices: Can Morphometric Spaces be Used to Model Phenotypic Evolution?
TLDR
Concerns exist whether simulations of phenotypic changes directly in morphospaces is realistic because trajectories traced in such spaces describe continuous gradations in the phenotype and because the gain and loss of structures is often impossible because morphospace are necessarily constructed from variables shared in common by all the phenotypes being considered. Expand
Evolutionary biology: Development with a bite
Predictions drawn from experiments on the growth of molar teeth in mice, and applied to a wide range of related species, provide a remarkable connection between developmental and evolutionary biology.
PHYLOGENETIC AND ENVIRONMENTAL COMPONENTS OF MORPHOLOGICAL VARIATION: SKULL, MANDIBLE, AND MOLAR SHAPE IN MARMOTS (MARMOTA, RODENTIA)
The phenotype is a product of its phylogenetic history and its recent adaptation to local environments, but the relative importance of the two factors is controversial. We assessed the effects ofExpand
