Incorporating morphological data into modern phylogenies allows integration of fossil
evidence, facilitating divergence dating and macroevolutionary inferences. Improvements in …

An accurate classification is the basis for research in biology. Morphometrics and
morphospecies play an important role in modern taxonomy, with geometric morphometrics …

The degree to which the ontogeny of organisms could facilitate our understanding of
phylogenetic relationships has long been a subject of contention in evolutionary biology …

Birds are the most diversified forms of modern terrestrial vertebrates. They are archosaurs,
and are related to Theropoda within Dinosauria. Even though bird morphology has been a …

Phylogenetic reconstruction based on morphometric data is hampered by homoplasies. For
example, many similarities in cranial form between primate taxa more strongly reflect …

Marsupials represent a major mammalian diversification today restricted geographically to
the Americas (but chiefly to the Neotropical Region) and Australasia. The group is highly …

Background In contrast to placental neonates, in which all cranial bones are ossified,
marsupial young have only the bones of the oral region and the exoccipital ossified at birth …

Recently, González-José et al.(2008) proposed that phylogeny estimation using principal
components (PCs) from shape analyses of cranial 'modules'(modular cladistic approach …

Large-scale molecular datasets have generally outperformed morphological data for
inferring phylogeny, and sources of error in the latter are poorly understood. The …

Geometric morphometrics is a powerful tool for the quantification, visualization and analysis
of morphological variation and change. This approach is being applied more frequently in a …
