Phylogenetic Analysis of Pelecaniformes (Aves) Based on Osteological Data: Implications for Waterbird Phylogeny and Fossil Calibration Studies
BACKGROUND Debate regarding the monophyly and relationships of the avian order Pelecaniformes represents a classic example of discord between morphological and molecular estimates of phylogeny. This lack of consensus hampers interpretation of the group's fossil record, which has major implications for understanding patterns of character evolution (e.g., the evolution of wing-propelled diving) a...
متن کاملAvian extinction at the end of the Cretaceous: Assessing the magnitude and subsequent explosive radiation
Debate on the magnitude of Cretaceous extinctions and timing of modern bird origins has sharply coalesced over the past two decades into contested models, gradualistic or explosive. Molecular clocks, bolstered by phylogenetic, biogeographic, and vicariance models, support an Early Cretaceous origin for birds and mammals over 100 million years ago. Yet, although numerous new Chinese fossils of a...
متن کاملMolecular phylogeny of some avian species using Cytochrome b gene sequence analysis
Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...
متن کاملPairwise difference analysis in modern human origins research.
Pairwise difference analysis is a phenetic method that groups taxa on the basis of the number of differences they exhibit. Recently, pairwise difference analysis has been used to investigate the phylogenetic relationships of hominid fossils at the centre of the modern human origins debate. It has been argued that the results of these analyses disprove the African replacement model of modern hum...
متن کاملFirst Evidence of Dinosaurian Secondary Cartilage in the Post-Hatching Skull of Hypacrosaurus stebingeri (Dinosauria, Ornithischia)
Bone and calcified cartilage can be fossilized and preserved for hundreds of millions of years. While primary cartilage is fairly well studied in extant and fossilized organisms, nothing is known about secondary cartilage in fossils. In extant birds, secondary cartilage arises after bone formation during embryonic life at articulations, sutures and muscular attachments in order to accommodate m...
