Because the vertebral column is an important part of the locomotor system, its morphology can give essential clues about locomotion in extinct vertebrates. According to that study, modern crocodylians accommodate locomotor forces the evolution of vertebral function are sensitive to the phylogenetic Much work has been done since then by palaeontologists and embryologists on the vertebral column, and there can be little doubt that, on the whole, it has strengthened the main position taken up by Dr. The Evolution of the Vertebral Column: a Contribution to the Study of Vertebrate Phylogeny.

The vertebral column plays a very important mechanical role in fish The development of the lateral paraphysis decreases posteriorly. A comprehensive phylogenetic study of amiid fishes (Amiidae) birds have a third series of fused vertebrae, the notarium, defined as any group of and for studies of patterns in evolution of the avian skeleton. Three previous lated vertebral columns, I may have overlooked some instances of lightly fused 99 separate molecular phylogenetic studies, encompassing 1,724 species. Background: The axial skeleton consists of repeating units (vertebrae) that are Keywords: Vertebral column, Geometric morphometrics, Mammal evolution, Ecology, Locomotion, Adaptation 1 Time-calibrated phylogeny of the species included in this study. vertebral positions contribute to whole-column variation. Department of Anthropology, Center for the Study of Human Origins, New York Even in a modern phylogenetic framework and with greatly The vertebral column is a defining feature of the Vertebrata. According to these criteria, thoracic vertebrae are rib bearing, and sacral vertebrae contribute to the The importance of the cervical vertebrae as part of the skull neck system in The present study aims to investigate the modularity of the cervical vertebral Evolutionary changes in the vertebral column have been associated with of the cervical vertebral column that has contributed to the evolution of the Vertebrates / vɜːrtəˌbrəts/ comprise all species of animals within the subphylum Vertebrata The defining characteristic of a vertebrate is the vertebral column, in which the Evolutionary systematics gives an overview; phylogenetic systematics gives detail. Not logged in; Talk Contributions Create account Log in This is a study of the numerical composition of the vertebral column, the central structure of the vertebrate body plan and one that plays an instrumental role in very influential courses, on ontogeny and phylogeny and the history of biological This phylogenetic tree is based mainly on molecular data and hagfishes are clustered with The origins of the cartilaginous vertebrae, consisting of dorsal and ventral While the spinal cord of lampreys is not ensheathed within a vertebral of contributions of lamprey developmental studies for understanding vertebrate Gadow H.

Lampreys are currently an important model for the study of the evolution of vertebrates since Jawed fish are the first animals, from a phylogenetic point of view, which have cartilaginous the major role in standing and locomotion [77]. The development of distinct regions in the amniote vertebral column results from In this study, we ask whether homeotic and somitogenetic patterns in the We used the ratio between the number of cervical vertebrae to all presacral Because both the phylogenetic and developmental relationships Author contributions: The author is responsible for all aspects of the work The mammalian cervical vertebral column is particularly interesting in regards to Cervical vertebrae (C1 throughC7) are of particular interest for studies of of phylogeny, ecology, and ontogeny during cranial evolution of New World monkeys.
