Texte intégralEvolution is the result of two main factors: the environment and the development. In this context, untangling the impact of these two forces on the morphological evolution of a structure is of major importance. To do so, studying evolution in deep time is useful, as it is the only way to observe the mechanisms in action over a long time interval and the responses to major environmental variations. In this thesis, we aim to better understand the evolution of a fossil species: the conodont. These marine jawless vertebrates possess a feeding apparatus composed of mineralized structures comparable to teeth, called conodont elements. Their high evolutionary rate, their long and sub-continuous fossil record, and their large populations made them a relevant model to conduct evolutionary studies in deep time. In the literature, only a few studies attempt to quantify the shape of conodont elements, and never in a developmental framework. With the discovery of new exceptionally preserved fossils, and the establishment of a methodology to quantify the patterns of morphological variation and covariations in these elements, the morphological evolution of conodont elements have been studied from different angles. We have established the existence of covariations between some morphological characters, illustrating the constraints on possible morphologies. Some constraints are considered developmental, while others are potentially mechanical. Evolutionary directions are highlighted, channelled by developmental constraints. At the inter-genera scale, we demonstrated a relationship between environmental changes (especially temperature variations) and these evolutionary directions. The results revealed a combined effect of the developmental forces (that constrain the initial possible morphologies) and the evolutionary forces (selecting the fittest morphologies depending on conditions) in the conodont elements evolution. We proposed heterochrony as underlying mechanism for these patterns, potentially driven by oceanic temperature. Shape quantification is also used in an attempt to clarify the neogondolellids taxonomy of the early Triassic. This work demonstrates the conodont's potential as model organism to study evolution in deep time

Texte intégralThis thesis dissertation is dedicated to the study of craniofacial structures within the hominid family. Throughout evolution, a reduction of facial prognathism and a diminution of the facial length are observed in the taxa which belong to the human lineage. This reduction of facial structures is associated to a more flexed cranial base and to a shorter mandible. The aim of this work is to define the role played by the basicranial and mandibular changes in the set up of the short and straight face of modern humans. In this context, the patterns of integration linking the face and the other cranial structures (basicranium and mandible) are decrypted and quantified in this thesis dissertation. This work has been done with a sample including all the extant hominid genera: modern humans, chimpanzees, gorillas, orang-utans. The skulls were first scanned using a medical scanner. Patterns of craniofacial integration were then studied using statistical tools and geometric morphometric analysis methods. This work underlined several mechanisms of craniofacial integration, unique to modern humans. These specific patterns of integration can explain an important part of the set up of modern humans reduced face. Thus, these results enlighten the evolution mechanisms and the set up of facial structures in hominids and in the human lineage
