“…This implied that the larger nodal values were associated with unusually high contrasts, i.e. taxa with higher character values systematically evolve faster (the opposite situation to the example given in Laurin et al. (2009)).…”

“…Further, preliminary analyses showed that differences between ML and independent contrasts ancestor values are small and the overall magnitude of the values and relative relationships are comparable; there are no significant differences between the ancestor values estimated by the two methods. Regardless of which method is employed, accurate branch durations are important (Laurin, 2004; Laurin et al. , 2009).…”

“…This is because both methods assume a Brownian motion model of evolution, where rates of character change per unit branch should follow a normal distribution across the phylogeny (Garland et al. , 1992; Laurin, 2004; Laurin et al. , 2009).…”

A key question in evolution is the degree to which morphofunctional complexes are constrained by phylogeny. We investigated the role of phylogeny in the evolution of biting performance, quantified as bite forces, using phylogenetic eigenvector regression. Results indicate that there are strong phylogenetic signals in both absolute and size‐adjusted bite forces, although it is weaker in the latter. This indicates that elimination of size influences reduces the level of phylogenetic inertia and that the majority of the phylogenetic constraint is a result of size. Tracing the evolution of bite force through phylogeny by character optimization also supports this notion, in that relative bite force is randomly distributed across phylogeny whereas absolute bite force diverges according to clade. The nonphylogenetically structured variance in bite force could not be sufficiently explained by species‐unique morphology or by ecology. This study demonstrates the difficulties in identifying causes of nonphylogenetically structured variance in morphofunctional character complexes.

“…This approach to time-scaling the phylogeny results in many zero-length internal branches (Bapst 2013). As has been commonly done in other molecular and morphological studies (e.g., Laurin et al 2009;Hopkins 2011), we add a small, arbitrary amount of time (0.01 Myr) to all zero-length branches in the terebratulide tree. We obtained radiometric ages of stage boundaries from the revised Devonian timescale of Ogg et al (2009).…”

Phylogenetic signal in extinction selectivity in Devonian terebratulide brachiopods

Determining which biological traits affect taxonomic durations is critical for explaining macroevolutionary patterns. Two approaches are commonly used to investigate the associations between traits and durations and/or extinction and origination rates: analyses of taxonomic occurrence patterns in the fossil record and comparative phylogenetic analyses, predominantly of extant taxa. By capitalizing upon the empirical record of past extinctions, paleontological data avoid some of the limitations of existing methods for inferring extinction and origination rates from molecular phylogenies. However, most paleontological studies of extinction selectivity have ignored phylogenetic relationships because there is a dearth of phylogenetic hypotheses for diverse non-vertebrate higher taxa in the fossil record. This omission inflates the degrees of freedom in statistical analyses and leaves open the possibility that observed associations are indirect, reflecting shared evolutionary history rather than the direct influence of particular traits on durations. Here we investigate global patterns of extinction selectivity in Devonian terebratulide brachiopods and compare the results of taxonomic vs. phylogenetic approaches. Regression models that assume independence among taxa provide support for a positive association between geographic range size and genus duration but do not indicate an association between body size and genus duration. Brownian motion models of trait evolution identify significant similarities in body size, range size, and duration among closely related terebratulide genera. We use phylogenetic regression to account for shared evolutionary history and find support for a significant positive association between range size and duration among terebratulides that is also phylogenetically structured. The estimated range size–duration relationship is moderately weaker in the phylogenetic analysis due to the down-weighting of closely related genera that were both broadly distributed and long lived; however, this change in slope is not statistically significant. These results provide evidence for the phylogenetic conservatism of organismal and emergent traits, yet also the general phylogenetic independence of the relationship between range size and duration.

“…Osteosclerosis observed in the histotypes IV may be produced by bone mass increase, which results in heavy, dense bone typical of slow swimmers living in shallow water Houssaye, 2009;Laurin et al, 2009;Laurin et al, 2011;Ricqlès and Buffrénil, 2001). The spongy condition present in the histotypes V is characteristic of open marine active swimmers (Houssaye et al, 2013(Houssaye et al, , 2014Ricqlès and Buffrénil, 2001).…”

a b s t r a c tThe histological framework of thirteen Early Permian tetrapod long bones from a single locality, the Briar Creek Bonebed in Archer County, Texas, USA, is described from a series of transverse sections through the midshafts. The bones were morphologically categorized and belong to one of three taxa: Eryops, Archeria, and Diadectes. However, five histotypes are recognized. The first category includes the juvenile bone. The second histotype is characterized by the presence of radial vascular canals. The third histotype is characterized by the numerous longitudinal canals arranged in regular rows. In the fourth histotype, there is strong remodeling in the deep part of the cortex, creating a distinct border with the external layer of lamellar bone. In the fifth histotype, the deep part of the cortex is progressively remodeled towards osteoporosis with distinct layers of large circumferentially arranged erosion cavities. For femora and humeri, histotypes match morphology. Histotype II is characteristic for Diadectes propodials, histotype III is characteristic for Eryops propodials, and histotype IV is characteristic for Archeria propodials. A discrepancy between morphology and histology is observed in the ulnae, fibula and radius. This discrepancy may be explained by interspecific or intraspecific variability.
