Trait coevolution and causal inference using generalized dynamic phylogenetic models
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

The goal of this research was to illuminate the relationship between students’ acceptance and understanding of macroevolution. Our research questions were: (1) Is there a relationship between knowledge of macroevolution and acceptance of the theory of ...

Diversification rates and phenotypic evolution in venomous snakes (Elapidae) [PDF]
The relationship between rates of diversification and of body size change (a common proxy for phenotypic evolution) was investigated across Elapidae, the largest radiation of highly venomous snakes.

A NEO‐DARWINIAN COMMENTARY ON MACROEVOLUTION [PDF]
The neo-Darwinian synthesis that resulted from the integration of Mendelian genetics into evolutionary theory has dominated evolutionary biology for the last 30 to 40 years, due largely to its agreement with a huge body of experimental and observational data.

In macroevolution, the Red Queen (RQ) model posits that biodiversity dynamics depend mainly on species-intrinsic biotic factors such as interactions among species or life-history traits, while the Court Jester (CJ) model states that extrinsic ...

Ecological and geographical overlap drive plumage evolution and mimicry in woodpeckers
Many abiotic and biotic factors shape the macroevolution of phenotype, but these factors are rarely disentangled across large radiations. Here, Miller et al. investigate plumage evolution across woodpeckers, finding influences of habitat and climate, but

A comparative macrogenetic framework reveals that standardised landscape‐genomics can identify shared patterns reflecting common histories and assembly processes. We detected convergence in distributional dynamics and delineate three broad patterns and five species groups defined by gene flow and isolation‐by‐distance, highlighting the limitations of ...

Speciation History Shapes Patterns of Assemblage Species Richness in Birds
Speciation is the ultimate source of biodiversity. However, because most species arise in spatial isolation, how speciation shapes patterns of co‐occurring species richness remains unclear. Here we examine how the legacy of speciation affects contemporary biodiversity patterns via a phylogenetic model and show that this build‐up is remarkably slow and ...

The resource-use hypothesis proposed by Elisabeth S. Vrba suggests that lineages display varying tendencies toward generalism or specialization in biome occupancy, with a tendency towards the accumulation of specialists due to their higher rate of ...
