Fossils provide the principal basis for temporal calibrations, which are critical to the accuracy of divergence dating analyses. Translating fossil data into minimum and maximum bounds for calibrations is the most important-often least appr...

When multiple speciation events occur rapidly in succession, discordant genealogies due to incomplete lineage sorting (ILS) can complicate the detection of introgression. A variety of methods, including the [Formula: see text]-statistic (a....
A New Hierarchy of Phylogenetic Models Consistent with Heterogeneous Substitution Rates [0.03%]
一种新的与异质替代率一致的系统发育模型层次结构

When the process underlying DNA substitutions varies across evolutionary history, some standard Markov models underlying phylogenetic methods are mathematically inconsistent. The most prominent example is the general time-reversible model (...

Most existing methods for modeling trait evolution are univariate, although researchers are often interested in investigating evolutionary patterns and processes across multiple traits. Principal components analysis (PCA) is commonly used t...
What's in an Outgroup? The Impact of Outgroup Choice on the Phylogenetic Position of Thalattosuchia (Crocodylomorpha) and the Origin of Crocodyliformes [0.03%]
圈外群什么样？圈外群选择对thalattosuchia（鳄形类）系统发育位置及crocodilyformes起源的影响是什么？

Outgroup sampling is a central issue in phylogenetic analysis. However, good justification is rarely given for outgroup selection in published analyses. Recent advances in our understanding of archosaur phylogeny suggest that many previous ...
On the Robustness to Gene Tree Estimation Error (or lack thereof) of Coalescent-Based Species Tree Methods [0.03%]
基于基因树的物种树方法（或缺乏）对基因树估算误差的稳健性分析

The estimation of species trees using multiple loci has become increasingly common. Because different loci can have different phylogenetic histories (reflected in different gene tree topologies) for multiple biological causes, new approache...
Taxonomy and Phylogeny Can Yield Comparable Results in Comparative Paleontological Analyses [0.03%]
分类学和系统发育能够产生可比的结果以进行比较古生物学分析

Many extinct taxa with extensive fossil records and mature taxonomic classifications have not yet been the subject of formal phylogenetic analysis. Here, we test whether the taxonomies available for such groups represent useful (i.e., non-m...

Whether biotic or abiotic factors are the dominant drivers of clade diversification is a long-standing question in evolutionary biology. The ubiquitous patterns of phylogenetic imbalance and branching slowdown have been taken as supporting ...
Approximate Bayesian Computation Reveals the Crucial Role of Oceanic Islands for the Assembly of Continental Biodiversity [0.03%]
近似贝叶斯计算揭示了海洋岛屿在大陆生物多样性形成中的关键作用
Jairo Patiño,Mark Carine,Patrick Mardulyn et al.
Jairo Patiño et al.
The perceived low levels of genetic diversity, poor interspecific competitive and defensive ability, and loss of dispersal capacities of insular lineages have driven the view that oceanic islands are evolutionary dead ends. Focusing on the ...
Phylogenetic Comparative Methods for Evaluating the Evolutionary History of Function-Valued Traits [0.03%]

Phylogenetic comparative methods offer a suite of tools for studying trait evolution. However, most models inherently assume fixed trait values within species. Although some methods can incorporate error around species means, few are capabl...
