Phylogenomics and Pervasive Genome-Wide Phylogenetic Discordance Among Fin Whales (Balaenoptera physalus) [0.03%]
鳁鲸的系统基因组学及其全基因组范围的系统发育分歧性研究
Fabricio Furni,Eduardo R Secchi,Camilla Speller et al.
Fabricio Furni et al.
Phylogenomics has the power to uncover complex phylogenetic scenarios across the genome. In most cases, no single topology is reflected across the entire genome as the phylogenetic signal differs among genomic regions due to processes, such...
Persistent Gene Flow Suggests an Absence of Reproductive Isolation in an African Antelope Speciation Model [0.03%]
基因流动持续存在暗示非洲长颈鹿进化模型中不存在生殖隔离现象
Xi Wang,Casper-Emil Tingskov Pedersen,Georgios Athanasiadis et al.
Xi Wang et al.
African antelope diversity is a globally unique vestige of a much richer world-wide Pleistocene megafauna. Despite this, the evolutionary processes leading to the prolific radiation of African antelopes are not well understood. Here, we seq...
PhyloJunction: A Computational Framework for Simulating, Developing, and Teaching Evolutionary Models [0.03%]
PhyloJunction：一个用于模拟、开发和教学进化模型的计算框架

We introduce PhyloJunction, a computational framework designed to facilitate the prototyping, testing, and characterization of evolutionary models. PhyloJunction is distributed as an open-source Python library that can be used to implement ...
Adaptive Radiation Without Independent Stages of Trait Evolution in a Group of Caribbean Anoles [0.03%]
加勒比壁虎适应辐射过程中性状演变没有独立阶段
Brooke Bodensteiner,Edward D Burress,Martha M Muñoz
Brooke Bodensteiner
Adaptive radiation involves diversification along multiple trait axes, producing phenotypically diverse, species-rich lineages. Theory generally predicts that multi-trait evolution occurs via a "stages" model, with some traits saturating ea...
Bayesian Inference Under the Multispecies Coalescent with Ancient DNA Sequences [0.03%]
基于古DNA序列的多重共祖模型中的贝叶斯推断
Anna A Nagel,Tomáš Flouri,Ziheng Yang et al.
Anna A Nagel et al.
Ancient DNA (aDNA) is increasingly being used to investigate questions such as the phylogenetic relationships and divergence times of extant and extinct species. If aDNA samples are sufficiently old, expected branch lengths (in units of nuc...
Complex but Clear Allopolyploid Pattern of Subtribe Tussilagininae (Asteraceae: Senecioneae) Revealed by Robust Phylogenomic Evidence, with Development of a Novel Homeolog-Sorting Pipeline [0.03%]
基于稳健的系统基因组学证据揭示紫菀族风毛菊亚属(Tussilagininae)复杂的异源多倍体模式及开发新的同源排序流程
Chen Ren,Long Wang,Ze-Long Nie et al.
Chen Ren et al.
Polyploidy is a significant mechanism in eukaryotic evolution and is particularly prevalent in the plant kingdom. However, our knowledge about this phenomenon and its effects on evolution remains limited. A major obstacle to the study of po...
Exploring the Macroevolutionary Signature of Asymmetric Inheritance at Speciation [0.03%]
探讨不对称遗传在物种形成中的宏进化印记
Thèo Gaboriau,Joseph A Tobias,Daniele Silvestro et al.
Thèo Gaboriau et al.
Popular comparative phylogenetic models such as Brownian Motion, Ornstein-Ulhenbeck, and their extensions, assume that, at speciation, a trait value is inherited identically by two descendant species. This assumption contrasts with models o...
Inferring Taxonomic Affinities and Genetic Distances Using Morphological Features Extracted from Specimen Images: A Case Study with a Bivalve Data Set [0.03%]
基于标本图像的形态特征推理分类亲缘关系和基因距离：与瓣鳃动物数据集相关的案例研究
Martin Hofmann,Steffen Kiel,Lara M Kösters et al.
Martin Hofmann et al.
Reconstructing the tree of life and understanding the relationships of taxa are core questions in evolutionary and systematic biology. The main advances in this field in the last decades were derived from molecular phylogenetics; however, f...
Blouch: Bayesian Linear Ornstein-Uhlenbeck Models for Comparative Hypotheses [0.03%]
布洛赫：比较假设的贝叶斯线性奥恩斯坦-乌伦贝克模型
Mark Grabowski
Mark Grabowski
Relationships among species in the tree of life can complicate comparative methods and testing adaptive hypotheses. Models based on the Ornstein-Uhlenbeck process permit hypotheses about adaptation to be tested by allowing traits to either ...
Topology Testing and Demographic Modeling Illuminate a Novel Speciation Pathway in the Greater Caribbean Sea Following the Formation of the Isthmus of Panama [0.03%]

Benjamin M Titus,H Lisle Gibbs,Nuno Simões et al.
Benjamin M Titus et al.
Recent genomic analyses have highlighted the prevalence of speciation with gene flow in many taxa and have underscored the importance of accounting for these reticulate evolutionary processes when constructing species trees and generating p...
