By analyzing three independent hybrid zones between *Ischnura elegans* and *Ischnura graellsii*, this study reveals that while demographic history drives geographic heterogeneity in introgression patterns, genomic architecture imposes consistent constraints, resulting in repeatable functional outcomes rather than identical gene flow across zones.
This study demonstrates that two distinct ecotypes of the wood-decay fungus *Meruliopsis taxicola* exhibit contrasting ecological strategies, with the Continental ecotype favoring competitive growth and decomposition while the Coastal ecotype prioritizes stress tolerance, a divergence that is largely maintained in their hybrid offspring.
This paper introduces *demestats*, a differentiable software library that computes first-coalescence and cross-coalescence rates for complex demographic models to overcome the limitations of pairwise summaries in resolving recent population history, demonstrating improved accuracy in simulations and new insights into human expansion using 1000 Genomes Project data.
The paper introduces B-STILL, a scalable hierarchical Bayesian framework that resolves the "zero-rate origin" gap in evolutionary analysis by distinguishing stochastic invariance from functional constraint to identify Evolutionary Stasis Anchors (ESAs), thereby transforming previously ignored invariant sites into high-resolution markers of extreme purifying selection across viral and mammalian genomes.
This study demonstrates that while transgenerational epigenetic inheritance of pathogen avoidance occurs in some *Caenorhabditis* species like *C. elegans* and *C. remanei*, it is not a universal response across the genus, highlighting the species-specific nature of this adaptive mechanism.
This study employs an adaptive dynamics model to demonstrate that trade-offs between emergence timing and competitiveness, combined with variance asymmetry between sexes, drive the evolutionary branching of male emergence timing into discrete dimorphic or multimorphic strategies, offering a theoretical explanation for the coexistence of early-small and late-large male morphs in insects.
This study demonstrates that analyzing convergent evolution in large phylogenies can predict major antigenic shifts in H3N2 influenza viruses over a year in advance by identifying specific receptor-binding site substitutions under positive selection before they become dominant.
This study demonstrates that the effectiveness of agricultural management in reducing global crop yield loss is significantly moderated by the relative evolutionary potential of pests and crops, with the interaction between these evolutionary factors explaining as much variation in damage as management practices themselves.
This study characterizes the unique ptychocyte of the tube anemone *Ceriantheopsis americana*, revealing its distinct morphology, role in tube construction, and slower firing kinetics compared to nematocytes, thereby providing insights into the evolutionary diversification of cnidocytes.
By analyzing transcriptomic data from eleven newly cultivated free-living neobodonids, this study resolves the kinetoplastid phylogeny to demonstrate that neobodonids are a paraphyletic group serving as the evolutionary ancestor to all other metakinetoplastids.
This study demonstrates that the germline mutation rate in *Chironomus riparius* undergoes local adaptation to thermal environments, with Central European populations exhibiting plastic, temperature-dependent mutation rates while Mediterranean populations maintain robust, temperature-insensitive rates through evolved differences in ROS dynamics and DNA repair machinery.
This study establishes a robust phylogenomic framework for the genus *Vanilla* using 349 nuclear and 76 plastid loci to resolve taxonomic uncertainties, elucidate the roles of incomplete lineage sorting and hybridization in its evolution, and reconstruct its historical biogeography originating from the Guiana Shield with subsequent diversification across the Americas.
This paper introduces a spectral existence criterion, expressed as the inequality , to unify the evolution of cooperation across various population structures and demonstrate how Nowak's five rules emerge as specific scalar cases derived from the Price equation.
This study demonstrates that gene-level complexity, characterized by features such as connectivity, expression, and conservation, better explains genome-wide variation in the distribution of fitness effects across multiple species than organism-level labels, aligning empirical data with Fisher's geometric model predictions.
This study reveals that while the overall proportion of ion channels remained conserved during the vertebrate water-to-land transition, specific gene families underwent positive selection and significant genomic remodeling to facilitate critical physiological adaptations for terrestrial life.
By employing advanced phylogenomic analyses to reconstruct the last eukaryotic common ancestor's proteome, this study reveals that eukaryogenesis involved multiple waves of horizontal gene transfer from diverse bacterial donors and potentially Nucleocytoviricota viruses, suggesting that eukaryotes emerged through complex microbial associations rather than a single symbiotic event.
This study reveals that while Asgard archaea genomes are shaped by widespread prokaryotic-like horizontal gene transfer, their significantly larger size is primarily driven by eukaryotic-like gene duplications, offering new insights into the genomic transitions underlying eukaryogenesis.
This study demonstrates that in yeast adaptation to 5-fluorocytosine, the inability of single promoter mutations to drive rapid evolution results from the combined constraints of the distribution of mutational effect sizes on gene expression and the flat shape of the fitness function around wild-type expression levels, which necessitates a severe expression reduction unattainable by a single mutation.
A large common-garden experiment demonstrates that in the dioecious plant *Mercurialis annua*, selection during range expansion has favored increased leaky sex expression and reproductive effort at the colonization edge to ensure reproductive assurance and successful establishment.
By applying Pareto front analysis to both experimental evolution and macroevolutionary data, this study reveals that fundamental evolutionary constraints limit the simultaneous optimization of growth rate and niche-determining traits in phytoplankton, preventing the emergence of universally dominant phenotypes despite varying trait correlations across different evolutionary scales.
