This paper demonstrates that environmental heterogeneity in graph-structured populations can significantly amplify natural selection and accelerate the fixation of beneficial mutants, particularly when migration is frequent and mutants possess a stronger fitness advantage in demes with high outflow, or when migration is rare and heterogeneity creates refugia.
By analyzing the distribution of derived alleles, this study provides evidence that human ancestors interbred with two distinct superarchaic populations: an earlier-diverging group that contributed to Neanderthals and Denisovans, and a later-diverging group that contributed to early modern humans in Africa.
This study validates the use of seascape genomics to predict kelp declines in the Northeast Pacific by demonstrating a strong correlation between genomic offsets and observed population losses, thereby supporting assisted migration as an effective strategy to mitigate future climate-driven extirpation risks.
This study demonstrates that within a single natural population of *Drosophila serrata*, the mutational variance and bias affecting wing size are highly heterogeneous and dependent on the ancestor's breeding value, with intermediate genotypes showing suppressed mutational decay and larger ancestors experiencing a stronger bias toward size reduction.
This study develops a mathematical model incorporating stem cell dynamics to infer somatic mutation rates and genetic drift patterns in long-lived tropical Dipterocarpaceae trees, revealing how shoot elongation and branching drive genetic mosaicism and providing more accurate mutation rate estimates than previous static approaches.
This study utilizes comparative genomic analyses of eight aquatic and four terrestrial plants to reveal that aquatic re-adaptation involves relaxed selection on nutrient assimilation and enhanced oxidative stress responses, whereas terrestrial evolution is driven by environmental perception and distinct chloroplast protein adaptations to gas availability.
This study establishes a natural predator-prey model using *Pristionchus pacificus* and *Oscheius myriophilus* on beetle carcasses, revealing evidence of a co-evolutionary arms race where the prey's partial resistance and unique mixed reproductive strategy (including internal hatching) likely evolved as countermeasures against predation.
This study demonstrates that Quaternary climatic changes and the Central Valley barrier drove the codiversification of the California carpenter ant *Camponotus laevigatus* and its endosymbiont *Blochmaniella*, resulting in congruent phylogeographic patterns and Pleistocene divergence across three distinct genetic clusters.
This paper introduces the k-Nearest Common Leaves (k-NCL) algorithm, a Python-based method that completes rooted phylogenetic trees with overlapping taxa by utilizing branch lengths and topology to preserve evolutionary relationships, thereby improving clustering performance compared to existing approaches.
This study on Eastern oysters reveals that no single management framework—whether prioritizing local genotypes, maximizing intraspecific diversity, or minimizing environmental distance—reliably predicts transplantation success, indicating that effective restoration strategies require integrating genomic and environmental evidence.
This study reveals that while hybridization outcomes vary across populations of *Mimulus guttatus* and *Mimulus nasutus*, correlated genomic ancestry patterns driven by migration, parallel positive selection, and polygenic interactions—not simple linked selection—shape the evolutionary trajectories of these species across their overlapping ranges.
This study presents the first paleoproteomics evidence of broomcorn millet (*Panicum miliaceum*) consumption in human dental calculus by reanalyzing open-access datasets from the Pontic-Caspian region and Levantine coast, thereby revising the crop's dispersal chronology and demonstrating the potential of dental calculus proteomics to trace underrepresented plant foods in ancient diets.
By analyzing 45,000 UK Biobank genomes, this study provides high-resolution insights into Neanderthal population history and introgression patterns, revealing ongoing selection on Neanderthal segments and identifying Human Accelerated Regions within Neanderthal deserts as potential targets of modern human adaptation.
This study utilizes ancient DNA from 1,862 East Eurasians to demonstrate that, despite distinct timelines for skin depigmentation, East and West Eurasia experienced convergent natural selection on immune and cardiometabolic traits driven by parallel transitions to food-producing economies over the last ten millennia.
This study analyzes 548 global *Nakaseomyces glabratus* genomes to demonstrate that whole-genome sequencing largely confirms multilocus sequence typing clusters, leading to a refined classification system while revealing significant admixture, aneuploidy, and copy number variants that contribute to the pathogen's genomic diversity.
This study reveals that the enhanced olfactory sensitivity of blind Mexican cavefish, which compensates for their loss of vision, is driven by physiological adaptations in the olfactory epithelium—specifically increased cilia motility and reduced water flow—rather than by the expansion of chemosensory receptor genes or neuronal density as predicted by the vision-priority hypothesis.
This study demonstrates that while fitness epistasis in a polygenic trait under stabilizing selection can be neglected when predicting mean phenotypic deviations and genic variance, it is crucial for accurately describing allele frequency distributions, which transition from unimodal to bimodal as effect sizes exceed a specific threshold.
This study reveals that lateral gene transfer, particularly between eukaryotes, is a pervasive and significant driver of genome evolution in Rhizaria, contributing 8–20% of protein-coding genes and shaping functional innovation through distinct patterns of gene retention and duplication.
By integrating comparative morphology, kinematics, and aerodynamics across 133 Dipteran species, this study reveals that insect flight diversity is shaped by the interplay of phylogenetic history, aerodynamic constraints, and scaling laws, where tiny flies prioritize force production through larger wings and higher frequencies while larger species face power limitations that drive increased muscle mass, alongside specific evolutionary trade-offs like the acoustic-muscular adaptation in mosquitoes.
This study demonstrates that in *Ipomoea purpurea*, exposure to an insecticide alters the evolutionary trajectory of glyphosate resistance by increasing resistance levels and weakening the strength of selection, highlighting that herbicide resistance evolution is context-dependent and shaped by interacting environmental stressors.
